ELEKTRA has expanded its range of switches by developing a new range of main switches with undervoltage release, known as the S series, available from NHP .

Automatic restart of machines can cause a dangerous situation, either with damage to the machine, work in progress or the operator of the machinery.

The automatic restart after a power failure or subsequent restoration of power can be safely avoided with the new Elektra S series main switches.

In the instance of a power failure, the undervoltage release coil returns the switch to the OFF position, preventing automatic start up of machinery upon restoration of the power supply.

The switches are available from 25 to 160 amps in both 240V coil and 415V coil models.
