It uses screw-type terminals and is rated for a maximum of 10 A, with specific current ratings that vary by voltage — 6 A at 24 V, 6 A at 125 V, 6 A at 230 V, 6 A at 250 V, 3 A at 400 V, and 0.3 A at 220 V, among others. The block measures 51 mm deep, 44 mm wide, and 38 mm high, and carries an IP20 protection rating on the front.
Snap-on mounting directly onto the 3RT1 contactor or contactor relay — no DIN rail needed, no extra hardware. The screw terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core end processing, or 2x (20 to 16) and 2x (18 to 14) AWG. The block adds 51 mm of depth to the contactor assembly, so check enclosure clearance if retrofitting into a tight panel.
Contact Ratings and Reliability
The 2 NC contacts are rated for AC-15 duty at 690 V at 1 A. Mechanical service life is typical 10 million switching cycles.
