About this product

The Blue Sea A-Series ELCI Main Residual Current Toggle Circuit Breaker provides whole boat AC circuit protection. ELCIs are part of a larger family of devices that measure current flow in the hot and neutral wires and immediately switch the electricity off if an imbalance of current flow is detected. ELCIs that are also Residual Current Circuit Breakers (RCBO) provide overcurrent tripping protection characteristic of a normal circuit breaker. Installed as required, within 10' of the shore power inlet, an ELCI provides 30mA ground fault protection for the entire AC shore power system beyond the ELCI.

Key Features

• Trips on short circuit, overload, or leakage to ground, helping protect the AC system from both overcurrent faults and current leaving the intended circuit path.
• ELCI main configurations provide overcurrent and leakage protection for whole-boat shore power protection under ABYC E-11 applications.
• GFCI branch configuration supports protected receptacle circuits in head, galley, machinery, and weather deck locations.
• Magnetic hydraulic, trip-free breaker action means the breaker cannot be held closed after a trip condition.
• Flat rocker actuator sits flush in the ON position, helping reduce accidental switching in a power distribution panel.
• Front panel mount format fits installation in an AC distribution panel or compatible marine panel enclosure.
• 5,000A interrupt capacity and 10,000 switching cycles support demanding onboard AC service.
• Ignition-protected ELCI configurations are suitable for installations where ignition protection is required.
• Uses #6-32 stainless steel mounting screws with a specified mounting screw torque of 6 in-lb, or 0.68 Nm.
