The 50/60 Hz coil tolerance (0.8–1.1 at 50 Hz, 0.85–1.1 at 60 Hz) means it holds in on brownout conditions down to 80% of nominal at 50 Hz. Main circuit terminals accept solid or stranded conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²) for the smaller range, and 2x (1–2.5 mm²), 2x (2.5–6 mm²), max 2x 10 mm² for the larger. AWG equivalents: 2x (16–12), 2x (14–10), 1x 8. These ratings cover common control and power wiring sizes used in European and North American panels. Side-by-side mounting is permitted (zero gap), saving rail space. The 45 mm width and 85 mm height keep the footprint compact for dense panel layouts. Depth is 91 mm — enough to clear the terminals and arc chamber but standard for the S0 frame. For Type 2 coordination (limited weld risk, no damage), use gL/gG 25 A. These values assume a prospective fault current typical of industrial distribution.","metaTitle":"Siemens 3RT1024-1AL20-ZW97 SIRIUS Power Contactor, 12.5 A AC","metaDescription":"Siemens SIRIUS 3RT1024-1AL20-ZW97 power contactor, Size S0, 12.5 A AC-4 at 400 V, 7.5 kW at 500/690 V.
