Switch Power Safely with Power Switches

Our broad power switch portfolio includes battery disconnect switches for the most demanding requirements. Battery disconnectors allow for an immediate power interruption by manual activation for increased safety factors in field installation. A battery disconnect switch cuts off the connection between a battery and accessories that can drain it. It lowers the chances of the battery malfunctioning and protects it against electrical fires and theft. Battery disconnect switches also provide a reliable way to shut down power during maintenance and protect batteries from excessive drain.

We offer single- or dual-pole configurations, various mounting and locking (security) alternatives as well as different shapes and colors for the operating handles.  Battery disconnect switches are used in applications such as commercial motor and off-road vehicles as well as in plant and industrial engineering. Our manually operated battery disconnects range from 200 A to 500 A and meet the most demanding requirements in all vehicle applications. The nominal current ratings refer to continuous DC current at up to 100% duty cycle, and the switches are built to switch under full load and can handle up to 5 times the continuous current level for up to 10 seconds as overload current. All Series 35 battery disconnectors are sealed with a technology that meet the IP 67 and IP6K9K standards, and the switches are designed to operate at temperatures between -40°C and +85°C.
