Heavy Duty Battery Disconnect Switch – 12V/24V, 125A, 4 Terminals
 
The C001-079-0128 Heavy Duty Battery Disconnect Switch is designed for manually isolating battery power in 12V and 24V battery-powered electrical systems.
Also known as a battery cut off switch, battery isolator switch, or battery master switch, it features four terminals arranged as two switched contact pairs. Both circuits are connected or disconnected simultaneously through one manual ON/OFF handle.
The switch is rated to carry 125A at 24V for up to four hours and supports an intermittent load of 750A at 12V or 24V for 15 seconds, for three operating cycles.
It is suitable for automotive, truck, RV, marine, agricultural machinery, construction equipment, and industrial battery power applications.

Dual-Circuit Switching Design
The four rear terminals form two switched contact pairs:
A–A
B–B
When the switch is turned ON, both terminal pairs are connected.
When the switch is turned OFF, both terminal pairs are opened simultaneously.
This configuration is suitable for electrical systems that require two circuits to be isolated at the same time. The final wiring arrangement should be confirmed according to the vehicle or equipment electrical design.
