Frequently Asked Questions

What is the rated working voltage for the HD series knife switch?

The HD series knife switches support a rated working voltage of AC 380V and DC 220V, with a rated insulation voltage of up to 660V at 50Hz frequency.

What operating current ratings are available?

Standard models range from 200A to 1600A, while high-capacity configurations can handle current ratings up to 3000A (2500A).

What is the difference between Front and Rear wiring designations?

Based on the type designation code, digit "8" signifies front-mounted wiring (front wiring), whereas digit "9" denotes rear-mounted wiring (rear wiring).

What safety mechanisms are built into the HD11F series?

The HD11F and HD11F2 models include an Anti-Error (Anti-Misoperation) structure and protective covers to prevent accidental contact and switching errors during operation.

Can auxiliary contacts be added to this knife switch?

Yes, the switch designation supports configurations with auxiliary contacts (designated by "1") or without auxiliary contacts (designated by "0").

What is the expected mechanical lifespan of these knife switches?

The mechanical service life depends on the current capacity: units between 200A-400A achieve up to 10,000 operation cycles, 600A-1000A achieve 5,000 cycles, and higher ratings achieve 3,000 cycles.
