ABB Monitoring Relay, 6A Rated Switching Current, Single Pole - CM-UFD Series - 1SVR560730R3401 CM-UFD.M31
Protect your industrial equipment from damage caused by voltage spikes with this monitoring relay from ABB. It surveys the voltage range of connected devices and trips the circuit breaker it's paired with when the voltage falls outside the preset range. The unit's housing resists impact and corrosion, so you can rely on it for safe use in harsh environments. For optimal security, the device can be password protected to prevent the set parameters from being tampered with by unauthorised personnel. Thanks to screw termination, you can install this relay easily with just a simple screwdriver.
