The 110 A making capacity at 10 MOhm covers momentary inrush from contactor coils or indicator lamps.
Front-mounts directly onto TeSys K contactors and reversing starters — snaps into the front face without tools, adding auxiliary contacts for status feedback, interlocking, or PLC input. The spring terminals accept 0.75 to 1.5 mm² flexible or rigid wire; no screw torque to check, which speeds panel wiring. IP20 finger-safe protection suits enclosed control panels; no washdown rating here.
No official replacement order code is listed in the lifecycle record. A functionally similar TeSys K auxiliary block with the same contact configuration and spring terminals would need to be verified against the specific mounting and wiring requirements of the existing panel.
3NO+1NC contacts, 10 A thermal current (Ith) at 50 °C, 690 V rated insulation voltage (Ui), spring terminals accepting 0.75–1.5 mm² wire, front mounting on TeSys K contactors.
