Our family of monitoring relays and controls include current monitors, voltage monitors, power monitors, phase loss relays, 3-phase monitors and current transformers.
These monitoring relay products are used in a wide range of applications for protecting motors against the damaging effects of single phasing and overloads.
Applications such as elevators, compressors (refrigeration equipment manufacturers!), pumps, HVAC systems and mixing systems.
