Key Features

• Correct Electrical Rating — Rated at 100 amps across 3 poles, matching the load-switching demands of the original circuit without over- or under-specifying the breaker capacity.
• NEMA3R Weatherproof Enclosure — The NEMA3R-rated housing protects internal switching contacts from rain, sleet, and external ice formation, keeping the transfer switch operational in outdoor installations.
• Automatic Transfer Operation — Switches power source automatically on utility loss, restoring connected loads without manual intervention and maintaining continuity of critical power supply.
• Genuine OEM Component — Manufactured to Multiquip's exact specifications, ensuring the switching mechanism, terminal configuration, and contact ratings align with the original equipment design.
• Confirmed NEMA3R Equipment Fitment — Verified for use on Multiquip NEMA3R-designated equipment, so you can order with confidence that this part is the right part for your application.
• Electrical Safety Compliance — A correctly rated transfer switch prevents backfeed hazards and overload conditions — critical for both operator safety and protection of connected loads during power transitions.

An automatic transfer switch monitors incoming utility power and, when it detects an outage or voltage drop, automatically disconnects the load from the utility and connects it to the standby power source — all without operator input. The 3-pole configuration allows it to switch all three legs of a three-phase or multi-wire circuit simultaneously, maintaining balanced power delivery. When a transfer switch fails, the result can be a complete loss of automatic changeover capability, leaving critical loads without power or, more dangerously, creating a backfeed condition on utility lines — making prompt replacement with the correct OEM part essential.
