The 45 mm width is the S0 standard — you can gang them side-by-side without a gap, which matters when you're packing three contactors and a thermal overload into a 400 mm wide panel. The AC-3e rating at 690 V is the motor-switching spec you care about — it's the contactor's ability to handle the inrush and break the running current of a squirrel-cage motor. At 400 V it manages 23 kW, which covers a 30 kW motor with some headroom, or a 22 kW motor comfortably. Switching frequency maxes at 1 000 cycles per hour for AC-3 duty, dropping to 300 for AC-4 (plugging/inching) — that's about one start every 3.6 seconds, plenty for a conveyor or pump station. The substance prohibition date of May 1, 2012 confirms RoHS compliance per EU Directive 2011/65/EU. No UL or CSA mark is listed in the spec record, so if your panel requires a UL 508 listing, verify the specific variant or check the full datasheet for agency approvals on this order code.","metaTitle":"Siemens 3RT6024-1BM40 SIRIUS Power Contactor, S0, 23 kW at 4","metaDescription":"Siemens 3RT6024-1BM40 SIRIUS power contactor, Size S0, 23 kW at 400 V AC-3e.
