What It Does

The OTEC400 automatically monitors your primary power source and backup generator, initiating generator startup when needed and smoothly transferring your electrical load during power outages. It's approved for use in emergency, legally required, and optional standby power systems.

Key Benefits

Intelligent Control System - The PowerCommand 40-11 control features a clear LCD screen and user-friendly touch buttons, making it simple to monitor system status and adjust settings. All configurations are software-based for precise, reliable operation.

Built for Reliability - The innovative bi-directional linear motor actuator provides smooth, consistent switching action without complex mechanical parts that can wear over time. This design means fewer maintenance issues and longer service life.

Easy Installation & Maintenance - Designed with technicians in mind, the OTEC400 features plug-style connections, control panel mounted on the door for easy access, clearly marked terminals, and spacious interior layout that simplifies both installation and future service calls.

Safe Manual Override - In the event you need to manually operate the switch (during maintenance or testing), protected handles and robust mechanisms allow safe manual transfer when the unit is de-energized.

Dual Safety Interlocks - Both mechanical and electrical interlocking systems prevent the utility and generator from ever connecting simultaneously, protecting your equipment and ensuring electrical code compliance.
