Product Overview
This Cummins 225A automatic transfer switch delivers reliable emergency standby power switching for commercial and light industrial facilities. Designed as a non-service rated unit with NEMA1 enclosure, it operates at 277/480V 3-phase and is suitable for emergency, legally required, and optional standby circuits.
The OTEC series provides essential monitoring and control functions including primary source monitoring, generator set starting, and seamless load transfer during power outages. At its core is the advanced PowerCommand® 40-11 microprocessor control system, offering intuitive operation through an LCD digital display with easy-to-use soft-touch switches.
Key Features
PowerCommand® 40-11 Control System The fully-featured microprocessor-based controller includes an LCD digital display and tactile soft-switches that make operation and menu navigation straightforward. All features, settings, and adjustments are software-enabled for precise configuration and ease of setup.
Simplified Service and Maintenance Service technicians benefit from plug-style connections, door-mounted controls, generous interior access space, and clearly labeled terminals that streamline installation and maintenance tasks.
Advanced Transfer Mechanism The bi-directional linear motor actuator delivers smooth, reliable switching action with virtually no friction. This straight-line transfer design eliminates complex gears and linkages for enhanced durability and performance.
Manual Operation Capability Built-in manual operating handles and shielded termination allow for safe manual switching under de-energized conditions, providing flexibility during maintenance or emergency situations.
Safety Interlocking Both mechanical and electrical interlocking systems prevent dangerous source-to-source connections through power or control wiring, ensuring safe operation at all times.
