The 24 V AC 50 Hz coil is frequency-specific; a 60 Hz supply will change coil impedance and may cause dropout or overheating, so verify your control transformer matches 50 Hz. ## Terminal configuration to note Main circuit uses screw terminals, while the control and auxiliary circuit uses spring-loaded (cage-clamp) terminals. That split means the power wiring gets a traditional screw clamp — fine for lugs or ring terminals — but the coil and aux wiring needs a ferrule or solid conductor for the spring cage. Strip length and wire gauge for the spring side follow the standard 0.25–2.5 mm² range for SIRIUS aux terminals. ## Panel integration The 122.5 x 62 x 142 mm envelope fits alongside other SIRIUS S2 devices — contactors, overload relays, soft starters — on the same rail. Auxiliary contact block (1 NO + 1 NC) is built in; additional front- or side-mount aux blocks can be added without losing DIN space.","metaTitle":"Siemens 3RT2037-3AB00-Z W96 Power Contactor, 65 A AC-3, 24 V","metaDescription":"Siemens SIRIUS 3RT2037-3AB00-Z W96 power contactor, AC-3e/AC-3 rated 65 A, 30 kW at 400 V. 24 VAC 50 Hz coil, 1 NO+1 NC aux.
