Blue Sea Systems 4100 Toggle Guard for A-Series and B-Series Toggle Circuit Breakers

The Blue Sea Systems 4100 Toggle Guard is a protective cover that fits over a toggle-style circuit breaker to prevent it from being accidentally switched ON or OFF. It is designed for A-Series and B-Series toggle circuit breakers and panel switches, and because it works with any brand of panel using a standard toggle-type circuit breaker, it is a simple add-on for boat owners who want to stop an important circuit, such as a bilge pump or navigation light breaker, from being bumped or knocked off during rough water, gear stowage, or routine panel access.

Installation reuses the existing circuit breaker mounting screw hole, so no new holes or panel modifications are needed, and two mounting screws are included so the guard can be installed as soon as it arrives. The guard sits over the toggle lever, physically blocking casual contact while still allowing deliberate operation of the breaker when needed.
