Circuit Protection
Protect your electronics with our high-performance circuit protection solutions.
We offer a wide range of fuses, circuit breakers, surge protection devices, and electronic relays designed for industrial, automotive, and other harsh environments.
Our components ensure reliable overcurrent, overvoltage, and short-circuit protection, preventing damage to critical systems.
With robust designs, fast response times, and compliance with industry standards, our solutions enhance safety, extend equipment lifespan, and ensure operational stability.
Circuit Breakers
E-T-A circuit breakers are designed for equipment, component and low voltage wiring protection.
Their precision performance characteristics are ideally suited to applications for which other methods of protections are generally inadequate, such as test equipment, control instrumentation, automotive systems and defence equipments.
Electronic Overcurrent Protection
Electronic overcurrent protection ensures reliable power distribution and safeguards critical components in industrial applications.
Unlike traditional fuses, electronic circuit protectors provide fast, precise protection against overloads and short circuits while allowing remote monitoring and control.
Designed for 24V DC systems, they minimize voltage loss and enhance system reliability in automation, robotics, and machine control.
Fuseholders & Housings
Our fuseholders and housings provide reliable circuit protection for applications like automotive, telecommunications, and industrial equipment.
Available in PCB-mount, panel-mount, and inline configurations, they come in various sizes with features such as snap-in or screw mounting, IP-rated protection, and shock-proof designs.
Designed for durability and efficiency, they ensure safe and stable operation in demanding environments.
We also offer customized solutions tailored to specific requirements, with expert support to help you find the best option for your application.
Fuses
Fuses are electrical protective devices. They are made of a thermoplastic shell and a fusible link in Zinc (Zn) or Copper (Cu) alloy.
MTA’s fuses are developed according to ISO standards, and their range covers blade and bolt down types.
MTA Automotive offers fuses suitable for traditional 12 V systems, as well for the now trending 48 electrical systems.
Power Entry Modules
Power entry modules offer a compact and efficient solution for managing power connections in industrial, medical, and electronic equipment.
Designed for reliability and safety, these modules integrate essential power functions such as input filtering, circuit protection, and switching into a single unit.
With built-in IEC connectors, fuses, and voltage selectors, they ensure secure and convenient power management while minimizing space requirements and simplifying installation.
Available in various configurations, including filtered and unfiltered versions, they enhance EMI suppression and comply with international safety standards.
Ideal for power distribution in control panels, medical devices, and industrial machinery, these power entry modules ensure stable and protected power connections for critical applications.
Types of Circuit Protection
Circuit protection is critical for ensuring safe and reliable operation of electrical systems. The right solution protects equipment from overloads, short circuits, and electrical faults while improving system availability and reducing maintenance. Different technologies are designed for different applications, making it important to select the protection method that best matches your system requirements.
Circuit Breakers
Circuit breakers provide resettable protection against overloads and short circuits. Once a fault has been cleared, they can simply be reset, reducing downtime and maintenance costs compared to replacing a fuse. Thermal, magnetic and hydraulic-magnetic circuit, thermal magneticand high performance circuit breakers are available for different operating conditions and are widely used in industrial automation, commercial vehicles, railway systems, medical equipment and power distribution.
Electronic Overcurrent Protection
Electronic overcurrent protection offers intelligent load protection for modern DC systems. Instead of disconnecting the entire power supply, only the affected circuit is isolated, improving system availability and simplifying fault diagnosis. These solutions are commonly used in industrial automation, machine building, telecommunications, and other applications where uninterrupted operation is important.
Fuse Holders and Fuses
Fuses provide fast and reliable protection by disconnecting a circuit when the current exceeds a safe level. Combined with fuse holders or fuse housings, they create a simple and cost-effective protection solution that is easy to service. This type of protection is widely used in power supplies, control panels, battery systems, industrial equipment, and electronic devices.
Power Entry Modules
Power entry modules combine a power inlet, switch, fuse holder, and often an EMI filter into a single compact unit. By integrating multiple functions, they simplify equipment design, reduce wiring, and save valuable panel space. They are commonly used in industrial equipment, medical devices, laboratory instruments, and commercial electronics where compact and reliable power connections are required.
Finding the Right Circuit Protection
The best circuit protection solution depends on your application, operating environment, and electrical requirements. At EG Electronics, we help customers select the right combination of circuit breakers, electronic overcurrent protection, fuses, fuse holders, and power entry modules to improve safety, reliability, and long-term system performance.
How you can recude Co2 emission by choosing a right type of circuit protection device

Learn how the right solution can improve system reliability, reduce downtime, simplify maintenance and even contribute to lower energy consumption and CO₂ emissions.
About Circuit Protection
Circuit protection is the overall category of components and methods that protect equipment from electrical faults like overcurrent and short circuits. A fuse is one specific circuit protection device that opens the circuit by melting when the current exceeds its rated limit.
A common protection device type is CBE (Circuit Breaker for Equipment), which is designed to carry current in normal operation and automatically disconnect under abnormal conditions. Unlike many fuses, a CBE can often be reset after a trip.
Quick summary
Circuit protection = the full category (fuses, CBEs, electronic protection, surge protection)
Fuse = a protection component that typically needs replacement after it operates
CBE (Circuit Breaker for Equipment) = a resettable protection device used to protect equipment
Choose a fuse when you want simple, cost-effective, and often fast fault protection, and replacement after operation is acceptable.
Choose a circuit breaker or electronic overcurrent protection when you want resettable protection, controlled trip behavior, easier service, or integration into power distribution.
Selecting the right circuit protection solution requires evaluating the operating voltage, current rating, fault current, load characteristics, environmental conditions and applicable industry standards.
Proper coordination between power supplies, wiring and protection devices helps maximize system availability and equipment protection.
Circuit protection products include circuit breakers, electronic circuit protectors, thermal circuit breakers, thermal-magnetic circuit breakers, hydraulic-magnetic circuit breakers, fuses, fuse holders, power distribution modules and intelligent power management systems.
The best solution depends on your application’s electrical requirements and operating environment.
Industrial circuit protection products are used in automation systems, machinery, commercial vehicles, rail applications, marine systems, medical equipment, telecommunications, renewable energy installations and industrial power distribution. They help ensure reliable operation by protecting both equipment and personnel from electrical faults.
