Surge protective device

Finalist in Electrical Distribution in Consulting-Specifying Engineer's 2011 Product of the Year competition

05/09/2011


The Liebert SH Hybrid Series surge protective device from Emerson Network Power is a hybrid product with a coordinated multistage system of suppression. It uses a transitional method that includes a silicone avalanche diode module with tight clamping and rapid response. There is also a secondary metal oxide varistor module for high-energy capacity. This is made possible with an impedance-matching network with controlled copper geometries. The series offers component-level monitoring, including neutral to ground. It has a sand-packed silver fuse network that is UL-rated at 200 kA interrupting capacity. All of the product’s surge suppression components are computer-tested.
