FAQ
What is a 4 pole isolator switch?
A 4 pole isolator switch is an electrical device with four separate poles, designed to disconnect all phases (L1, L2, L3) and the neutral line (N) in a 3-phase system. It provides complete electrical isolation for safe maintenance.
Why use an isolator instead of a switch?
Isolators prioritize safety: they disconnect power with visible break points, ensuring no residual current during maintenance. Unlike regular switches, they lack load-breaking capacity and are not for controlling live circuits.
How does a 4 pole toggle switch work?
A 4 pole toggle switch uses a mechanical lever to simultaneously open/close all four poles (3 phases + neutral). Flipping the toggle breaks the circuit, isolating the load from the power source.
Can you use a 4-pole rotary isolator for single phase?
Yes, but only use 2 poles (phase + neutral). Leave the remaining 2 poles unused, ensuring proper labeling to avoid miswiring. Always follow local electrical codes.
What certifications do your contactors have?
Our contactors comply with international safety standards and mainstream certifications for global markets.
Do you support OEM/ODM services?
Yes, we offer OEM/ODM customization for contactors, including branding, specifications, and design tailored to client needs.
