Siemens 3RT2 Series Contactor, 110 V ac Coil, 3-Pole, 7 A, 3 kW, 3NO, 400 V ac

This contactor from Siemens switches electrical circuits on and off to ensure your commercial and industrial applications run smoothly. The 3-pole electrically controlled switching device is particularly suitable for higher-current-carrying devices where standard relays can't handle the loads. By repeatedly and rapidly opening and closing contacts, it manages arc suppression to interrupt heavy motor currents with minimal damage to prolong the lifespan of your equipment. You can use the unit in temperatures varying from -25°C to +60°C, which means it's suitable for harsh conditions and heavy-duty applications. This versatile component controls light switches, electromagnets and industrial motors.

• Ingress protection rating of IP20 indicates the unit is touch-proof, so enhances safety by preventing electric shocks
• Screw termination fastens contacts securely for reliable signal transfers in impact-prone environments
• DIN-rail mounting capability for ordered and space-saving assemblies
• Compact dimensions of 57.5mm (length), 45mm (width) and 73mm (depth) make it easy to install in tight spaces

Both contactors and relays switch circuits on and off. A contactor is a specific type of relay that has the ability to switch high amounts of current.
