Surge protection

MTL LS range LED surge protector

The Crouse-Hinds series MTL LS range is a versatile, high-performance, surge protection devices for use in a wide variety of equipment in industrial and commercial applications.  The MTL LS range is available in a variety of different voltage levels and surge ratings for wide range of applications.

The fast-acting circuitry will protect equipment from damaging electrical transients and disturbances. Fully automatic in operation, the LS range reacts immediately, clamping voltage surges without causing undue leakage losses under normal operation. No operator intervention is required as they reset automatically and are completely maintenance free.

Series and parallel versions are available. Series models automatically disconnect power to the load under fault conditions, while parallel devices are parallel-connected and disconnect themselves from the load under fault conditions, leaving power to the load.

The space savings footprint allow the LS range to be mounted in confined locations while providing protection the Line/Neutral, Line/Ground, and Neutral/Ground modes. The LS range is also a UL1449 4th Edition Recognised Component. With ingress protection to IP66 (NEMA 4X) the LS range can be installed in most locations and carries an unrivalled “no fuss” 10-year manufacturer’s warranty.
