Sierra CB50610 Resettable Circuit Breaker 40 Amp Panel Mount Marine

The Sierra CB50610 is a 40-amp resettable circuit breaker designed for marine electrical systems. This panel-mounted breaker provides dual functionality as both a manual switch and automatic circuit protection device, making it ideal for controlling and protecting high-current marine accessories and equipment.

Key Features:

• 40-amp current rating for high-power applications
• Resettable design eliminates the need for fuse replacement
• 1/4" stainless steel studs on rear for secure, corrosion-resistant connections
• Ignition protected design meets USCG/ABYC standards for safe below-deck marine installation
• Trip-free safety feature prevents switch from being held in ON position during fault conditions
• Dual-function operation as both circuit breaker and manual on/off switch
• Panel-mount configuration for easy installation in electrical distribution panels

This breaker is engineered specifically for the harsh marine environment, with ignition protection that prevents sparking in areas where fuel vapors may be present. The trip-free mechanism ensures that if a fault occurs, the breaker will trip to protect the circuit even if the switch is manually held in the ON position, providing critical safety protection for your vessel's electrical system.
