Key Features

• Genuine OEM Electrical Specification — Manufactured to Multiquip's exact current rating and switching tolerance, ensuring the 100-amp, 3-pole configuration performs as the system was engineered to demand.
• NEMA3R Enclosure Rating — Built for outdoor and weather-exposed installations, the NEMA3R rating provides protection against rain, sleet, and windblown debris — critical for generator transfer switch applications.
• Direct OEM Replacement — Replaces the original transfer switch unit on NEMA3R-configured Multiquip generator systems, connecting to existing wiring and mounting points without adaptation.
• Automatic Switching Function — Detects utility power loss and transfers the load to generator power automatically, restoring power delivery without manual intervention.
• Electrical Safety Compliance — As a genuine OEM component, this switch meets the safety and load-handling standards required for properly rated automatic transfer switch installations in generator systems.

An automatic transfer switch monitors incoming utility power and, upon detecting an outage or voltage drop, automatically disconnects the load from the utility source and connects it to a standby generator — all within seconds. The 3-pole, 100-amp configuration handles three-phase or multi-circuit load demands, making it suited for commercial and contractor-grade generator setups. A failed or worn transfer switch can result in failure to switch over during an outage, dangerous backfeed conditions, or intermittent power delivery, making timely replacement essential to safe system operation.
