The Hobut SHB200A60-CLASS 1 is an intelligent, solid-state, AC/DC four-pole combination protection relay for earth leakage/fault/overload current detection, trip preventing, and motor control applications. It offers a high level of accuracy and reactivity to ground fault conditions, and can effectively detect earth faults of low magnitude (<1A). It has two separate trip circuits, one for the main circuit and one for the ground circuit, helping to ensure effective protection from ground fault conditions. The relay also provides a variety of control functions, including pre-trip warning, under-voltage, over-voltage and voltage balance adjustment, phase-loss/failure, phase-sequence/ reverse, manual/automatic resetting, repeater/indication, etc. This relay also offers a digital display of all relay operations, as well as a remote monitor/control option.
