Can I use a 1P or 2P WiFi breaker on a 3-phase circuit?

No. For a true 3-phase load you must use a 4P or minimum 3P breaker. Using a single-pole breaker on one phase is dangerous because the other two phases stay live.

Is a 3P breaker enough or do I need 4P?

3P is enough for pure 3-phase loads like isolated motors. For mixed loads, building mains, solar outputs, or TN-C-S earthing, use 4P for full isolation.

What's the maximum amp rating for a 3-phase WiFi breaker in Pakistan?

CNC 4P WiFi breakers go up to 100A. Above that you move to MCCB class with a separate smart controller.

Can I use a 3-phase WiFi breaker with a single-phase pump?

Technically yes but wasteful. Single-phase pumps should use 2P WiFi breakers. Use 4P only when the pump itself is 3-phase.

Does the 4G backup version work in rural Pakistan?

Yes, with any standard 4G data SIM from Jazz, Zong, Ufone, or Telenor. The breaker uses cellular as a fallback when WiFi is down.

Can I monitor individual phases separately?

Yes. CNC 4P WiFi breakers expose per-phase voltage, current, and power draw in the Tuya Smart app.

Ensure your three-phase electrical equipment runs smoothly with CNC Electric Phase Sequence Relays. Designed for industrial, commercial, and heavy-duty applications, these relays continuously monitor phase sequence, phase loss, and voltage levels, preventing damage to motors, pumps, compressors, and other sensitive equipment.

A wrong phase sequence or phase failure can cause motors to run in reverse, overheat, or fail completely. CNC Phase Sequence Relays automatically detect these issues and disconnect the load when necessary, providing reliable and hassle-free protection. Compact, durable, and easy to install, these relays are an essential addition to control panels, distribution boards, and industrial electrical systems.
