Description
This Domae product is a low voltage miniature circuit breaker (MCB). It is a 3P circuit breaker with 3 protected poles and 32A In rated current and C tripping curve. The Icn rated short circuit breaking capacity is up to 6000A at 400VAC conforming to EN/IEC 60898-1 standard. This product complies with IEC 60898-1 standard. This miniature circuit breaker protects circuit against short circuit and overload current. The fault tripping is indicated on the front panel by the position of the handle (O-I engraved). It has an electrical endurance going up to 10000 cycles and a mechanical endurance going up to 20000 cycles. The Ue operational voltage is 400VAC. The operating frequency is 50Hz or 60Hz. The product can be clipped on a DIN rail. Its width is 6 pitches of 9mm. The product colour is white (RAL9003). The dimensions are (W) 54mm x (H) 81mm x (D) 78.5mm. The weight is 0.285kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -25°C to 60°C. The storage temperature is -40°C to 70°C.
