Miniature circuit breaker, Easy9, 2P, 63 A, C curve, 3 kA

The residual current circuit breakers have been designed with improving protection levels in mind, providing enhanced leakage current protection to ensure all users avoid any electric shocks. Dependable, secured and designed to be easy to use, they are a must-have protection measure.

This Easy9 product is a low voltage miniature circuit breaker (MCB). It is a 2P circuit breaker with 2 protected poles and 63A In rated current and C tripping curve. The Icu rated short circuit breaking capacity is up to 3kA at 400VAC conforming to EN/IEC 60898-1 standard. It is compliant with IEC 60898-1 standard. This product has a protection against short circuit and a protection of cable against overloads. It has a fault tripping indication on the front panel by the position of the handle (O-I engraved). This product is dedicated for residential and small commercial buildings. It has an electrical endurance going up to 4000 cycles and a mechanical endurance going up to 10000 cycles. The Ue operational voltage is 400VAC. 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 4 pitches of 9mm. The product colour is light grey (RAL7035). The dimensions are (W) 36mm x (H) 81mm x (D) 66.5mm. The weight is 0.2kg. According to IEC 60529 standard, the degree of protection is IP20 and IP40 in enclosure. The operating temperature is -5°C to 60°C. The storage temperature is -40°C to 85°C.
