Activation current limiter ISMET

Activation current limiter. Gentle start-up for one-phase and three-phase electrical consumers.

High activation currents, e.g. for start-up of electric motors, can damage or interfere with the supply network and other connected consumers. Voltage-controlled activation current limiters prevent heavy choking of the mains voltage and overloading due to current peaks. The activation current limiter works with a pre-adjusted limiting resistor (NTC) which reduces the activation current so that the consumer starts up more slowly. After a defined time delay, the NTC of the activation current limiter is bypassed automatically and the full output is available. ISMET delivers activation current limiters in several designs for various application and installation variants.

ESB Single-phase starting current limiters Starting current limiters are voltage-controlled devices.
