This Acti9 K60H product is a low voltage miniature circuit breaker (MCB). It is a 3P circuit breaker with 3 protected poles and 40A In rated current and C tripping curve. The rated short circuit breaking capacity goes up to 10kA at 415VAC conforming to EN 60898-1 standard and at conforming to standard. This product is compliant with EN/IEC 60898-1 standard. This miniature circuit breaker protects circuit against short circuit and overload current. The connection can be made downstream by biconnect comb busbar. It can be also made upstream/downstream by tunnel terminals. A padlock device is available for work to be carried out on live parts. It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ui rated insulation voltage is 500VAC. The Uimp rated impulse withstand voltage is 4kV. The operating frequency is 50Hz or 60Hz. It can be mounted on DIN rail for modular installation. Its width is 6 pitches of 9mm. The product colour is white (RAL9003). The dimensions are (W) 54mm x (H) 81mm x (D) 70mm. The weight is 0.36kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -5°C to 55°C. The storage temperature is -25°C to 85°C.
