    FAQ

    Q1: What is the difference between 2-pole and 4-pole ATS?

    The core distinction lies in pole quantity, which equals the number of conductive circuits. 2-pole ATS switches two live wires between mains and backup power, fitting single-phase power supply systems. 4-pole ATS supports three live wires plus a neutral wire for simultaneous switching, designed for complex three-phase electrical systems. You can select the matching ATS model according to your single-phase or three-phase circuit layout.

    Q2: What does ATS CB Level mean?

    CB-Class ATS adopts circuit breaker structure with built-in overload and short-circuit protection. It can automatically switch two power sources and reset after power recovery, with a transfer time within 2 seconds, suitable for household, commercial and small industrial standby power distribution.
