Siemens 3-Pole Contactor, 7A, 3kW - SIRIUS Series - 3RT2015-1BB41 Easily make or break the connection between your equipment and power supply with this robust 3-pole contactor from Siemens. The switch is electrically controlled and is powered at a lower level than the switched circuit, making it highly energy-efficient. Integrated fuses are on hand to provide protection from overcurrent and short circuits for improved electrical safety. THe unit also has an impulse voltage resistance of 6kV, allowing it to withstand voltage spikes. Thanks to a snap-on mounting system, this component is simple to install on DIN rails. You'll find it commonly used to control electric motors. • Power rating of 3kW for use in heavy-duty industrial applications
• Silver-alloy contacts for reliable conductivity and resistance to corrosion
• Flexible mounting positions with up to 180° rotation to suit the specifications of your machine
• Minimal power loss of 4W for improved energy efficiency
• Robust thermoplastic construction for impact and wear resistance What's the advantage of using a contactor rather than a relay? A contactor can carry higher current loads than a relay, making it suitable for more demanding electrical applications.
