Information
This Acti9 NG125H product is a low voltage circuit breaker. It is a 2P circuit breaker with 2 protected poles and 63A In rated current and C tripping curve. The rated short circuit breaking capacity goes up to 36kA at 380VAC to 415VAC conforming to EN/IEC 60947-2 standard and 36kA at 380VAC to 415VAC conforming to EN/IEC 60947-2 standard. It complies with both industrial standard EN/IEC 60898-1 and residential standard EN/IEC 60947-2. This miniature circuit breaker protects circuits against short circuit and overload current. It is suitable for isolation in the industrial sector according to IEC/EN 60947-2 standard. The fault tripping is indicated by a red mechanical state indicator light on the front face of the circuit breaker. It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ue operational voltage is going from 380VAC to 415VAC. The Ui rated insulation voltage is 690VAC. The Uimp rated impulse withstand voltage is 8kV. The operating frequency is 50Hz or 60Hz. It is DIN rail mountable. Its width is 6 pitches of 9mm. Pollution degree is 3. Overvoltage category is IV. The dimensions are (W) 54mm x (H) 103mm x (D) 81mm. The weight is 0.48kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -30°C to 70°C. The storage temperature is -40°C to 70°C.
