Phase sequence monitoring relay SLU-100 series

phase unbalancethree-phaseDIN rail

The SLU-100 series consists of various universal motor relays that were designed to provide a cost-effective protection solution against premature failure for various equipment, as well as against downtime that may be caused by voltage faults or untimely outages in three-phase systems. The items are designed to support the systems typically found in motor control centers and critical motors, or applications of a pump monitoring type. The products are also designed for the convenience of electricians, engineers and maintenance managers, with the series being able to monitor up to 480VAC. The easy adjustment capabilities, imbalance percentage and fault delay time are also worth mentioning. Note that these capabilities allow for high reliability protection, no matter what regenerative voltages may be present in the system. Each item in the series comes with a LED fault indicator at the same time, allowing visual troubleshooting.
