RotaryConnect™ Manual Transfer Switch
Focused, Flexible Power Switching Solutions
RotaryConnect™ by ESL Power Systems is a rugged, easy-to-deploy UL/cUL 1008 Manual Transfer Switch, with rotary switch and single pole cam technology designed to streamline power transitions for a variety of backup and maintenance applications.
Available in multiple configurations from 100A to 1200A up to 600VAC, RotaryConnect includes advanced features such as a phase rotation monitor, 3-point terminal block for remote start/stop signal, and an auxiliary contact for added flexibility and control.
Whether you’re toggling between generator sources, performing routine load bank testing, or managing emergency power needs, RotaryConnect offers safe, cost-effective switching.
Explore how RotaryConnect fits your application:
1. Generator-to-Generator Switching
Perfect for: Permanent Generator to Portable Generator connection (Gen-to-Gen transfer)
When you need a cost-effective and safe way to transfer power between two generator sources outside of high fault current utility environments, RotaryConnect delivers. This configuration enables seamless toggling between a permanent generator and a portable backup – ideal for facilities with planned maintenance, limited utility access, or mobile redundancy needs.
- No concern over utility fault current
- Simplified installation
- Quick camlock connectivity for easy setup
- Cost-effective
2. Load Bank Selector Switch
Perfect for: Permanent Generator > ATS > Load Bank applications
*Female cam configuration
RotaryConnect can be utilized as a load selector switch, helping service providers and generator dealers streamline load bank testing, especially in facilities with ongoing maintenance contracts or compliance requirements.
- Simplifies periodic load testing
- Ideal for retrofits and non-Article 700 systems
- Quick camlock connectivity for easy setup
- Cost-effective
3. Manual Transfer Switch (MTS)
RotaryConnect functions as a basic manual transfer switch, designed to assist in situations where a switch is all that’s necessary to perform the emergency power transfer.
- Ideal for applications dealing with Fire Pumps
- Ideal for existing facilities where breaker-based solutions would require extra coordination studies
- Quick camlock connectivity for easy setup
- Cost-effective
In situations where circuit and fault protection are needed, ESL recommends the StormSwitch®, which is specifically engineered to safely manage utility-level fault currents.

Frequently Asked Questions
Unlike traditional transfer switches designed for utility-to-generator transfer with fault current protection, RotaryConnect is ideal for non-utility environments. It’s a flexible, cost-effective alternative to traditional transfer switches, offering quick camlock connectivity, simplified installation, and features like auxiliary contacts and phase monitoring.
RotaryConnect is ideal for facilities with planned generator maintenance, limited or no utility access, or where mobile redundancy is required. It also benefits service providers and generator dealers performing routine load bank testing or working with aging infrastructure. Common use cases include hospitals, data centers, manufacturing plants, and critical infrastructure sites.
RotaryConnect lets facility managers switch between permanent and portable generators easily. It’s perfect for planned maintenance or remote sites without utility service—offering power continuity without the complexity of traditional transfer switches.
RotaryConnect simplifies load bank testing and retrofits for aging systems. With quick-connect camlocks and a female configuration, it helps generator dealers save time, stay compliant, and reduce installation challenges during service calls.
Yes, but only in limited scenarios. RotaryConnect can function as a manual transfer switch for emergency power, particularly where utility fault current isn’t a concern such as fire pump applications or existing facilities avoiding costly coordination studies. For higher fault current protection, ESL strongly recommends the StormSwitch®, which is purpose-built for utility-to-generator transfers.
