The coil is rated for 110 V AC at 50/60 Hz, and the full rectifier is integrated into the unit — no external bridge needed for DC operation of the coil. ## Integration notes The S00 frame size snaps onto a 35 mm DIN rail per EN 60715, with a 45 mm width that leaves room for adjacent auxiliary contact blocks or overload relays in a motor starter stack. Cage clamp terminals accept 0.5–2.5 mm² conductors; strip length is 10 mm. The integrated full rectifier means the coil draws DC after the initial AC pick-up — verify the control transformer sizing if multiple relays pick up simultaneously.","metaTitle":"3RH1344-2GG20 Contactor Relay, 6NO+2NC, 110VAC, Cage Clamp,","metaDescription":"3RH1344-2GG20 contactor relay from Siemens: 6NO+2NC, 110V AC 50/60Hz, cage clamp connection, size S00 with full rectifier.
