Ideal for all vehicle electrical systems, including heavy truck applications, the 75920 Master Battery Disconnect Switch cuts off all battery power from the vehicle electrical system. Cole Hersee Company, the Commercial Vehicle Products division of Littelfuse, Inc. and a leading manufacturer of heavy-duty electrical, electronic, and digital products for the vehicle industry, will showcase its Master Battery Disconnect Switch and its new FlexMod™ LVD at The Work Truck Show, March 6-8, at the Indiana Convention Center in Indianapolis, in booth #733. Ideal for all vehicle electrical systems, including heavy truck applications, the 75920 Master Battery Disconnect Switch cuts off all battery power from the vehicle electrical system. The FlexMod™ LVD is part of a family of configurable electronic modules that protect batteries and battery powered equipment.

Cole Hersee's Master Battery Disconnect Switch 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.

FlexMod LVD ensures that vehicles will start by controlling non-essential loads that can kill a battery. The module is ideal for those with fleets of emergency vehicles, delivery vehicles, boats, buses or utility trucks.
The FlexMod LVD automatically shuts down non-essential loads when the battery runs low, and automatically restores the non-essential loads when the battery power returns to normal levels. Typical applications include idle reduction for work vehicles, NFPA 1901 Load Manager compliance for fire vehicles, combined timer/voltage shutoff for police vehicles, and smart charging system for boats. 

The FlexMod family has two inputs (one analog and one digital) and two solid state outputs (one 10A, one 200mA) that can be programmed to do almost any job.

Several standard units have been created to specific application needs, including the 48610 Electronic Low Voltage Disconnect which preserves battery charge and protects battery banks; the 48636 Electronic Timer for Interior Lighting, which prevents the internal lights inside a vehicle from being left on and draining the battery; the 48540 Smart Battery Isolator Controller, which monitors two battery banks and controls one or more relays or contactors to protect starting power; and the 48541 Electronic Voltage Sensing Relay & Timer, which monitors both battery voltage and ignition status, shutting down non-critical loads when the cutoff voltage is reached. Custom parameters can be programmed into one of the off-shelf modules at the Cole Hersee factory.
