Siemens SIRIUS 3RT Size S2, 3RT2 Contactor, 110 V ac Coil, 3-Pole, 80 A, 30 kW, 3NO, 690 V ac

Keep your motors running smoothly with this 80A contactor from Siemens. It has a power rating of 30kW and a contact voltage rating of 690V AC. This makes it ideal for switching heavy industrial loads to control motors in equipment such as conveyor systems, pumps and fans. The device is fitted with two auxiliary contacts to give you extra functionality, meaning you can set up remote control or parallel operation, for example.

• Operating temperature range of -25°C to +60°C makes it suitable for use in harsh industrial environments
• Screw terminals achieve quick and easy electrical connections
• 3PST configuration is suitable for switching circuits on and off in demanding industrial three-phase systems
• DIN rail mounting helps you quickly build an organised and compact electrical system

A three-phase system uses three AC voltages of equal frequency but with a phase difference of 120˚ to distribute power. This delivers balanced, constant and efficient power transmission, which is ideal for operating electric motors. For these reasons, three-phase electrical systems are commonly used for industrial machinery.
