This is a phased-out product, with the official successor being the SIRIUS 3RT2 series — meaning if you're maintaining a panel built around the 3RT1 frame, this coil is the correct drop-in for the existing contactor, but for new builds or full replacements, the 3RT2 family is the current-production path. ## What the 60 V DC rating means for fit The 60 V DC rated value is the coil's nominal operating voltage — it's what the magnet coil is designed to pull in and hold at. If your control circuit delivers 60 V DC, this coil will pick up reliably and stay sealed. The spring-loaded connection technology (cage clamp style) accepts solid or ferruled stranded wire without needing screwdriver torque; it's faster to terminate in a panel build and more vibration-resistant than screw terminals. Size S2 is the contactor frame size — this coil physically fits S2 contactors from the SIRIUS 3RT1 range.","metaTitle":"Siemens SIRIUS 3RT1934-5BE42 Magnet Coil, 60 V DC, Spring-Lo","metaDescription":"Siemens SIRIUS 3RT1934-5BE42 magnet coil for S2 contactors, 60 V DC, spring-loaded terminals.
