Description
5 Pole 100A Auto Reset Device with PME Fault Protection
Whitecliffe Electrical WARB5100C
The Whitecliffe WARB5100C 5-pole 100A auto reset device provides dependable PME fault protection for three-phase systems. It continuously monitors supply voltage and disconnects live, neutral, and earth when an under-voltage or over-voltage fault is detected, ensuring safe operation at all times.
Rated at 100A, it delivers strong protection while remaining easy to operate. However, to enhance safety, it requires a manual reset after over-voltage events, while under-voltage conditions reset automatically once supply returns to normal.
In addition, the WARB5100C includes overload and short-circuit protection, reducing the need for additional devices. As a result, it simplifies system design and improves overall reliability. Installation is straightforward, since no earth electrodes are required, making it ideal for both new and retrofit projects.
