For fleet managers, equipment operators, and anyone who depends on reliable electrical system control, Cole Hersee TR Series Manual Battery Disconnect Switches provide safe, reliable power isolation for fleet, construction, agricultural, and heavy-duty vehicles. With a legacy dating back to 1924, Cole Hersee has established itself as a pioneer in heavy-duty electrical switching solutions, and their manual battery switches represent some of the most trusted components in the industry.
TR Series: Advanced Manual Battery Disconnect Technology
The Cole Hersee TR Series sets the standard for modern manual battery disconnect switches. Ingress protection to IP67 and IP69K means that the switch can be mounted in exposed locations on the vehicle, making these switches ideal for off-road equipment, construction machinery, and agricultural vehicles that face harsh environmental conditions. Drop-in replacement for competitive Master Disconnect Switches, with higher vibration and shock capabilities, the TR Series offers superior durability in demanding applications. These switches also feature direct lockout/tagout capability in On or Off position, with padlock or hasp, providing essential safety functionality for maintenance and compliance requirements.
SPST and DPST Manual Disconnect Options
Manual Battery Disconnect Switches by Cole Hersee comes in both Single Pole Single Throw (SPST) switches and Double Pole Single Throw (DPST) switches. SPST models are ideal for straightforward battery disconnect applications, while Double Pole Master Disconnect Switches will disconnect the battery and the alternator or generator field circuit. This dual-pole design prevents damage to charging systems and is particularly important for modern alternators. Cole Hersee offers these switches in various current ratings, from UL-listed 20-40A models up to heavy-duty 300A continuous-rated units, with brass or plated steel cases to suit different environmental requirements.
Engineered for Heavy-Duty Reliability
Cole Hersee manual battery switches are built to withstand the punishment that commercial and industrial vehicles endure daily. They are designed to help prevent tampering, theft, battery drain and electrical fires. They are available with brass or plated steel cases and are actuated by lever or hencol key. Contact materials include silver-plated or copper options, each chosen for specific current-carrying capabilities and environmental resistance. Many models feature O-ring seals in the operating shaft, along with epoxy and gasket sealing, providing multiple layers of protection against moisture, dust, and contaminants.
Applications Across Industries
Whether you're maintaining a municipal fleet, managing construction equipment, or operating agricultural machinery, Cole Hersee manual battery switches deliver the combination of safety, durability, and ease of use that demanding applications require. The make-before-break design in selector models permits safe operation, while indexing pins prevent rotation and ensure proper switch alignment.
