Frequently Asked Questions

What is the SCHNEIDER C60H-DC supplementary protector used for?

The SCHNEIDER C60H-DC (MPN M9U31225) is a 25 A, 2-pole, DC-only rated UL1077 supplementary protector for overcurrent protection in DC circuits. It is commonly used in industrial control panels, solar combiner boxes, and battery systems where reliable DC branch protection is required.

What are the specifications of the SCHNEIDER C60H-DC M9U31225?

The SCHNEIDER C60H-DC M9U31225 is a 25 A, 2-pole supplementary protector with a D curve type. It is rated for 500V DC, has a maximum AIR rating of 5kA at 250V DC, and uses screw clamp terminals. It has no AC voltage rating and is DIN rail-mountable per UL1077.

Where to buy the SCHNEIDER C60H-DC M9U31225 worldwide?

You can source the SCHNEIDER C60H-DC M9U31225 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time on this DC supplementary protector.

How to select the right curve type for a SCHNEIDER C60H-DC protector?

For the SCHNEIDER C60H-DC, the D curve type (as in M9U31225) is designed for high inrush loads such as motors, transformers, and DC drives. It tolerates brief current surges up to 10–20 times the rated current, preventing nuisance tripping while still providing overcurrent protection.
