It mounts on a 35 mm DIN rail per EN 50022 using either screws or the snap-on mechanism, so it drops into a standard panel footprint without adapters. The coil is wound for 24 V at 50 Hz, drawing 10 A inrush at that voltage. That's a common control voltage for PLC-driven panels, but make sure your transformer is sized for the inrush — the holding current settles lower, but the pick-up surge is what trips undersized supplies. Rated motor power is 7.5 kW at both 500 V and 690 V, and 5.5 kW in AC-2 duty at 400 V. For the heavy inching or reversing jobs — AC-4 duty — the current limit is 12.5 A at 400 V. That's the number to watch if your application does frequent plugging or jogging; the AC-3 rating isn't listed here, so the AC-4 figure is the one that governs for severe switching. It's rated for a pollution degree of 3, meaning it's suited for industrial environments where conductive dust or condensation is present. The front face carries IP20 protection — finger-safe — while the terminal area is IP00, so it's meant to live inside a closed panel, not out in the weather. ## Environmental range Operating temperature spans -25 °C to +60 °C, which covers most indoor industrial environments from unheated warehouses to warm cabinet interiors. Maximum operating altitude is 2 000 m — standard for gear not specially derated for high-altitude installation. Mechanical endurance is quoted at 10 million operations typical. That's a long service life for a contactor in normal motor-starting duty; the electrical endurance will be lower and depends on the switching current and load type.","metaTitle":"Siemens 3RT1024-1AB00-ZW98 SIRIUS Power Contactor, S0, 24 VA","metaDescription":"Siemens SIRIUS 3RT1024-1AB00-ZW98 power contactor.
