Description
Magnetic Overcurrent Circuit Breaker 808-...
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.
Printed circuit boards and components, safety and control systems.
