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.
High Performance Circuit Breakers
High performance circuit breakers are ideally suited to protect against overcurrent and short circuit for use in aircraft and vehicles and other specialised equipment where safety is paramount.
High performance circuit breakers feature thermal or thermal-magnetic trip and an extremely high rupture capacity. Battery isolation switches are also based on a thermal-magnetic trip mechanism.
The thermal part of the circuit breaker provides delayed protection in the event of overload, the magnetic part disconnects the faulty circuit in the event of overload or short circuit within milliseconds.
Customized High Performance Circuit Breakers such as SG, AP or CBM types are available on request.
Magnetic & Hydraulic Overcurrent Circuit Breakers
Magnetic and hydraulic circuit breakers are ideally suited to protect against overcurrent and short circuit of printed circuit boards, semi-conductors and telecommunications equipment.
Circuit breakers with magnetic or hydraulic-magnetic trip mechanism respond extremely fast and provide genuine physical contact isolation.
Magnetic trip ensures disconnection of the faulty circuit nearly without delay in the event of short circuit, but also in the event of low overloads. E-T-A models also provide hydraulically delayed switching characteristic required for certain applications.
Thermal Magnetic Overcurrent Circuit Breakers
Thermal-Magnetic overcurrent circuit breakers are ideally suited to protect against overcurrent and short circuit of equipment in telecommunications, process control and other industrial applications where sophisticated equipment requires a high precision performance.
E-T-A has perfected thermal magnetic technology to provide a choice of mounting options, covering an extensive range of current ratings all with high precision performance.
Thermal Overcurrent Circuit Breakers
Thermal circuit breakers offer one of the most reliable and cost effective forms of protection device available, thanks to the simple operations through the heating effect of current.
As a result they are ideally suited to the protection of a broad range of components and systems such as transformer windings, printed circuit boards, low voltage power distribution circuits of road vehicles and battery powered machines.
