The coil hold range is 0.85 to 1.85 times the rated supply voltage — so it stays pulled in through a sag down to about 20.4 V and won't drop out until voltage falls well below that. Screw terminals and upright mounting position are standard for this frame; it snaps onto DIN rail and fits the same panel footprint as the S00 contactors it couples with.","metaTitle":"Siemens 3RH2131-1VB40-1AA0 Coupling Contactor Relay, 24 V DC","metaDescription":"Siemens 3RH2131-1VB40-1AA0 coupling contactor relay, 24 V DC, 3 NO + 1 NC contacts, integrated diode, Size S00.
