Blue Sea Systems 7258 C-Series Double Pole Circuit Breaker 100A

The Blue Sea Systems 7258 C-Series circuit breaker provides industry-standard AC and DC circuit protection in a compact toggle-switch format with stud terminals. Rated for 100 amperes, this double-pole breaker combines circuit protection and switching into a single device, making it ideal for high-amperage marine applications including windlasses, inverters, bow thrusters, stern thrusters, and other demanding electrical loads.

Key Features:

• Double-pole configuration for simultaneous protection of two circuits
• Magnetic-hydraulic delay trip mechanism handles motor start-up surges without nuisance tripping
• Trip-Free safety feature prevents toggle from being held in ON position during fault conditions
• Compatible with Blue Sea Systems electrical panels for easy installation and retrofitting
• High interrupt capacity of 5000A for robust fault protection
• Suitable for both AC and DC applications
• Backed by manufacturer's lifetime warranty

This circuit breaker's trip-free design ensures that if a fault is detected on either pole, the breaker will trip regardless of toggle position, providing critical safety protection for your electrical system. The magnetic-hydraulic mechanism distinguishes between normal start-up surges and actual overcurrent conditions, reducing false trips while maintaining reliable protection.
