The 230 V AC 50/60 Hz coil is a common control voltage in European panels; the built-in 1 NO + 1 NC auxiliary contact set handles feedback or interlocking without an extra block. Termination is split: screw terminals on the main circuit for high-current power wiring, spring-loaded terminals on the control and auxiliary circuit for faster, vibration-resistant wiring of the coil and aux contacts. This combination is typical on Siemens S2 contactors — the spring-cage side saves time on control wiring while the power side keeps the torque security of screw clamps. RoHS compliance is confirmed since October 2014, and REACH candidate-list information is available from Siemens. No special export restrictions apply (AL: N / ECCN: N). The S2 frame size mounts on a standard DIN rail (EN 60715) and occupies roughly 55 mm width by 114 mm height by 130 mm depth. The multi-unit packaging variant (pack of 15) suggests it is also stocked in bulk for panel builders running multiple identical motor starters. The spring-loaded control terminals accept ferruled stranded wire up to 2.5 mm²; strip length is 8–10 mm for reliable cage clamping.","metaTitle":"Siemens 3RT2037-3AL20-Z W96 Power Contactor, 65 A, 30 kW / 4","metaDescription":"Siemens 3RT2037-3AL20-Z W96 power contactor, AC-3e/AC-3 rated 65 A, 30 kW / 400 V, 3-pole, 230 V AC coil, 1 NO + 1 NC aux, screw main / spring-loaded control terminals, size S2.
