M50ASR325 - 400 Amp Panel Switch

M50ASR325 - 400 Amp Panel Switch

The M50ASR325 is a 3-pole, 400-amp fusible panel switch with a bolt-in Type M50 design for your electrical distribution systems, rated up to 600 volts AC. It accepts Class RK1 and Class RK5 fuses and is intended for use in compatible panel switch assemblies.

When replacing electrical components, matching the original specifications is often more important than anything else. This panel switch offers the same basic configuration as many existing installations, including the correct pole count, amperage and voltage ratings, and bolt-in mounting style. That helps you simplify maintenance by allowing the existing equipment layout to remain unchanged.

The M50ASR325 is commonly used anywhere fused disconnecting means are required, from manufacturing facilities and warehouses to commercial buildings and institutional properties. Built to last, it serves as a practical, fit-for-purpose replacement for compatible equipment while helping you maintain the original design of the electrical distribution system.
