Meterk Side Post Battery Disconnect Switch

The Meterk Am-CBS02C is a side post battery disconnect switch rated for DC 12 to 48 volt systems. It provides an on/off isolator for cars, RVs, boats and other electrical equipment. A removable knob acts as the key to cut power quickly. The switch handles 300 amps continuous and 500 amps intermittent at 12 volts.

Check Battery Terminal Type Before Fitting

Verify that your battery uses a standard GM side post with a 3/8 inch 16 thread terminal. The kit includes two SAE bolts for direct mounting without extra cables or lugs. An adapter is supplied to convert the side post to a 17 millimetre negative top post if required. Buyers with top post only batteries cannot use the direct mount feature.

Thermals Noise And Power Draw In Normal Use

The ABS plastic housing insulates the contacts during operation. With no moving fans or active electronics the switch runs silently. Power draw is zero when the knob is in the off position, eliminating parasitic drain. The steel mechanism and 20 horsepower rating support the 1300 amp momentary surge capacity without overheating.

Questions about this item

What comes with the Meterk Am-CBS02C and do I need extra cables or lugs?

The kit includes the switch, a removable knob, two SAE 3/8"-16 bolts and a post adapter that converts the side post to a 17 mm negative top post; no additional battery cables or lugs are required.

Which version of the disconnect switch should I choose for my DC system voltage?

This single model covers DC 12 V to 48 V systems with a 300 A continuous, 500 A intermittent and 1300 A momentary rating at 12 V.

What does the 300 A continuous rating mean when the switch is installed in my vehicle?

It means the switch can carry 300 A continuously at 12 V DC, handle 500 A intermittently and survive a 1300 A momentary surge, so it will support typical starter and accessory loads without overheating.
