The coil draws 3.3 W during closing and holds at 3.3 W DC — a fixed-gap magnetic circuit that stays at full power, no economizer. This matters for control-transformer sizing: the inrush is the same as the hold. ## Panel Integration — DIN Rail & Wiring Width is 45 mm, height 57.5 mm, depth 72 mm — standard S00 footprint. Terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and max 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. This covers common control and power wiring up to 4 mm² for the main circuit. The -ZW97 suffix denotes a special version. The base order code 3RT1015-1BB42 shares the same electrical ratings and physical footprint. RoHS compliance date is 01.07.2006. ## Coordination & Protection For type 1 coordination (welding allowed but no fire risk), the fuse is gL/gG 35 A. This guides the panel builder on branch-circuit protection sizing.","metaTitle":"Siemens 3RT1015-1BB42-ZW97 SIRIUS Power Contactor, 24 V DC C","metaDescription":"Siemens SIRIUS 3RT1015-1BB42-ZW97 power contactor, 24 V DC coil, size S00, 45 mm width, 72 mm depth, IP20, screw terminals, current production.
