Description

Electronic earth leakage residual current protection and monitoring relay (Type B)

• Description
Electronic earth leakage current protection and monitoring relay (IEC 62020) compatible with the protection transformers
of the WGC-TB series. The RGU-10B is the most complete system for monitoring and controlling electrical insulation of
type-B installations (IEC 60755).

— Electronic relay with relay output.
— Measures in AC, DC or mixed current, type B (IEC 60755)
— Measures the intensity of the current by connecting to an earth leakage transformer of the WGC-TB series.
— Programmable with backlit LCD display:
1.Trip current (red display when tripped)
2.Parameter programming
2.Instantaneous leakage current
4.Disconnection of external transformer
— Status signalling via 2 LEDs
— Features two independent programmable outputs (main and prealarm).
— Includes a remote-control input.
— Assembly on DIN 46277 rail (EN 50022), 3 modules.

• Applications
Monitoring of electrical insulation in:
— single-phase or three-phase AC installations, AC installations with DC components or purely DC installations.
With frequencies of up to 1 kHz. Such as, for example:
— Speed drives
— UPS (Uninterruptible Power Supply systems)
— Photovoltaic installations
— Motor control devices, etc.
