PowerCommand® 40-11 Control
The heart of this transfer switch is the PowerCommand 40-11 microprocessor-based control system. It features an intuitive LCD digital display and tactile soft-switch buttons that make operation and navigation simple and straightforward. All settings and adjustments are software-enabled, ensuring precise configuration and easy setup for your specific application.
What Makes It Reliable
This transfer switch is built for dependability when you need it most. It monitors both your primary power source and generator, automatically starting your generator and transferring your electrical load during power outages. The system is approved for use in emergency, legally required, and optional standby circuits.
Advanced Transfer Mechanism: Unlike traditional transfer switches with complicated gears and linkages, the OTEC uses a bi-directional linear motor actuator. This innovative design provides smooth, friction-free operation with consistent force and reliable straight-line action.
Safety First: Built-in mechanical and electrical interlocking prevents dangerous source-to-source connections, ensuring your primary power and generator can never be connected simultaneously through power or control wiring.
Manual Override Capability: Should you need to operate the switch manually under de-energized conditions, convenient manual operating handles with shielded termination and over-center contact mechanisms make it possible.
Easy Maintenance: Serviceability was a priority in this design. Plug-style connections, door-mounted controls, generous access space, and clearly marked terminals make installation and maintenance straightforward for technicians.
Ideal Applications
This transfer switch is perfect for commercial buildings, light industrial facilities, healthcare clinics, retail locations, office buildings, and any application requiring dependable backup power protection.
