The Mechanical Products Series 53 533p005022 is a branch disconnect circuit breaker rated for 50A and a maximum voltage of 42VDC, with a standard operating voltage of 32VDC. This panel mountable unit incorporates both battery disconnect switching and circuit protection into a single rotary switch, offering OEM cost savings by eliminating separate components.
Designed for harsh environments, this circuit breaker is tested to UL1077, UL1107, and UL1500 standards, ensuring ignition protection. It operates within a temperature range of -40°C to 85°C. The breaker features a push-to-reset actuator and provides superior circuit protection for downstream circuits, preventing unintentional battery drain during storage or maintenance.
Key specifications include a dielectric strength of 2000VAC minimum and interrupt capacities of 1.5kA/U3 @ 28VDC and 3kA/U3 @ 14VDC. Endurance testing per SAE J553 and UL1107 demonstrates its reliability under overload and switching conditions. The unit weighs 90 gm and is compliant with SAE and ABYC standards.
The nominal voltage rating is 32VDC, with a maximum voltage rating of 42VDC.
