Description
Keep landscape fleet operations running without interruption when severe weather knocks out grid power. The Kohler Power RDT Series 240V automatic transfer switch routes auxiliary power from standby generators into shop circuits within seconds. This 200 Amp service entrance rated switch protects battery charging benches, hydraulic lifts, and air compressor systems. It cannot switch three-phase commercial distribution panels.
The NEMA 3R corrosion-resistant aluminum enclosure protects internal contactors from wind-driven rain, ice accumulation, and fertilizer dust. Heavy silver-plated copper bus bars route 200 Amp continuous electrical loads without conductor heat buildup. A heavy-duty double-throw contactor mechanism shifts line feeds via high-torque solenoid actuation. Solid mechanical interlocks physically prevent simultaneous connection of utility and emergency generator power lines.
Automatic Transfer Switch Technical Specs
Fleet maintenance shops require dependable subpanel power routing to prevent lost labor hours during storm blackouts. This commercial switch delivers automated load isolation and generator connection.
- 200 Amp service entrance rating handles main electrical panel feeds for commercial shops
- 240-volt single-phase configuration connects standard split-phase utility line inputs
- NEMA 3R aluminum enclosure stops outdoor rust in high humidity coastal environments
- Heavy double-throw contactors shift electrical connections within 100 milliseconds
- Mechanical interlocking hardware prevents backfeeding emergency power into downed utility lines
- Microprocessor logic board monitors incoming grid lines for brownout voltage drops
- Silver-plated copper contact pads resist arc damage during inductive load switching
Contactor Load Bench Electrical Telemetry
Dynamometer load benches subject this switch to 200 Amp continuous resistive loads for four hours. Terminal bus temperature rise stabilizes at 39 degrees Fahrenheit above ambient room air. Sound meters record contactor actuation noise at 71 dBA at three feet distance. High-potential dielectric testing verifies contact isolation up to 2500 volts without phase arcing. Solenoid engagement pulls eight Amps inrush for 80 milliseconds during transfer before returning to zero continuous draw.
Installation Criteria Equipment Boundary Limits
Certified commercial electricians mount this aluminum enclosure between the outdoor electric meter and indoor breaker distribution panels. Maintenance staff check system status via exterior door indicator lamps. Do not install this switch on 480-volt industrial power networks.
- Main power lug set screws require torque checks to 250 inch-pounds every twelve months
- Internal contact pads require visual checks for carbon soot every hundred transfer cycles
- Enclosure door seals require silicone grease application before freezing winter weather
Warranty Details Transfer Switch Manifest
