Frequently Asked Questions

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

The SCHNEIDER C60H-DC supplementary protector is used for DC circuit protection in industrial control panels, solar arrays, and battery systems. It is a 2-pole UL1077 device rated for 500V DC with a 4 A amp rating and C curve, providing overcurrent protection for DC-only circuits.

What are the specifications of the SCHNEIDER M9U21204 supplementary protector?

The SCHNEIDER M9U21204 is a 4 A, 500V DC supplementary protector with a C curve type and 5kA interrupting rating at 250V DC. It features screw clamp terminals, is not rated for AC, and mounts on a DIN rail. It is part of the C60H-DC series and complies with UL1077.

Where to buy SCHNEIDER C60H-DC supplementary protectors worldwide?

You can source SCHNEIDER C60H-DC supplementary protectors from 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 the M9U21204 model.

How to install a SCHNEIDER C60H-DC supplementary protector on a DIN rail?

To install the SCHNEIDER C60H-DC supplementary protector, snap it onto a standard 35 mm DIN rail. Ensure the DC supply is off, connect wires to the screw clamp terminals per the wiring diagram, and torque to the specified value. The C curve provides magnetic trip for moderate inrush currents.
