The coil picks up at 85% of rated voltage and drops out at 185% — meaning it releases reliably on a sagging 24 V bus, which matters when you're sequencing multiple contactors off a shared supply. The main contact ratings are given in AC-2 and AC-4 duty, which is what you need for slip-ring motor starting and plugging/inching respectively. At 400 V AC, it's rated for 5.5 kW in AC-2 and 8.5 A in AC-4. The AC-12 maximum operating current is 10 A — that's the resistive load ceiling, so for heater banks or ballast loads you're limited there. For motor power at higher voltages, it handles 5.5 kW at both 500 V and 690 V, meaning it's comfortable on 480 V and 600 V class systems without derating the power rating. The 45 mm width means it takes a single 45 mm slot in the rail — panel fill factor is easy to calculate. The main circuit uses spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded, or 2x (24 to 14 AWG). That's the same wire range as most terminal blocks in the panel, so you're not pulling odd wire sizes. ## Environmental and protection IP20 on the front and at the terminals — that's finger-safe but not washdown. The built-in varistor surge suppressor across the coil means you don't need to add a separate suppression diode or RC snubber — it's already there, handling the inductive kick when the coil de-energizes.","metaTitle":"Siemens SIRIUS 3RT1017-2WB41 Power Contactor, Size S00, 24 V","metaDescription":"Siemens SIRIUS 3RT1017-2WB41 S00 power contactor. 24 VDC coil, 10 A rated at 24 V.
