Two New Circuit Breaker Designs Provide Protection from Accidental Switching
Toggle actuated circuit breakers and raised rocker circuit breakers can be accidentally tripped. This may be just a nuisance in some situations, but an accidental trip can have serious consequences in other situations, such as when the circuit breaker is in a 24-hour circuit for a bilge pump.
One approach to this situation is two new modern flat actuator designs, one with a built-in reset slot, that are resistant to accidental switching. These circuit breakers are available in two sizesC-Series 2.5 large case, and A-Series 2 small case. Flat actuators are flush in the ON position, eliminating risk of accidental switching. The color actuator indicates the OFF position. The Slot Reset circuit breaker can only be turned off by inserting a small screw driver into the slot.
Flat Slot Reset
These circuit breakers are magnetic-hydraulic. Their trip free design cannot be held ON during a fault condition. They are marked with International ON/OFF symbols which makes them easy to mount vertically or horizontally. Both the C-Series and A-Series breakers from 5A to 250A fit the same panel aperture, the same aperture as the common Raised Rocker. They are CE marked.
