This E-T-A 808-H-4.5A is a single-pole, resettable circuit breaker with a magnetic fast trip mechanism. It is designed for PCB mounting and offers a rated voltage of DC 24V and a rated current range of 0.01A to 5A.
The breaker's plain switching system ensures disconnection even with small overcurrents and is also suitable for impulse tripping. Its small design saves space, making it ideal for compact electronic assemblies. The magnetic tripping principle ensures the function is largely independent of ambient temperature, providing reliable protection for sensitive PCB components.
Applications include the protection of semiconductors in control and regulation circuits against harmful overcurrents, and use as a safety and control switch. The device offers reduced operating and component costs compared to fuses, as it prevents nuisance tripping and can be quickly switched back on after an overcurrent event.
The breaker supports 120VAC and 60VDC operation.
It is designed for printed circuit board (PCB) mounting.
It utilizes a magnetic trip mechanism.
The dielectric strength is 1,240 VAC across operating and circuit interfaces.
It features a push-pull plunger actuator.
