Product Details

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

Technical Specifications:

  • Amperage Rating: 100A (AC: 50-100A, DC: 50-300A range available)
  • Number of Poles: 2
  • Maximum Voltage: 240V AC, 65V DC
  • Circuit Breaker Type: Magnetic hydraulic, trip-free
  • Interrupt Capacity: 5000A @ 240V AC, 5000A @ 65V DC
  • Terminal Stud: 1/4-20 tin-plated brass
  • Mounting Hardware: #6-32 stainless steel screws

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.
