This is a standard industrial control voltage in many regions; the AC coil draw is specified for the 50 Hz line frequency, so verify compatibility if the installation runs on 60 Hz — the coil impedance changes with frequency and may affect pick-up and hold-in performance. ## Auxiliary contact ratings and wiring capacity These ratings cover typical PLC input sensing and control relay loads — the 24 V AC 10 A rating is generous for a feedback signal to a controller. This covers most control wiring gauges used in panels — 1.5 mm² for control circuits, 2.5 mm² for short power runs. The screw terminals are the same type as the main coil connection, so the same screwdriver and torque setting apply across all terminals. Up to two additional auxiliary contact blocks can be attached, expanding the switching capacity for multi-signal feedback or interlocking logic without adding a separate relay. ## Mounting, clearances, and environmental limits Side-by-side mounting is permitted, so multiple S2 contactors can be ganged without extra spacing — useful for multi-motor groups in a single panel section. The -40 °C low end covers cold storage or unheated plant areas; the +70 °C upper limit is typical for enclosed panels with moderate heat rise from other devices. ## Sourcing and lifecycle — current production, quoted to order No stock-holding claim is made — each order is quoted individually to ensure traceability and manufacturer warranty coverage.","metaTitle":"Siemens 3RT2337-1AP00 SIRIUS Contactor, S2 Size","metaDescription":"Siemens 3RT2337-1AP00 SIRIUS contactor, S2 size, 230 V AC 50 Hz coil, screw terminals, 1 NO + 1 NC main contacts, auxiliary switch included.
