Kohler RXT-100A-3Ph-Open Transition ATS/LC-NEMA 3R

…Open-Transition 100A 3Ph NEMA 3R ATS/Load Center

Three-phase RXT-series automatic transfer switch units are offered in these voltages: 120/208, 120/240, 277/480. These switches are engineered for compatibility with Kohler's residential & light-commercial RCL-series standby machines. The Kohler ATS should not be purchased for use with the product of another manufacturer unless compatibility can be guaranteed. The appropriate switch for your application will normally depend on the amp-rating of a structure's circuit-breaker box. Most of the time, you will want the breaker box and automatic transfer switch to align (for instance, a 100-amp circuit-breaker box will work with a 100-amp automatic transfer switch). All Kohler 3-phase switches sold by T-Rex are open-transition (rather than service-entrance rated) models. This requires that your electrician install a separate external (not part of the transfer switch itself) disconnect mechanism to ensure that primary and backup electricity sources do not intermingle. For a service-entrance rated 3-phase switch, see our Asco products (these high quality industrial-based units are compatible with all generator brands). If possible, consult with your electrician regarding the best switch for an individual application. This three-phase 100-amp outdoor-mount automatic switch & load center can be used with these generator models: 38RCL liquid-cooled 3Ph, 48RCL liquid-cooled 3Ph. NEMA 1 enclosures steel; NEMA 3R enclosure aluminum. Five-year warranty.

    The T-REX Free Shipping Pledge:
    The manufacturers we work with are large concerns that ship multiple items each day. This enables them to attain the best shipping rates available. T-REX passes these savings on to our customers by providing free shipping to any commercial or residential address in the continental United States. This is the T-REX pledge. We will adhere to it even when a freight carrier adds one-time or unanticipated shipping fees. Try obtaining these terms from another Internet-based generator seller. You will not find a more customer-friendly policy than ours.

    Residential Delivery:
    You need to inform us if your delivery will be going to a residential address. Freight companies need to know this because many residential areas can't be serviced by large semi trucks. The generator will instead be loaded onto a smaller truck tailored to home deliveries. A home which serves as a place of business (regardless of the presence of company name/signage), if located in a residential area, is still considered a residential address for shipping purposes. Please select the residential delivery option if applicable. T-REX agrees to pay all additional residential delivery costs, but to do so, we must be properly informed before shipping arrangements are made.

    To select your choice of residential or commercial delivery, please see the purchase options in the Add To Cart area.
