Sierra CB50660 Resettable Circuit Breaker 150 Amp Panel Mount

The Sierra CB50660 is a heavy-duty 150-amp resettable circuit breaker designed for marine electrical systems. This panel-mount breaker provides dual functionality as both a manual switch and automatic overcurrent protection for high-amperage circuits on boats, yachts, and other marine vessels.

Key Features:

• 150-amp rating for high-capacity electrical circuits
• Resettable design eliminates the need for fuse replacement
• 1/4" stainless steel studs on back for secure, corrosion-resistant connections
• Dual-function operation serves as both a circuit breaker and manual switch
• Trip-free safety mechanism prevents switch from being held in ON position during fault conditions
• Ignition protected design meets safety standards for below-deck marine installations
• Panel-mount configuration for easy integration into electrical distribution panels

This circuit breaker is ideal for protecting main power feeds, inverter circuits, windlass systems, bow thrusters, and other high-draw electrical components in marine applications. The ignition protection and stainless steel construction make it suitable for harsh saltwater environments.
