Reclosing protection relays and residual current reclosing with WGC external transformer

Description

Electronic residual current protection relay, used to connect the external toroidal transformers of the WG / WGS / WGC Series. Self-reclosing with a programmable residual current trip. Superimmunized type A Relay, with high frequency current filtering and high immunity. Monitoring in TRMS The backlight display shows the following information:

• Adjustment values
• Instantaneous leakage current

• Trip relay
• End-of-reclosing-sequence interlocking relay

• External input for remote control functions (230 V~)
• Automatic test of the connection and external transformer status
• Optional RS-485 Communications: type RGU-10C RAL
• Reduced dimensions: 3 modules
• Assembly on DIN rail 46277 (EN 50022).
• Optional assembly on 72 x 72 panel with accessory M5ZZF1.

Applications

The RGU-10 RAL relays associated to a meter allow the automatic reclosing after a trigger, thus offering the most adequate solution for public lighting, cash machines, refrigeration chambers, traffic lights, etc. Its design characteristics guarantee maximum security and continuity of the electrical service, avoiding unwanted tripping.
