Designed for Critical Power Applications
This transfer switch is engineered to provide seamless power transitions during outages, making it ideal for emergency, legally required, and optional standby circuits. The OTEC series monitors both your primary power source and backup generator, automatically initiating generator startup and load transfer when needed to keep your facility operational.
PowerCommand® 40-11 Control System
At the heart of this transfer switch is the sophisticated PowerCommand® 40-11 microprocessor-based control. The intuitive LCD digital display and tactile soft-switches make operation and navigation straightforward, while comprehensive software-enabled features allow precise customization for your specific application requirements.
Built for Reliability and Easy Maintenance
Advanced Transfer Mechanism: The bi-directional linear motor actuator delivers smooth, friction-free operation with constant force. Unlike traditional designs with complex gears and linkages, this straight-line transfer action ensures long-term reliability.
Service-Friendly Design: Maintenance is simplified through thoughtful engineering—plug connections minimize wiring complexity, door-mounted controls provide convenient access, and compatible terminal markings make troubleshooting straightforward.
Manual Operation Capability: In de-energized conditions, the shielded termination and over-center contact mechanisms with manual operating handles allow safe manual switching when needed.
Safety Interlocking: Both mechanical and electrical interlocks prevent dangerous source-to-source connections, protecting your electrical system and equipment.
