Designed for quickly disconnecting the battery from a vehicle's electrical system, Heavy-Duty Single-Pole Series Master Battery Disconnect Switches help prevent potential thermal events and ensure system shutdown during maintenance for the safety of service personnel.
These Cole Hersee brand master battery disconnect switches also prevent parasitic loads from draining the battery during periods of inactivity, such as long-term or seasonal vehicle storage.
With heavy-duty, plated-steel or brass housing options as well as as available models with O-ring and gasket sealing, these master disconnect switches are ideal for heavy-duty truck, construction, emergency vehicle, bus and transit, and agricultural applications.
