Key Features
PowerCommand® 40-01 Control System
The heart of this transfer switch is its fully-featured microprocessor control with LCD screen. All settings, features, and adjustments are software-enabled, making setup accurate and hassle-free while providing comprehensive control for diverse applications.
Simplified Maintenance & Access
Service technicians will appreciate the thoughtful design: plug-style connections, door-mounted controls, generous access space, and clearly marked terminals make installation and maintenance straightforward.
Advanced Transfer Mechanism
A bi-directional linear motor actuator powers the switching mechanism, delivering smooth, friction-free operation with constant force and straight-line action. No complex gears or linkages mean fewer parts to fail and more reliable performance.
Manual Operation Capability
When needed, manual operating handles allow you to operate the switch under de-energized conditions. Shielded termination and over-center contact mechanisms ensure safe, effective manual control.
Safety Interlocking
Both mechanical and electrical interlocking systems prevent accidental source-to-source connection, protecting your equipment and facility from dangerous backfeeding through power or control wiring.
