Schneider Electric J20C30 Contact Block Kit 600VAC

Schneider Electric’s Telemecanique J20C30 Contact Block Kit is a three normally open auxiliary block designed to mount directly on compatible motor starters or contactors, expanding control circuit functionality in industrial motor control and automation systems such as MCCs, conveyors, and packaging lines. It provides 3 NO contacts for dependable auxiliary switching, with a rated operational voltage up to 600 VAC and a rated thermal current of 10 A. The block supports an insulation voltage of 690 VAC (IEC) / 600 VAC (UL) and a rated impulse withstand of 6 kV, with snap-action operation and silver-alloy contacts for reliable performance. Wiring is via screw clamp terminals, and the unit is intended for 50/60 Hz networks, aligning with Telemecanique motor starters and contactors (series dependent). Commonly used for control circuit feedback, interlocking, sequencing, and machine control in industrial equipment, it serves maintenance, retrofit, and replacement needs in process automation and material handling. For compatibility, it is associated with Schneider Electric Telemecanique products and is commonly paired with the LADN30 auxiliary contact block, as well as Siemens 3RH1921 and Eaton XTMCXFA30 as comparable replacements.
