Challenger D50373-16 Molded Case Switch

Challenger D50373-16 molded case switch is a 100 A, three-pole disconnect designed for 240 V AC service in three‑phase electrical systems. Housed in a rugged molded‑case enclosure, it provides a manual means to quickly isolate power for maintenance or emergency shutdown in industrial control panels and power‑distribution applications. The D50373-16 variant identifies a specific model within Challenger’s legacy lineup, offering a compact, durable solution where reliable interruption of load current is required in 240 V three‑phase setups. This molded‑case switch is intended for use in commercial and industrial environments where three‑phase power must be safely disconnected, and it pairs with other Challenger components in panel assemblies. As with any electrical installation, verify enclosure compatibility and conductor sizing, and follow applicable electrical codes during mounting and termination.
