Master Switch Disconnects Vehicle Battery

The 75920 Master Battery Disconnect Switch cuts off all battery power from a vehicle’s electrical system. The switch also provides an effective emergency power cutoff, protecting vehicles from tampering, theft, and battery drain. In addition, the switch affords service personnel an extra level of safety, protecting them from hazards, and can be locked-out or tagged-out to satisfy OSHA requirements for energy isolation. The 75920’s composite-engineered polymer housing will not rust or corrode, even when mounted in exposed locations. The switch has been tested in accordance with SAE 1455 for road salt, calcium chloride, and magnesium chloride, and it is waterproof to IP67 standards. The 75920 has a current capacity of 300 A at 12 V dc, can be used in high-side or low-side applications, and fits the standard master disconnect switch mounting pattern. A large red knob allows for easy operation with gloved hands, and 90º switch travel makes it easy to identify the switch position. COLE HERSEE CO., Boston, MA. (617) 268-2100.
