Functionality

The Siemens 3RT2926-1JK00 surge suppressor operates on the principle of a varistor (Voltage Dependent Resistor). Under normal operating conditions, the varistor has a very high resistance and does not interfere with the circuit.

When a voltage surge occurs, the varistor’s resistance dramatically decreases, effectively shunting the excess voltage away from the contactor’s coil and dissipating it as heat. The integrated LED provides a visual confirmation that the suppressor is functioning correctly, allowing technicians to quickly identify any potential issues.
