Schneider Electric GV3A01 Auxiliary Contact Block

GV3A01 is a TeSys GV3 auxiliary contact block that adds a single normally open (NO) and normally closed (NC) contact to a GV3 motor starter or protector, enabling signaling and interlock functionality within the GV3 family. Rated for up to 6 A, it supports a broad control-voltage range—48 to 690 VAC or 24 to 220 VDC—and uses screw-clamp terminals suitable for 0.75–2.5 mm² conductors, with GV3ME compatibility ensuring seamless integration with TeSys GV3 devices. The block provides 1 NO and 1 NC contact, allowing it to relay status signals or provide control feedback to PLCs and automation systems in motor control and industrial automation applications. Designed as a compact accessory for the TeSys GV3 lineup, the GV3A01 does not consume main contacts, freeing space on the contactor while expanding its signaling capabilities. Typical applications include signaling, interlocking, and PLC feedback in conveyor systems, pumps, and compressors.
