Side Post Battery Disconnect Switch, CNAODUN Battery Cut Off Switch with Top Post Negative12-48V Heavy Duty Shut Off for Car RV Boat and Vehicle(On/Off)

Product description

Product Feature:

Designed for DC systems from 12V to 48V, with a simple ON/OFF function. It can sustain a continuous load of 275A at 12V, handle intermittent surges up to 455A, and withstand a peak surge current of 1250A.The no-modification design allows direct attachment to the battery’s negative terminal without the need for additional cables or connectors. Enables quick and reliable disconnection of the electrical system.One side is a top post negative terminal and the other side is a 3/8 screw,compatible with most batteries. Please ensure the screw size matches the battery terminals before making your selection.The housing is made from high-quality flame-retardant ABS material, resistant to sparks. The metal connection components are constructed from premium brass, offering excellent durability, conductivity, and extended lifespan.Provides a safe method to disconnect the battery from the electrical system, preventing power drain during vehicle or boat inactivity. Ideal for use in cars, RVs, and marine applications to protect against battery discharge and leakage.
