Technical content
Single-pole, polarised circuit breaker with magnetic fast trip me- chanism. A plain switching system ensures disconnection even in the event of smallest overcurrents. Also suitable for impulse trip- ping. The small design is specifically suitable for PCB-mounting. Only low temperature sensitivity. MAGNETIC CIRCUIT BREAKERS 808 TYPICAL FEATURES YOUR BENEFITS
- Single pole, resettable circuit breaker with magnetic fast trip me- chanism.
- Rated voltage: DC 24 V
- Rated current: 0.01 - 5 A
- PCB mounting
- Increased device availability: the circuit breaker can be quickly and conveniently switched on after an overcurrent tripping. The over- load protection is perfectly adjusted to the load, nuisance tripping is prevented.
- Space-saving design
- Reduced operating costs: no procurement, stocking, disposal and service costs, as incur when using fuses.
- Reduced costs: the circuit breaker saves components and reduces mounting and wiring efforts as well as material planning and stora- ge costs.
- Very fast tripping provides reliable protection specifically of sensiti- ve PCB components.
- Many application areas thanks to temperature insensitivity. Due to the magnetic tripping principle, the function of the circuit breaker is largely independent to the ambient temperature.

Sealing (higher IP protection class) prevents the ingress of hum idity or foreign objects into the circuit breaker. Terminal area: the circuit breaker term inals are located here. Hum idity or foreign objects cannot enter the term inal area through the cover (increased degree of protection) or penetrate the circuit breaker through openings at the back. ORDERING NUMBER CODE H A
