ABB’s Low-Voltage Division Introduces New Surge Protectors


ABB's low-voltage products division has released new UL 1449 3rd Edition-certified OVR DIN Rail surge protective devices (SPDs), which the company says are designed to protect equipment from damage caused by transient surges from lightning strikes, as well as by surges from upstream equipment and utility load switching.

The new OVR DIN Rail SPDs are approved as UL Type 4-recognized components and are usable in Type 2 applications, covering permanently connected SPDs intended for installation on the load side of the service equipment overcurrent device. The new product range utilizes fast-acting metal oxide varistors to limit overvoltage to values compatible with the sensitive equipment connected to the network, according to ABB.

Target applications include solar and other renewable energy installations, as well as other applications. The SPDs are available for most service voltages up to 600 V AC and come in two protection levels – 15 kA and 40 kA per phase (Imax).
