Blue Sea C-Series ELCI 50A 120/240v AC Double Pole Main Circuit Breaker

The Blue Sea C-Series ELCI Main Circuit Breaker, model 3104 - BSS, offers reliable over - current and leakage protection for your whole boat's shore power. It meets ABYC E - 11 standards and UL 1500 external ignition protection requirements. This breaker trips on short - circuits, overloads, or ground leakage. It's designed for front - panel mounting in a power distribution panel. With a 50A amperage, flat rocker actuator style, and 3 poles, it's a great choice for boat electrical systems. It can operate in temperatures from - 35°C to 66°C and has a leakage trip of 30mA. It comes with #6 - 32 stainless - steel mounting screws and can handle 10000 switching cycles. Weighing just 0.85lb (0.39 kg), it's a compact and efficient solution for your power protection needs.

Using the Blue Sea C - Series ELCI Main Circuit Breaker is easy. First, make sure to install it in a power distribution panel using the #6 - 32 stainless - steel mounting screws and tighten them to a torque of 6 in - lb (0.68 Nm). Connect your boat's shore power to the breaker according to the correct wiring instructions. When everything is set up, turn on the breaker using the flat rocker actuator. The breaker will automatically protect your boat from over - current, short - circuits, and leakage to the ground. Be aware that the breaker should only be used within its specified temperature range of - 35°C to 66°C. Avoid overloading the breaker by keeping the amperage below 50A. For maintenance, check the breaker periodically for any signs of damage or wear. You can also test it by simulating a short - circuit or leakage situation to ensure it trips properly. After 10000 switching cycles, it might be a good idea to consider replacing the breaker to maintain optimal performance.
