The coil accepts 20-33 V AC/DC, 50/60 Hz, with an integrated varistor for suppression, so you can wire it directly to a 24 VDC control supply without adding an external snubber. ## Termination and auxiliary contacts — wiring constraints Main circuit uses screw terminals; the control circuit and auxiliary contacts use spring-loaded terminals. That mix matters for panel assembly: power wiring gets the torque-able screw clamp, while the coil and aux wiring snap in without a screwdriver — speeds up control-wiring termination on a DIN-rail panel. The built-in auxiliary contacts are 1 NO + 1 NC, enough for a feedback loop or a status light without adding a side-mount block. RoHS compliant since October 2014, with a REACH Article 33 notification for lead (CAS 7439-92-1) above 0.1% w/w.","metaTitle":"Siemens 3RT2037-3NB30-Z W96 Power Contactor, 65 A, 30 kW, 3-","metaDescription":"Siemens 3RT2037-3NB30-Z W96 power contactor, AC-3e/AC-3 65 A, 30 kW / 400 V, 3-pole, 20-33 V AC/DC coil, 1 NO+1 NC aux, spring-loaded control terminals.
