Application · TT, TN-S ground system. · Short circuit, overload and earth leakage protection. Working environment · Ambient temperature: -35℃~+70℃ · Altitude: ≤2000m · Relative air humidity: ≤95% · Pollution degree: 2 · Without obvious shock and vibration Features · Short circuit current limiting function. · High breaking capability of rated short circuit. · Easy and reliable "frame" connection. · Standard TH35mm-track installation. · When the breaker normally opens or trips because of failure protection, phase and neutral wire are both in the state of break to keep the neutral wire from charging. · During the operation of make or break, neutral wire connects firstly and breaks later.
