Description

Applications

• Heavy-DutyTruck

• Construction

• Mining

Keep service personnel safe and protect the battery and

electrical systems in your emergency vehicle, tractor,

heavy-duty truck, or boat with the 75920 Series 36V

Master Battery Disconnect Switch.

• Off-Road Vehicles

• Emergency Vehicles

• Marine

• Agricultural Equipment

• Material Handling

The heavy-duty battery disconnect switch ensures the

safety of service professionals by disconnecting the

battery from the vehicle electrical system, safeguards

against battery drain from parasitic loads, and features

built-in lock-out/tag-out for tampering and theft prevention.

Features and Beneﬁts

• High amperage continuous current capacity of 400A with

a single 4/0 cable at 12V DC, 300A at 24V DC, or 200A at

36V DC

• IPX8-rated waterproof battery disconnect switch for

external mounting on vehicles as well as installation on

boats and marine equipment

As an IPX8-rated waterproof battery disconnect switch, it

is ideal for a wide range of vehicles, including construction

equipment, heavy-duty trucks, boats, and vehicles

operating in harsh conditions, such as snowplows and

snow removal equipment. Fitting a standard master

disconnect mounting pattern, the 75920 series can be

used as a drop-in replacement.

• Can be used in high-side or low-side applications

• Black or gray thermoplastic housing with a UL 94 V-0 rating

• Tested per SAE J1455 for salt, calcium chloride, and

magnesium chloride, delivering a rust- and corrosion-free

high-amp battery disconnect

With a large knob that makes manual operation simple,

plus clear switch position markings and 90° switch travel,

the high-amp battery disconnect can effectively be used as

a manual emergency power cutoff switch.

• Large red, yellow, or black knob makes the master battery

disconnect switch easy to operate while wearing gloves,

and the 90° switch travel makes it simple to identify the

switch position

• Built-in lock-out/tag-out (LOTO) satisﬁes OSHA

requirements for an energy isolation device
