Vigi C120 Residual Current Protective Unit Manual

The Vigi C120 is an electromagnetic residual current protective unit designed for use with 2‑, 3‑ or 4‑pole circuit breakers rated 63‑125 A. It offers instantaneous (瞬动型) tripping, selective coordination, and AC‑type protection for both indirect and direct human contact as well as equipment insulation faults.

The manual lists technical parameters such as rated current (<125 A), residual current settings (30‑500 mA), frequency (50/60 Hz), operating temperature (‑5 °C to +60 °C), and physical dimensions. Wiring guidelines specify soft‑cable sizes of 1.5‑35 mm² and hard‑cable sizes of 1‑50 mm², with module widths expressed in multiples of 9 mm for different pole configurations. This manual is written in Chinese.
