Description
The Ionnic BMS-07 is a compact single-pole battery master switch with a removable L handle key, rated 100A continuous and 500A intermittent across 6 to 36 volt systems. It suits cars, light commercial vehicles, boats, caravans and small equipment where a full heavy-duty isolator is more than the job needs.
Removing the key in the OFF position isolates the battery and prevents the vehicle being started, which also stops slow battery drain during storage. The zinc-plated body has a weather-resistant IP43 rating and the switch connects with M10 studs.
The BMS-07 surface-mounts with Ø 6mm fixing holes. For higher current, lockout brackets or IP66 sealing, step up to the BMS-05 or BMS-12.
