About this product

The Blue Sea Systems C-Series Toggle Circuit Breaker delivers reliable overcurrent protection for demanding marine DC and AC circuits. With a robust magnetic-hydraulic trip design, high interrupt capacity, and stud-style terminals, it's ideal for main circuit, inverter, and heavy-duty load protection. The trip-free mechanism cannot be held in the ON position during a fault current condition. That matters on board because a breaker should open the circuit when a fault occurs, even if someone is holding the toggle.

This C-Series triple-pole toggle breaker is offered in multiple amperage ratings. The pole count, white toggle format, voltage ratings, trip-free magnetic hydraulic construction, and 5,000A AC interrupt capacity remain consistent across these configurations. This breaker is intended for panel mounting in a protected electrical distribution location. The terminal stud torque is 35 in-lb, and the mounting screw torque is 6 in-lb, so installation should be done with the correct tools and torque values rather than by feel alone.

Key Features

• Triple-pole C-Series breaker for marine AC main protection and switching.
• Available in 50A, 60A, 80A, and 100A AC ratings to match the required circuit and conductor sizing.
• Magnetic hydraulic trip-free breaker type, so the toggle cannot override a fault trip.
• Rated for 120V AC, 240V AC, and 80V DC maximum system voltage.
• 5,000A interrupt capacity at 125V AC and 240V AC for high-fault-current protection in properly specified systems.
• All poles trip together when any one pole trips, helping disconnect the protected circuit in a controlled way.
• White toggle actuator suits many marine AC distribution panels and keeps operation simple at the panel face.
• 1/4-20 tin-plated brass terminal studs and #6-32 stainless steel mounting screws support marine panel installation.
• Operating temperature range from -40 degrees C to 85 degrees C for use across a wide range of onboard conditions.
• UL 1077 regulatory specification for supplementary circuit protection applications.
