Description

Leviton 74000/75000 series panel mounted surge protective devices provide seven-mode protection in 120/208 VAC and 277/480 VAC WYE-configured, 3-phase systems. These Type 2 devices are designed for installation at the service entrance, at branch panels, or as dedicated transient surge protection for critical equipment. Both series feature individually fused metal oxide varistor arrays; the 74000 series uses 40mm-diameter MOV while the 75000 series uses 53mm-diameter MOV.
