Blue Sea 7250I C-Series Ignition Protected Toggle Single Pole - 100A

The Blue Sea 7250I C-Series Ignition Protected Toggle Single Pole 100A switch is a marine-grade circuit breaker designed to provide both switching control and overcurrent protection in a single compact device. Built to withstand the demanding electrical demands of modern marine systems, this 100-ampere toggle switch combines the reliability of a manual disconnect with automatic trip protection, eliminating the need for separate components in tight engine compartments and electrical panels.

The ignition-protected design means the switch cannot be held in the closed position once an overload occurs—a critical safety feature known as "trip free" that prevents dangerous arcing and thermal runaway in high-amperage circuits. The 100A rating makes this switch ideal for protecting inverters, bow thrusters, windlasses, and other substantial auxiliary loads common on cruising sailboats and powerboats. Blue Sea Systems engineered this switch to perform reliably in salt-air environments where corrosion and electrical degradation pose constant threats to system integrity.

This single-pole configuration suits 12V and 24V DC marine electrical systems where a straightforward on/off switch with integral protection is required. Serious cruisers upgrading to higher-capacity auxiliary systems, weekend anglers installing electric windlasses, and boaters retrofitting inverter systems all benefit from having a manual override that automatically disconnects power under fault conditions. The toggle actuator offers positive tactile feedback, making it simple to verify circuit status at a glance in low-light engine compartment conditions.
