Ambient air temperature: ambient air temperature -5 degrees -40 degrees, average no more than 35 degrees within 24 hours. Altitude: the altitue of the installation site does not exceed 2000m. Atmospheric conditions: The relative humidity of the air at the installation site does not exceed 50% at a maximum temperature of not more than 20%. Installation method: Using standard Din-rail isntallation. Pullution level: Level II. Istallation conditions: The external magnetic field of the installation site should not exceed 5 times of the geomagnetic field in any direction. The leakage circuit breaker is generally installed vertically, the handle is upwardly connected to the power supply position, and the istallation site should have no significant impact and vibration. Wiring method: Tighten the wiring with screws.

A miniature circuit breaker (MCB) automatically switches off electrical circuit during an abnormal condition of the network means in overload condition as well as faulty condition.

UNION provides reliable and tested miniature circuit breaker built with the first quality material. Union MCB design brings innovative approach to protection of arc chamber by leading the heat flow internally.

PA66 Nonflammable shell, trip units and handle, Q195 steel coated with Zn for the arc chamber and terminal PH joinery form with 24 HRC hardness, 6 aluminum rivet for stronger joints, 2 times ticker shell and heavier material for overcurrent faults and fire prevention
