QF17A 5-63A RCBO with 30-300mA sensitivity

QF17A is a very compact RCBO for rated current between 5 and 63A. Standard sensitivity is 30mA but more options are available. The circuit breaker part in QF17A is designed with the same Hydraulic-Magnetic principle as the other CBI MCBs. This means that high or low ambient temperatures is no problem for reliable function. This is then combined with a very exact electronic sensing of earth leakage currents. All together making an excellent product for demanding applications.
