Product Details

The Blue Sea Systems 3119 Enclosed ELCI Main Circuit Breaker Panel provides critical electrical shock protection for boat passengers and swimmers in surrounding water. This complete panel assembly features a 50-amp Equipment Leakage Circuit Interrupter (ELCI) main breaker plus one blank circuit position for customization or future expansion.

ELCI Protection Technology:

The integrated C-Series ELCI main breaker continuously monitors current balance between hot and neutral conductors. If an imbalance is detected—caused by a ground fault in an appliance or faulty grounding wire—the breaker trips immediately to prevent dangerous current leakage into the water. This protection is especially critical in fresh or brackish water where electric shock can paralyze swimmers and cause drowning.

Key Features:

  • 50-amp ELCI main breaker with magnetic hydraulic, trip-free operation
  • One blank circuit position compatible with A-Series and C-Series flat rocker style breakers
  • Watertight SMS enclosure with clear cover for easy breaker status viewing
  • Green LED indicator shows breaker ON position; red LED alerts to reverse polarity
  • Round knockouts with included glands seal wire entries
  • Stainless steel latch and mounting hardware create watertight seal
  • Trip-free feature prevents breaker from being held ON when fault detected
  • Meets ABYC E-11 requirements when installed per manufacturer guidelines
  • IP66 rated protection with cover closed and latched
  • Lifetime warranty

Technical Specifications:

  • Amperage: 50A main breaker
  • Voltage: 240V AC (120V AC per pole)
  • Circuit Breaker Type: Magnetic hydraulic, trip-free
  • Interrupt Capacity: 5,000A
  • Actuator Style: Toggle
  • Dimensions: 7 5/8"H × 7 3/8"W × 4 11/16"D
  • Certifications: UL 508, IP66, NEMA, RoHS compliant

This ready-to-install panel provides essential safety protection while offering flexibility for electrical system customization through the blank circuit position.
