Siemens 3RT2 Control Relay 3NO, 22 A F.L.C, 40 A Contact Rating, 230 Vac, 3P, SIRIUS

Protect your switching contactor and connected motor circuit with this overload control relay from Siemens. It breaks a connected circuit when it's exposed to excess current or heat. This prevents overheating, which could damage a motor's coils and windings, potentially leading to device failure. You can use this unit to open and close contactors in Siemens' 3RT range. It's part of Siemen's SIRIUS modular system of components for starting and protecting industrial motors up to 250kW/400V AC, so you know it's a trusty choice for your high-load applications. With a rated surge voltage resistance of 6kV, it takes the sting out of significant electrical spikes.

• IP20-rated, so you can trust its terminals and body pose no shock risk
• Works up to 2000m above sea level, so is suitable for high-altitude locations
• Operating temperature range of -25°C to +60°C for compatibility with harsh environments
• Three poles let it control up to three motors simultaneously
• Simply snaps onto a 35mm DIN rail for easy mounting

The relay takes up to 16ms to open and up to 40ms to close, so you can count on super-fast switching action.
