The contactor carries a substance prohibitance date of 05/01/2012, indicating RoHS compliance from that date forward. For UL or IEC certification documentation, the brand provides it on request as part of the standard SIRIUS technical documentation package. The AC-3 rated voltage maximum of 690 V means this contactor can switch motor loads at line voltages up to that level, covering 400 V and 690 V industrial networks. At 400 V, the motor rating is 10.5 kW at 60 °C ambient; at 690 V it reaches 18 kW — the higher voltage allows the same current to deliver more power. The control circuit uses screw-type terminals, accepting 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) solid or stranded conductors — common for panel wiring. The main circuit terminals accept up to 2x 4 mm², or 2x 12 AWG, which covers the typical feed for a size S00 contactor. ## Mechanical endurance and switching frequency The contactor has a typical mechanical life of 30,000,000 operations, which is high for a size S00 frame. Maximum switching frequency at AC-3 is 750 1/h, at DC it is 10 000 1/h — the DC figure applies to the coil, not the main contacts, so a PLC output driving the coil can cycle it rapidly without wear concerns.","metaTitle":"Siemens 3RT6015-1BW42 SIRIUS Power Contactor, S00, 48 VDC, 6","metaDescription":"Siemens SIRIUS 3RT6015-1BW42 power contactor, size S00, 48 VDC coil, 6 A at 24 VDC.
