Product Overview
This Cummins OTEC Series Spec B automatic transfer switch delivers reliable emergency standby power switching for commercial and light industrial facilities. Rated at 600 amps, 277/480V 3-phase, this non-service entrance unit features a NEMA1 enclosure and comes equipped with the advanced PowerCommand® 40 control system.
The OTEC Series is engineered to handle essential functions including primary source and generator monitoring, automatic generator starting, and seamless load transfer during power outages. It's approved for use in emergency, legally required, and optional standby circuits.
Control System
The integrated PowerCommand® 40-01 control represents the latest in transfer switch technology. This microprocessor-based system features an intuitive LCD digital display with tactile soft-switches that make operation and navigation straightforward. All settings, features, and adjustments are software-enabled, ensuring precise configuration and simplified setup.
Key Features
The switch incorporates an advanced bi-directional linear motor actuator that provides smooth, friction-free operation with constant force and straight-line action—no complicated gears or linkages to maintain. For safety and flexibility, manual operation is available through dedicated handles, allowing the switch to be operated manually when de-energized.
Service accessibility is built into the design with plug connections, door-mounted controls, generous access space, and clearly marked terminals. Dual mechanical and electrical interlocking safeguards prevent dangerous source-to-source connections through either power or control wiring. The over-center contact mechanism and shielded termination provide additional operational reliability.
