Siemens SIRIUS Innovation Contactor Relay, 3NO/1NC, 10A Contact Rating - 3RH2 Series - 3RH2131-1BB40
Need a reliable contactor relay for damping opening surges? This four-pole contactor relay from Siemens' SIRIUS Innovation range offers you the reassurance of effective overload protection to prevent damage to electric motor windings and coils. You can use it with solid-state circuits that have currents above 1mA at voltages over 17V. This device can be easily plugged onto all contactor relays to suppress the opening surge in the coil, allowing you to start electric motors without risk of damage.
• Operating temperature range of -25°C to +60 °C for efficiency in tough industrial environments
• Screw terminals to make secure connections quickly
• 24V DC coil voltage for resistance to the control circuit drop caused by high inrush
• IP20 (ingress protection) rating means it'stouch-proof and resistant to dust or objects larger than 12mm

What is overload in electric motors?
Overload is when a motor draws a current higher than it's rated for over an extended period. It's also known as overcurrent and is one of the main causes of failure in electric motors.
