The Kohler RXT JFNC ASEQS3 400 Amp Automatic Transfer Switch provides high-capacity, heavy-duty emergency power control for large residential and whole house standby applications. Part of the advanced RXT series, this service entrance rated switch is specifically engineered to operate exclusively with single-phase Kohler generators equipped with advanced RDC2 or DC2 controls, monitoring utility grid lines 24/7 to automatically transition major electrical loads the moment utility power fails.

Engineered as a highly efficient 2-Pole 3-Wire Switch for 240V Single Phase Systems, this emergency assembly features an integrated utility disconnect on the service entrance side. It includes an RXT single phase combined interface and load management board, enabling smart load shedding capabilities with automated load control time delays to systematically manage and prioritize critical household circuits while protecting the backup generator system from temporary overload conditions.

Built for exceptional field longevity and superior environmental protection, the internal mechanical contactor is safely housed inside a rugged, corrosion-resistant aluminum enclosure certified for stable indoor or outdoor installations. Featuring silver alloy main contacts and optional support for external LED status or module indicators, this premium US-built transfer switch ensures whisper-quiet standby performance, backed by a 5-year, 2000-hour limited warranty.
