Product Details

The Blue Sea Systems 7399 is a single-pole A-Series circuit breaker with a flat rocker actuator design, rated for 2.5 amps in both AC and DC applications. This magnetic hydraulic circuit breaker features a trip-free design that cannot be held in the "ON" position during a fault current condition, providing reliable overcurrent protection for marine electrical systems.

Key Features:

  • Flush rocker actuator in the "ON" position eliminates risk of accidental switching
  • Color actuator provides clear visual indication of "OFF" position
  • Trip-free design prevents override during fault conditions
  • International ON/OFF symbols support vertical or horizontal mounting
  • Ideal for protecting 24-hour circuits from accidental interruption
  • Stainless steel terminals and mounting hardware for marine environments

Technical Specifications:

  • Current Rating: 2.5A DC / 2.5A AC
  • Maximum Voltage: 32V DC / 250V AC
  • Poles: Single pole
  • Circuit Breaker Type: Magnetic hydraulic, trip-free
  • Interrupt Capacity: 5000A @ 32V DC / 3000A @ 125V AC / 1500A @ 250V AC
  • Operating Temperature Range: -40°C to 85°C
  • Switching Cycles: 10,000
  • Terminal Screw: #10-32 stainless steel (torque: 14 in-lb / 1.58 Nm)
  • Mounting Screw: #6-32 stainless steel (torque: 6 in-lb / 0.68 Nm)
  • Weight: 0.21 lbs (0.1 kg)

This circuit breaker is designed for marine and other harsh environment applications where reliable overcurrent protection is essential. The flat rocker design is particularly well-suited for installations where preventing accidental circuit interruption is critical.
