Cummins RA 100 Amp NSE 240V 1-Phase Automatic Transfer Switch

Model A064G345 (RA112N3) | 100 Amp | 120/240V Single-Phase, 2-Pole | Non-Service Entrance (NSE) | NEMA 3R Aluminum Enclosure | UL 1008 Listed | Compatible with Cummins RS Series Generators

Product Overview

The Cummins RA 100 Amp Automatic Transfer Switch (MPN A064G345) is a genuine OEM accessory designed to provide reliable power transfer between utility and generator sources. Engineered for 120/240V single-phase applications, this Non-Service Entrance (NSE) ATS ensures continuous and automatic power availability for residential and light-commercial installations. Built with precision and durability, it guarantees smooth operation, quick response, and long-term reliability under all load conditions.

This 2-pole switch uses a break-before-make design that fully isolates generator power from utility power, backed by both mechanical and electrical interlocks that prevent simultaneous connection to emergency and normal power sources. Long-life, high-pressure silver-alloy contacts resist burning and pitting, while mechanically held contacts in both normal and emergency positions keep the unit quiet during operation.

Key Features

100 Amp, 120/240V Single-Phase Rating: Built for whole-house or light-commercial electrical systems requiring dependable standby power.

Automatic Power Transfer: Monitors utility power 24/7 and automatically transfers loads between utility and generator sources during outages, with no homeowner action required.

Cummins Quiet Connect Compatibility: Designed for integration with Cummins RS Series Quiet Connect standby generators.

Non-Service Entrance (NSE) Configuration: Suitable for protected installations where service entrance switching is handled by a separate device.

Break-Before-Make Switching: Isolates generator power from utility power, with mechanical and electrical interlocks preventing simultaneous connection to both sources.

Durable Silver-Alloy Contacts: High-pressure silver-alloy contacts resist burning and pitting for extended mechanical and electrical life.

Corrosion-Resistant Enclosure: NEMA 3R aluminum housing rated for dependable indoor or sheltered outdoor use.

Installation & Application

The Cummins RA 100 Amp NSE Automatic Transfer Switch provides dependable power switching for standby systems. When a utility outage occurs, it automatically transfers the electrical load to generator power, and switches back once the grid is restored. Compact, efficient, and built for reliability, it is ideal for residential properties, small businesses, and light-commercial sites requiring automatic standby power availability.

Installation: Field-installable by a certified Cummins technician or licensed electrician; suitable for both indoor and sheltered outdoor mounting due to the NEMA 3R aluminum enclosure.

Customer Success Stories

Troy P

EG4 off-grid base kit, Happy with my purchase.

This is the first stage of my three planned purches. I got the eg4 inverter 6000 XP base kit with six 400 watt panels and the two server rack batteries. Did a little online research and followed the instructions and it got set up without any issues. Right now I'm just running it in my garage on a single outlet and have been running dual 750 watt water distillers with it. Once I get the second inverter and a bunch more panels and batteries, I plan on attaching it to my subpanel in my house that has my lights and outlets and appliances on it. Then I'll get a soft start for my AC and blower and run it on my main panel.

Jacob B

Easy Process, Genuine Support

Trying to pick the correct solar system for your needs can be very technical and frustrating. I wanted to thank Yvhan and the Portlandia Electric supply team for their patience and helpful attitudes through multiple calls. I feel like we were able to narrow it down to what worked for me and my family. My system works great and I couldn't be happier to have picked Portlandia Electric Supply.

Patrick B

Off Grid Solar Purchase

I wanted to get an offgrid solar system for years but didn’t know where to start. I found Portlandia Electric Supply on Facebook and decided to submit a quote. Within 24 hours I had a custom proposal that was almost half the price of the companies I had previously got quotes from. My wife and I decided to order online and the kit came in a timely manner and it was an easy install. Great company to work with!

James Martin

Highly Recommend

I would like to take the time to express the outstanding service that I was provided with by Portlandia Electric Supply. They provided me with all the answers to my questions, and after reviewing our quote over the phone I felt comfortable proceeding to order my kit. It’s exactly what I needed and they were there to help us over the phone when we had questions installing it. I highly recommend others in need to choose Portlandia Electric Supply.

Solar Kit for Mobile Work Van

As a professional videographer, I needed reliable power on the go.Portlandia Electric Supply Delta Pro and roof-mounted panels were the perfect solution. Setup was easy, and the kit included everything needed. The Delta Pro powers my cameras, lights, laptop, and a small fridge with impressive battery capacity.

Keith S

Best Tech Support

You folks have been wonderful guiding me through the ins and outs of going solar. Plus your tech guys Rod and Nelson are the absolute best. They explained all the different aspects of inverters, batteries and how to keep them in top condition. Too much more to put here… but no other company has the 100% tech support you provide for your customers!

Coll A

Great Experience

My experience with Portlandia Electric Supply has been excellent. Before the sales, they answered all my questions to assure that I got what I needed. After the sales they continued to support me with answers and help. I had a warranty issue with a unit, and it was handled as well as possible. I would recommend them to anyone looking to go solar.
