IR2000 SV
High Speed Circuit Breaker type IR2000
The IR2000SV Series is a single pole, magnetic blow out, trip free, High Speed Circuit Breaker.
The closing mechanism is an independent motor operated type. The Circuit Breaker is held closed by holding coil and it is equipped with a direct acting overcurrent trip device which may be either unidirectional and bidirectional. The breaker may be operated as single voltage (750, 1500V) or dual voltage (750/1500V).
The HSCB conforms to EN 60077 Standard.
