The 4 NO pole configuration means all four poles switch together; there are no auxiliary contacts built in, so plan for a separate auxiliary block if your circuit needs feedback or interlocking. Control circuit is 220 V AC 50 Hz, wide-range coil, with a drop-out threshold of 0.3 to 0.6 Uc and pick-up at 0.7 to 1.25 Uc. Inrush power is 95 VA at 50 Hz, cos phi 0.75, which matters for transformer sizing in the control transformer feeding the panel.
Screw-clamp terminals on both power and control circuits accept up to 6 mm² solid or 4 mm² flexible with ferrule. Torque to 1.2 N.m on all terminals. IP20 finger-safe protection means it is suitable for enclosed panels only.
Protective treatment TH per IEC 60068 for tropical climates.
