Product Details

The Blue Sea Systems 4126 AC A-Series Circuit Breaker Lockout Slide is a critical safety device that prevents simultaneous activation of multiple AC power sources on your vessel. This lockout mechanism ensures that shore power, generator power, and inverter power cannot be inadvertently connected at the same time, protecting your electrical system from dangerous backfeeding and potential damage.

Key Features:

  • Allows only one double pole AC circuit breaker to be activated at a time
  • Prevents mixing of AC power from 2 or 3 sources (shore power, genset, and inverter)
  • Compatible with all Blue Sea World Series, A-Series, and Rocker double pole circuit breakers
  • Simple installation using existing circuit breaker mounting screw holes
  • No panel modification required for installation
  • Includes all necessary mounting hardware
  • Three position configuration for managing multiple power sources
  • Two pole design for standard AC applications

This lockout slide is an essential component for boats with multiple AC power sources, providing foolproof source selection and eliminating the risk of connecting incompatible power sources. The mechanical interlock design ensures reliable operation and peace of mind when switching between shore power, generator, and inverter systems.
