✅ IN STOCK - Ready to Ship
Latest Spec C Model with Advanced PowerCommand 40-11 Control
When power interruption isn't an option, the Cummins OTEC225 delivers reliable automatic transfer switching for your critical commercial operations. This 225-amp, three-phase transfer switch represents the latest evolution in Cummins' proven OTEC series, now featuring the upgraded PowerCommand 40-11 control system.
Built for Critical Applications
Engineered for emergency, legally required, and optional standby circuits in commercial and light industrial environments, the OTEC225 seamlessly monitors your primary power source and generator, automatically initiating startup and load transfer when needed. Operating at 120/208V three-phase configuration with NEMA1 enclosure protection, this non-service rated unit ensures your operations stay online when grid power fails.
Intelligent Control at Your Fingertips
The PowerCommand 40-11 microprocessor-based control sets a new standard for transfer switch management. Its backlit LCD display and intuitive soft-touch interface make operation straightforward, while software-based settings eliminate guesswork during setup. Every parameter, adjustment, and feature is easily accessible and precisely configurable—no manual calibration required.
Engineered for Reliability and Service
Revolutionary Transfer Mechanism - Unlike conventional designs with complex gearing, the OTEC225 employs a bi-directional linear motor actuator that delivers friction-free, constant-force operation. This straight-line action means fewer wearing parts, quieter operation, and exceptional long-term reliability.
Service-Friendly Design - Your maintenance team will appreciate the thoughtful engineering: plug-style connections eliminate hard-wiring hassles, door-mounted controls provide instant access, and clearly marked terminals speed troubleshooting. Generous interior spacing gives technicians room to work efficiently.
Fail-Safe Manual Override - Should service or testing require manual operation, integrated handles allow full mechanical control under de-energized conditions. The over-center contact mechanism ensures positive switching action even without power.
Complete Protection - Dual mechanical and electrical interlocking systems guarantee sources can never connect simultaneously—protecting your equipment, generator, and facility from dangerous backfeed conditions.
