This 4-pole, 5-wire assembly includes prewired auxiliary contacts rated at 5A for 277VAC and 0.3A for 125VDC, simplifying field installation with 36-inch leads (reference DEH-40324 for color coding). Designed for compatibility with MaxGard receptacles and inlets, it supports wiring from 2 AWG up to 350 MCM, with options to accommodate 500 MCM cable via reducing adapters (e.g., PT500R350-3). The assembly features a standard locking pawl to prevent accidental disconnections under load, meeting UL 1682 and CSA 182.1 certifications. It operates safely across a temperature range of -40°F to 140°F and carries a short-circuit withstand rating of 18 kA when tested with RK1 current-limiting fuses sized at 100% of the device’s ampacity. Type 4X/IP69/IP69K environmental ratings ensure reliable performance in harsh industrial environments, including those requiring IP66/IP67 compliance. This interior assembly is engineered specifically for MaxGard female applications, providing a durable and UL-listed solution for power distribution systems.
