Single-phase starting current limiters

ESBN-S

Starting current limiters are voltage-controlled devices. Their functioning is based on a time-delayed bridging of the incorporated damping resistor (NTC) which is set ex works. Plastic casing, can be snapped onto mounting rail TS 35.

Note:
Starting current limiters are voltage-controlled devices. Their functioning is based on a time-delayed bridging of the incorporated damping resistor (NTC) which is set ex works. Plastic casing, can be snapped onto mounting rail TS 35.
Options:
Time delay can be switched over in 2 steps. Damping can be changed in 2 steps according to connection. Application: Limitation of starting currents in electrical devices, e.g. transformers, electric motors, etc. The starting current limiter is connected directly in series to a device which is exposed to a high starting current. Design: The ESBN-S type is constructed for a nominal current of 25 A. Caution: Due to the incorporated overtemperature protection, the starting current limiter requires a certain cooling down phase between the switching cycles. The time between two switching cycles should be approx. one minute. For the ESBN-S model to continue limiting operation, it is required that the voltage value first drops to zero.
