Frequently Asked Questions

Q: Is this battery disconnect switch compatible with 48V systems?

A: Yes! This switch is rated for 12V, 24V, and 48V DC electrical systems, making it suitable for a wide range of vehicles and applications including cars, boats, RVs, and solar setups.

Q: What does the M10 terminal size mean?

A: M10 refers to the terminal post diameter of 3/8 inches (approximately 10mm). This is a standard size that fits most heavy-duty battery cables and ring terminals used in automotive and marine applications.

Q: Can I use this switch on a marine boat in wet conditions?

A: Yes. The switch features tinned copper terminals that resist corrosion and is designed to handle the demanding moisture-rich environment of marine use. However, always ensure proper installation away from direct water submersion.

Q: What is the difference between the continuous and cranking amp ratings?

A: The continuous rating (275A) refers to sustained current the switch can handle for up to 1 hour. The cranking rating (1,250A) is the peak current it can manage for 10 seconds — such as when starting a vehicle engine. The intermittent rating (455A) covers short bursts up to 5 minutes.
