Our selection of monitoring relays can be easily customized for specific application requirements. A few examples available features are fixed settings (with or without knobs), remote adjustments, special pin configurations or performing a specific time delay function. Our current monitoring relays are a reliable way to monitor AC single-phase currents for overcurrent or undercurrent conditions. They are suitable for control of machines and protection of mechanical apparatus overloading conditions that result in measurable increase in motor current. Ground fault monitoring relays are a family of digital electronic ground fault protection relays designed for industrial applications. These relays combine low cost with high accuracy to give reliable protection on resistance grounded and solidly grounded power distribution systems.
