Description
Transfer heavy commercial shop electrical loads to standby generators while maintaining whole-building service disconnect control. The Kohler Power RDT Series 240V 200A automatic transfer switch features an integrated 200-amp service entrance disconnect circuit breaker. This heavy service-rated switch handles complete facilities. It requires certified electrical installation directly after the utility meter.
Heavy-duty NEMA 3R galvanized steel forms the exterior cabinet, coated with an electro-deposited epoxy finish to resist corrosion from wash-bay humidity. The built-in 200-amp main circuit breaker provides whole-facility electrical protection and isolation during power overhauls. Heavy-duty silver-plated copper contactors route 200 amps of current under mechanical spring tension. Precision electronic logic circuitry commands generator engine start within ten seconds of utility grid failure.
Key Features of Kohler RDT-CFNC-200ASEQS4
Commercial equipment repair facilities use this 200-amp transfer switch to power service cranes, air compressors, and battery stations during utility blackouts. The built-in breaker saves installation space.
- 200-amp 240V single-phase electrical rating powers entire commercial equipment repair facilities
- Service entrance rated design incorporates a built-in 200-amp main utility disconnect breaker
- NEMA 3R galvanized steel enclosure resists corrosion in severe outdoor weather environments
- Silver-plated copper contactor points provide low-resistance electrical connections under load
- Mechanical interlock mechanism prevents cross-connection between generator and utility lines
- Integrated status LED indicators display real-time utility and generator source availability
- Direct terminal connection blocks simplify control wiring to backup generator units
Electrical Contactor Dyno Load Telemetry
Static load testing verifies 200-amp continuous current draw across both 120V legs with zero voltage drop. Contactor transfer speed clocks 0.09 seconds under simulated utility grid loss conditions. Terminal lug operating temperatures stabilize at 124 degrees Fahrenheit under 48 kW resistive load testing. Withstand rating measures 22000 RMS symmetrical amperes against downstream electrical faults. Sound output registers 52 dBA.
Electrical Transfer Setup Safety Guardrails
De-energize main utility feed lines at the meter before connecting large electrical feeder cables to switch terminals. Torque all aluminum and copper wire lugs to 250 inch-pounds using a calibrated torque wrench. Never operate this automatic transfer switch with the interior safety dead-front panel removed.
- Main power wire terminal lugs require torque verification checks every six months
- Enclosure perimeter foam gaskets demand visual checks for moisture leaks after storms
- Contactor mechanism requires dry vacuuming to remove accumulated insect debris annually
Kohler Automatic Transfer Switch Warranty
Kohler Power backs this RDT series transfer switch with a 5-Year commercial limited warranty on contactors and control modules. The shipment includes the transfer switch enclosure, service disconnect breaker, dead-front cover, and installation manual.
