The E-T-A 808-H-4A is a single-pole, resettable circuit breaker featuring a magnetic fast trip mechanism. This design ensures disconnection even with small overcurrents and is suitable for impulse tripping. Its compact size is specifically designed for PCB mounting, saving valuable board space.
With a rated voltage of 120V AC and a rated current range of 0.01A to 5A, this breaker is ideal for protecting sensitive components. The magnetic tripping principle ensures that its function is largely independent of ambient temperature, offering reliable performance across various applications. It provides increased device availability as it can be quickly switched back on after an overcurrent event, preventing nuisance tripping.
This circuit breaker is suitable for protecting semiconductors in control and regulation circuits against harmful overcurrents. It also serves as a safety and control switch. The UL 1077 and CSA C22.2 No 235 approvals indicate its suitability for various industrial applications. The PCB mounting type simplifies integration into electronic designs.
The breaker is rated for 120VAC and 60VDC.
