Description
This Domae product is a low voltage miniature circuit breaker (MCB). It is a 3P circuit breaker with 3 protected poles and 16A 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 combines functions of circuit protection against short circuit and overload current, control and isolation. 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.
