Type 1 coordination allows a 63 A gL/gG fuse upstream; Type 2 coordination requires a 25 A gL/gG fuse to limit let-through energy and protect the contactor from weld damage during a short circuit. ## Coil and auxiliary contact ratings The built-in varistor suppresses the coil surge at dropout — no external snubber needed for the 24 V DC coil. The auxiliary contact block is rated 10 A at 24 V DC (AC-12), 6 A at 230 V, and derates to 0.3 A at 220 V DC and 0.2 A at 60 V DC. These ratings govern the pilot duty load the auxiliary contacts can switch — a PLC digital output or a relay coil, for instance — and the DC curve drops fast because DC arcs sustain longer than AC. ## Wiring and panel fit The screw terminals accept solid or stranded conductors: 2x (0.5–1.5 mm²) or 2x (0.75–2.5 mm²) for the auxiliary circuit, and 2x (1–2.5 mm²) or 2x (2.5–6 mm²) for the main circuit, with a maximum of 2x 10 mm². AWG equivalents are 2x (16–12) and 2x (14–10) for the main contacts. The contactor footprint is 45 mm wide × 116 mm high × 101 mm deep — the 45 mm width is a standard 2.5-module DIN-rail slot, so it replaces an existing S0 contactor without re-drilling the backplate. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices for heat dissipation.","metaTitle":"Siemens 3RT1024-1XP00-0GA0 SIRIUS Power Contactor, S0, 5.5 k","metaDescription":"Siemens SIRIUS 3RT1024-1XP00-0GA0 power contactor, size S0, 5.5 kW AC-2 at 400 V, 12.5 A AC-4.

It will not drop into a panel wired for the S0 frame without changing the mounting rail and re-terminating the conductors. The 3RT1024-1XP00-0GA0 is the correct S0-frame replacement for its own BOM line."},{"question":"What is 3RT1024-1XP00-0GA0's listed depth (101 mm) on this component line?","answer":"The depth is 101 mm, measured from the mounting surface to the front of the contactor housing. That dimension fits standard 200 mm deep enclosures with room for wiring gutters."},{"question":"Will 3RT1024-1XP00-0GA0 drop into a panel that was specified around 3RT1023-1AL20 without rewiring?","answer":"No — the 3RT1023-1AL20 is an S00-frame contactor (45 mm wide but shorter height and different mounting hole pattern).
