The E-T-A 808-H-0.4A is a single-pole, resettable circuit breaker featuring a magnetic fast trip mechanism. It is specifically designed for PCB mounting, making it suitable for space-saving applications. This breaker operates with a rated voltage of DC 24V and a rated current range of 0.01 to 5A, with this specific model rated at 400mA.
Its magnetic tripping principle ensures reliable protection, largely independent of ambient temperature, making it suitable for various application areas. The fast tripping provides reliable protection for sensitive PCB components against harmful overcurrents. It can be quickly switched on after an overcurrent tripping, preventing nuisance tripping and increasing device availability.
Typical applications include the protection of semiconductors in control and regulation circuits, and use as a safety and control switch. The design reduces operating costs by eliminating the need for fuses and simplifies assembly by reducing mounting and wiring efforts.
