Combined switch and breaker runs to 100A
E-T-A has modified of one of its combined switch/circuit breakers for equipment to offer what is believed to be the only high-performance 100A CBE with an auxiliary contact for status information.
E-T-A is offering a modified version of one of its combined switch/circuit breakers for equipment (CBEs) to offer, what is believed to be, the only high-performance 100A CBE with an auxiliary contact providing status information The new E-T-A 452 is a heavy duty, combined push/pull switch and circuit breaker with a thermal-magnetic tripping mechanism for thread-neck, panel mounting in low voltage applications

Combined switch/circuit breaker for simulators
E-T-A has introduced a new combined switch/circuit breaker which has been designed especially for aircraft simulators, and has exactly the same 'feel' as E-T-A's operational flight-deck products
The addition of an auxiliary contact to the standard model offers the user a low current, status indicator signal.
The standard E-T-A 452 is used widely to populate flight decks of aircraft, and for other high- performance applications including telecommunications and process control.
The new CBE is available in a range of current protection values from 50 to 100A.
The E-T-A 452 CBEs feature a tease-free, trip-free, snap-action mechanism ideal for applications requiring reliable, rugged performance particularly when subject to vibrations.
As with all E-T-A thermal-magnetic CBEs, an internal solenoid provides rapid cut off in the event of short-pulse high current overloads, and the bimetal thermal cutout, in series with this solenoid, responds to prolonged low value overloads. Request a free brochure from E-T-A Circuit Breakers ...
