Cole Hersee Company, a leading manufacturer of heavy-duty electrical, electronic, and digital products for the vehicle industry, introduces its new Master Battery Disconnect Switch. Ideal for all vehicle electrical systems, including heavy truck, off-road, construction, emergency vehicles, material handling, refuse collection, mining, agricultural and marine, the 75920 Master Battery Disconnect Switch cuts off all battery power from the vehicle electrical system. Cole Hersee's Master Battery Disconnect Switch also provides an effective emergency power cutoff, protecting vehicles from tampering, theft and battery drain. The Switch also provides service personnel with an extra level of safety, protecting them from hazards, and can be locked-out or tagged-out to satisfy OSHA requirements for energy isolation. Even when mounted in exposed locations, the 75920 Master Battery Disconnect Switch’s composite engineered polymer housing will not rust or corrode. The Switch has been tested per SAE 1455 for road salt, calcium chloride and magnesium chloride, and it is waterproof to IP67. The 75920 Master Battery Disconnect Switch has a high amperage capacity of 300A at 12V DC, can be used in high side or low side applications, and fits the standard Master Disconnect Switch mounting pattern. The Switch's large red knob allows for easy operation with gloved hands, and 90º switch travel makes it easy to identify the switch position. • Operating temperature range -40 to +85 °C • Ingress protection rating IP67 • Corrosion test 96 hours • Vibration test 10-500Hz • Battery terminals 5/16” - 24 • Mounting hardware 3/4” – 16 • Operating voltage 6V min, 36V max • Continuous current 12V: 300A max
