MVAP 22
Voltage Selection/Fuse Failure Relays
The MVAP 22 is essentially a fuse failure relay with changeover output contacts enabling it’s use for either voltage selection or fuse failure protection. A typical application as a voltage selection relay is the automatic connection of metering equipment to an alternative supply if the normal or preferred supply fails. As a fuse failure relay, it will monitor the output of a voltage transformer and give an alarm or disconnect protection circuits for VT fuse failure.

PRiMA Plug-in Auxiliary Relays
PRiMA relays are ruggedized and specifically designed to be part of large scale electrical fixed installations, where robustness, reliability and compliance with substation norms are paramount. PRiMA auxiliaries are versatile plug-in relays with up to four pairs of output contacts. The space efficient design allows mounting in any location within a cubicle or panel, whether front or back of panel, DIN rail, etc. Typical applications are for general contact multiplication, interlocking, volts/no volts indication and other annunciation.
