Product details
The REDARC BMIS4PPV2KIT is a Battery Master Isolation Switch with positive isolation designed for heavy vehicles with dual start cables to isolate both battery circuits.

Typically used on high current 12V heavy vehicles, the REDARC Battery Master Isolator Switch is used in heavy vehicles with dual start cables.

The Battery Master Isolator Switch is designed to safely isolate vehicle batteries and ensure reliable performance when the vehicle is operating.

The REDARC Battery Master Isolator Switch will also ensure that no loads are drawn from the vehicle whilst not in use, thereby reducing flat battery faults.

Released in September 2020, the V2 variant of this product supersedes the previous model providing installation compliance with the Dangerous Goods Standard AS2809:2020. 

The Battery Master Isolator Switch meets and exceeds the requirements of large diesel engines in 12 and 24 volt systems and features an ISO 26262 rated dual redundancy system to avoid false triggering.

The Battery Master Isolator Switch by REDARC, fitted as OE at Kenworth is now available for heavy vehicle applications. The REDARC BMIS4PPV2KIT also includes a BMIS-CK connector kit as standard if the BMIS is not installed on a Kenworth. 

For retrofitting installations, REDARC recommends the purchase of the BMIS-AP adaptor plate.

Both the BM1S-CK connector kit and the BM1S-AP can be purchased as separate stand-alone accessories through your local distributor.
