Current measurement is obtained form the motor line through the magnetic module withour need of external current transformers. From 0.8 up to 25 A with internal current transformers. Over 25 A with external current transformers.     Model Code Range Motor 400V Aux.supply  110/230 Vac-dc Aux.supply  2 4 /48Vdc    (A)   CV   kW   PBM B1 17000 –   0,8 – 6   0,33 – 3   0,25 – 2,2 – 17002   PBM B5 17001 –   4 – 25   3 – 15   2,2 – 11 – 17003 Protections: Overload with termal image Overheating protection Phase imbalance or phase failure Phase sequence JAM detection Locked rotor detection Instantaneous earth leakage overcurrent Earth leakage inverse time overcurrent Instantaneous neutral overcurrent Neutral inverse time overcurrent Undercurrent
