The E-T-A 808-H-1A is a single-pole, polarized circuit breaker featuring a magnetic fast trip mechanism. Its plain switching system ensures disconnection even with the smallest overcurrents, making it suitable for impulse tripping. Designed specifically for PCB mounting, this circuit breaker boasts a space-saving design and low temperature sensitivity due to its magnetic tripping principle.
Key electrical specifications include a rated voltage of 24V DC and a rated current range from 0.01A to 5A. The breaker is approved by CSA C22.2 No 235 and UL1077. It offers a dielectric strength of 1,240V AC and an insulation resistance greater than 100 MΩ at 500V DC.
This circuit breaker is ideal for protecting semiconductors in control and regulation circuits against harmful overcurrents. Its fast tripping provides reliable protection for sensitive PCB components. The resettable nature increases device availability, allowing for quick switching on after an overcurrent event, and prevents nuisance tripping by being perfectly adjusted to the load.
The compact design and PCB mounting capability reduce component count, mounting, wiring, material planning, and storage costs, leading to reduced operating costs compared to fuses.
