Electronic trip unit Ekip M-LRIU connected to the contactor
control unit for starting the motor PR212/CI and with ABB AF
series contactor (the circuit to the motor thermistor is optional)
Description of Figures
Fig. 55 = Auxiliary circuits of the electronic trip unit type Ekip M-LRIU connected to the contactor control unit
for starting the motor type PR212/CI and with ABB AF series contactor (the circuit to the motor
thermistor is optional).
Fig. 62 = Motor thermistor circuit.
Notes
H) Having requested a Uaux insulated from earth, one must use “galvanically separated converters” in
compliance with IEC 60950 (UL 1950) or equivalent standards that ensure a common mode current or
leakage current (see IEC 478/1, CEI 22/3) no greater than 3.5 mA, IEC 60364-41 and CEI 64-8.
