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 40 mm-diameter MOV while the 75000 series uses 53 mm-diameter MOV.
