Coil operating range spans 0.8 to 1.1 × rated voltage at 50 Hz and 0.85 to 1.1 at 60 Hz, so it holds in during brownout conditions down to 80 % of nominal. IP20 on the front, IP00 at the terminals — the terminal area needs finger-safe shrouding if the panel door is open. Terminals accept 2x (0.25 to 2.5 mm²) solid or stranded, up to 2x 10 mm² max. AWG equivalents: 2x (16 to 12) or 1x 8. The spring-cage auxiliary terminals (if fitted) follow the same strip-length discipline — 8 mm avoids whiskers. This gives the panel builder clear headroom for selectivity with upstream motor protection. Mechanical endurance is typical 10 million operations — no-load switching life for applications like conveyor diverters or valve control where the main contacts rarely break current.","metaTitle":"Siemens 3RT1026-3AL20-ZW98 SIRIUS Power Contactor, S0, 11 kW","metaDescription":"Siemens SIRIUS 3RT1026-3AL20-ZW98 power contactor, size S0, rated 11 kW at 400 V AC-2, 15.5 A AC-4.
