This pre-matched set saves panel build time and eliminates coordination errors between the contactor and overload relay. ## AC-3 duty and Class 10 trip — what they mean for motor protection The same 65 A rating applies under AC-3e at 400 V, which covers the enhanced electrical endurance test for frequent switching applications. This is the standard protection for standard-start motors — it allows the inrush during acceleration while still protecting the motor against a locked-rotor condition. At 480 V the rated current is 65 A; at 600 V it derates to 52 A. ## Panel integration — DIN rail and clearance Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm at the side, 10 mm downwards, and 0 mm backwards. The zero backward clearance means the unit can sit flush against the back panel or a busbar support, which is useful in dense layouts. Main circuit terminals are screw-type, sized for the S2 feeder current. The design is for standard rail or screw mounting, so it can also be bolted directly to a panel backplate if DIN rail is not available. ## Environmental and compliance Operating temperature range is -20 to +60 °C; storage and transport range is -50 to +80 °C. The temperature compensation for the thermal overload release matches the operating range, so the trip curve stays accurate across the full ambient span. Substance prohibitance date is 03/01/2017 — this aligns with the RoHS recast (EU 2015/863) compliance deadline. The starter is designed for standard rail or screw mounting.","metaTitle":"Siemens 3RA2150-4JA37-0AP0 SIRIUS Motor Starter, 65 A AC-3","metaDescription":"Siemens 3RA2150-4JA37-0AP0 SIRIUS direct-on-line motor starter, 65 A at 400 V AC-3, Class 10, 690 V max.
