The MT-SRG-T1SP-3PH-40KA-220Y.127-N4X offers electrical protection for heavy-duty equipment in industrial buildings. This surge protective device operates with three-phase 220Y/127V AC, 50/60Hz. Equipped with a Wyn-n 4-wire configuration, the unit caters to 40kA maximum surge current per phase and up to -30dB EMI/RFI. Diagnostic LEDs located at the front of the device indicate normal operating conditions, as well as fault conditions on L1, L2 and/or L3.
The industrial SPD is constructed of steel. A NEMA 4X rating provides protection against ingress of water, dust/debris, corrosion and external formation of ice. As a Type 1 surge protective device, the unit is designed for installation between the secondary side of the utility service transformer and the line side of the system's overcurrent protective device. Alternatively, operators may also install the SPD at the main service equipment (load side).
This surge protective device accommodates #12 AWG wire leads. Wiring passes through a 0.5" opening at the back side of the unit.
The MT-SRG-T1SP-3PH-40KA-220Y.127-N4X is compatible with surface mounting applications.
