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 provides overcurrent protection for sensitive equipment where a full branch-circuit breaker is not required, with a 20 A rating and C curve for moderate inrush currents.

What are the specifications of the SCHNEIDER M9U21220 supplementary protector?

The SCHNEIDER M9U21220 is a 2-pole DC-only supplementary protector rated 20 A at 500V DC, with a C curve and 5kA interrupting rating at 250V DC. It uses screw clamp terminals, mounts on DIN rail, and complies with UL1077. AC voltage is not rated.

Where to buy SCHNEIDER C60H-DC supplementary protectors worldwide?
