Instrument Xfrms PRiMA Auxiliary Relays

Plug-in Rapid-wire Integrated Multi-mount Auxiliary Relays for Electrical Substations

• PRiMA is a compact, voltage operated, attracted armature auxiliary relay with instantaneous and time delayed auxiliary functions.
• PRiMA is designed to satisfy the needs for contact multiplication in protection and control environments and was developed as a result of worldwide market studies.
• PRiMA relays are ruggedised and specifically designed for operation and to be part of large scale electrical fixed installations, where robustness, reliability and compliance with substation norms are paramount.
• Ease of installation is ensured thanks to the two-part design in which the relay plugs into a socket which may be specified with front or rear connected terminals.
• A snaplock feature between relay and socket eliminates the need for separate wire clips.
• The front-connected socket, mainly for DIN rail mounting, may alternatively be mounted on a solid panel via a single fixing screw, whilst the rear-connected design clips or screw can be fixed to suitable panel cut-outs or to a special rack mounting frame.
• Wide operative voltage range
• Manufactured from flame-retardant materials
• Compact design - 12 relays per 19 inch rack
• Built-in snap lock feature automatically locks the relay to its socket
• Simple mechanical coding for relay to socket connections
