The Mechanical Products Series 53 Branch Disconnect Circuit Breaker, part number 533p006022, combines battery disconnect switching and circuit protection into a single rotary switch device. This integration offers OEM cost savings by eliminating separate components. It is rated for 60A and a maximum voltage of 32VDC, with a higher maximum rating of 42VDC specified in the datasheet.
The breaker features a panel mount design and a push-to-reset actuator. It is tested to UL1077, UL1107, and UL1500 ignition-protected standards, making it suitable for harsh environments. The operating temperature range is -40°C to 85°C. Endurance specifications include overload trip cycles per SAE J553 and switching cycles per UL1107 and UL1077 standards.
Environmental testing includes compliance with MIL-STD-202 for corrosion and humidity, and vibration and shock testing per UL1107 requirements. The device is ignition protected per ISO 8846, USCG, ABYC, UL1107, UL1500, and SAE J1171 standards. Interrupt capacity is rated at 1.5kA @ 28VDC and 3kA @ 14VDC per ABYC standards.
