The PowerCommand® B-Series is revolutionary bypass-isolation transfer switch solution for completely integrated and reliable power systems in mission critical applications.

Innovative High Endurance Mechanism and Blow-on Technology Design

The B-Series transfer switch High Endurance Mechanism (HEM) utilizes electromagnetic force to ensure contacts remain closed during high current faults. When a fault occurs, electromagnetic fields develop around moving and stationary contact arms. The HEM utilizes the resulting electromagnetic forces to firmly hold the contacts together; the higher the fault current the greater the force. The B-Series uses the same HEM technology for both the automatic transfer switch and the manual bypass transfer switch mechanisms.

Features:

• Heavy-duty opening springs enable fast opening times, extinguishing arc faster
• Durable automotive grade microswitches for higher reliability
• Dependable modular architecture utilizing stacked high-performance switching cassettes with arc suppression technology designed for maximizing contact life

PowerCommand® 80 Transfer Switch Control

The revolutionary PowerCommand 80 Transfer Switch Control delivers unrivaled adaptability, connectivity and intelligence. Designed by Cummins Power Generation experts, the PowerCommand 80 is a single integrated control - no extra modules are need. All functionalities can easily be implemented as needed without add-on hardware. In addition, the control features a highly customizable customer inputs/outputs which can be tailored to suit a wide range of application requirements.

Easy-to-navigate HMI

The control human machine interface (HMI) includes a LED backlit LCD display with tactile-feel soft-switches for easy operation and screen navigation. All data on the control can be viewed by scrolling through screens with the navigation keys. Forward and backward navigation functionality is also provided. The control displays the current active fault, fault occurrences and time-ordered history of the 256 previous faults with respect to Real Time Clock Stamp and Engine Running Time.
