Egis Mobile Electric 3221-40 A-Series Single Pole Toggle Panel Mount Circuit Breaker - 40A Red

The Egis Mobile Electric 3221-40 is a magnetic-hydraulic A-Series single pole circuit breaker rated at 40 amps, featuring a red toggle actuator for easy panel-mount installation. Designed to combine manual on/off switching with automatic circuit protection in a single compact device, it is the industry-standard choice for marine electrical panels, RV systems, and other demanding mobile electrical applications.

This breaker protects electrical circuits from short-circuit events and over-current loads, preventing wire insulation overheating and potential damage. Its Trip-Free design ensures the breaker cannot be held in the "on" position during a fault condition, providing reliable protection at all times.
