SGR-2 Series Residual Current Circuit Breaker Life

Breaking time of residual current

Wiring (The suitable conductors should be used for connection,see table below for relative parameters)

Features When designing residual current devices, manufacturing technology and type of routine tests, the lEC / EN 61008-1 standards were considered.Important features are: Up to date design User-friendly connection of conductors and busbars Resistance to current surges; unwanted tripping excluded Simple and solid fixing to a 35 mm mounting rail in compliance with EN 60715 Additional colour display of main contacts position (red:contacts closed, green:contacts open) Overall and mounting dimensions
