Magnetic Overcurrent Circuit Breaker 808-...

Description
Single pole miniaturised magnetic circuit breakers with unique
high
-speed operating mechanism and push/pull on/off manual
actuation. Fitted with electrically separate excitation and switching
circuits, and one pair of auxiliary contacts which close when the
main circuit is open. Also suitable for impulse operation. Designed for
printed circuit board mounting. Low temperature sensitivity.

Typical applications
Printed circuit boards and components, safety and control systems.
