The S00 frame occupies 45 mm width × 60 mm height × 73 mm depth — fits a standard 45 mm slot in a panel layout. Side-by-side mounting is permitted with no derating gap. Solid and stranded conductors: 2 × (0.25 … 2.5 mm²) for main contacts, 2 × (0.25 … 1.5 mm²) finely stranded with ferrule. AWG equivalents: 2 × (24 … 14) for both main and auxiliary contacts. ## Coil and surge suppression DC coil draws 2.3 W closing and holding — no power drop after pickup, so the supply must sustain that continuously. Built-in diode surge suppressor across the coil; verify polarity before energizing. Pollution degree 3 environment rated, IP20 on the front and terminals — suitable for clean, dry control cabinets only, not washdown areas.","metaTitle":"Siemens 3RT1015-2JB42-ZW96 SIRIUS Power Contactor, 24 VDC, 1","metaDescription":"Siemens SIRIUS 3RT1015-2JB42-ZW96 power contactor. 24 VDC coil, 15 A rated at 24 V, 3-pole, Cage Clamp terminals, S00 frame.

The key difference is termination: the -2JB42-ZW96 uses Cage Clamp terminals, while the -1BB42 uses screw terminals. Panel wiring change required if swapping between the two."},{"question":"Will 3RT1015-2JB42-ZW96 drop into a panel wired for 3RT1015-1BB42?","answer":"Mechanically yes — same S00 footprint, same 45 mm width, same DIN-rail clip. But the Cage Clamp terminals on the -2JB42-ZW96 require a different wiring preparation (no ferrule needed for solid, ferrule for stranded) versus the screw-clamp terminals on the -1BB42. The panel wiring will need re-termination, not just a swap."},{"question":"Where can I buy 3RT1015-2JB42-ZW96 and how is it quoted?","answer":"This part is sourced to order against an RFQ through independent industrial-automation distribution.
