Key Features
【1】High Adaptability & Watertight Design: This product can adapt to 12V-36V DC voltage, with a rated current of 500A and an instantaneous peak current of up to 5000A. It can directly replace model 20247. It is also equipped with a 10mm nut terminal post, designed specifically for the negative pole of the battery. The whole machine is made of metal and has watertight sealing technology, making it stable and not easily damaged for use in the humid environments of vehicles and boats.

【2】Excellent Performance: This product comes with a lock-out plate, and turning the knob can quickly disconnect the power supply. Meanwhile, its thickened heavy-duty rotating handle is fitted with a hanging lock hole, which can firmly lock the switch after locking, avoiding accidental contact with the switch to start or stop the circuit and preventing outsiders from connecting the power supply or tampering with the circuit without authorization.

【3】Reliable Design: This product cuts off the main battery power supply when equipment sits idle for long periods, effectively preventing short-circuit fires and vehicle theft. It can offer construction safety by cutting off power before maintenance and modification, while isolating static power consumption, avoiding battery depletion and aging, and extending the service life of the battery.

【4】Widely Applicable: This product is compatible with various vehicle models and agricultural machinery, and covers the vast majority of 12-36V DC battery equipment, providing a wide range of applicable scenarios.

【5】Easy to Use: Unlike remote power switches, this product does not require programming or pairing coding, and can be assembled simply by wiring, making it easy to use.

Notes
Please allow the slight color difference caused by the shooting light and a 1-3cm error due to manual measurement, and make sure you do not mind before ordering.
