The PowerCommand® X-Series consists of 40-3000A automatic and non-automatic transfer switches with non-service and service entrances. Each product in this suite features the state-of-the-art PowerCommand® 80 control and are designed for markets and applications where the highest performance and system connectivity are required.

Designed for operation and switching of electrical loads between primary and alternate power sources, the X-Series switches can be used in utility-generator set, utility-utility, generator set-generator set, or three source system (dual standby) applications and are suitable for use in emergency, legally required, and optional standby applications.

vision-awards-2021-winner-logo.jpgIn addition, the X-Series offers a full range of industry leading UL1008 Time Duration WCR and Short-time based rating, achieved by Cummins High Endurance Mechanism with patented Blow-on technology, delivering the next level of performance and reliability.

Designed by Cummins experts, the revolutionary PowerCommand® 80 control is a single integrated control All functionalities can easily be implemented as needed without add-on hardware nor extra modules needed.

 

 

Innovative design of the High Endurance Mechanism and Blow-on Technology

The High Endurance Mechanism (HEM) is designed to minimize the contact damage during a fault condition, thus retaining its capacity to carry up to 100% of its rated load.   Electromagnetic forces developed during a fault cause a conventional transfer switch’s contacts to blow open, producing destructive arcing that often results in extensive internal damage to the switch.

Typically, after a conventional switch experiences a fault, its contacts, arc chutes and in some cases, its control will need replacing.  However, the blow-on Technologies utilized by the HEM uses the same electromagnetic energy to hold the contacts closed during a fault, practically eliminating arcing, contact damage, and performance degradation. 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. With the high short-time ratings of this innovative blow-on technology, costly repairs or inconvenient downtime can be minimized after a fault.

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.
