It mounts directly onto the front of a TeSys Deca contactor or reversing starter, adding status feedback or interlocking without extra panel space. Rated for 10 A conventional free-air thermal current at 60 °C, it handles 6 A at 120 V AC-15 (solenoid loads) and 0.55 A at 125 V DC-13 (DC solenoid/brake loads). Making capacity is 140 A AC and 250 A DC per IEC 60947-5-1, meaning it can close onto a short-circuit without welding for faults within that peak.
The block clips onto the front of the contactor — no tools needed for mounting. Dimensions are 48 mm high, 26 mm wide, 42 mm deep, so it adds minimal depth to the contactor body. Terminals accept lugs-ring terminals with an 8 mm outer diameter; tighten to 1.7 N·m with a flat or Philips No. 2 screwdriver. Altitude limit is 3000 m without derating.
