Our professional Project Management team provides you a single point of contact so that you know exactly the status of your solution throughout the order cycle. Benefits Reduces release of toxic materials Eliminates need for reinforced switchgear Elimnates special requirements for buildings or plenums Minimizes equipment damage.
We want you to have a seamless experience. Working with Powell makes your life easier.
This creates a three-phase short circuit fault confined to the main Arc resistance switchgear. The current sensor module and the control logic process incoming current and optical signals and send a signal to the output triggering circuit.
Type 2 construction provides protection from the front, rear and sides. At Powell, project management is a key element in our solution. We can say without hesitation that Powell Delivers.
The Powell design is available with any of the construction types. There is a reason why we have loyal customers.
Type 2B construction provides protection from the front, rear, sides and between adjacent cubicles. A high-speed closing, or shorting, switch is designed to close on the main bus of the switchgear.
A dedicated, properly sized set of current transformers is located at the incoming power source s. In the event of a confirmed arcing fault inside a Masterclad switchgear or Motorpact equipment lineup containing an Arc Terminator AT system, the AT system provides a low impedance parallel path to effectively transfer the fault current from the arc to the 3-phase main bus assembly of the switchgear.
Upstream protective device must clear fault within allowed time per applicable standard. It is designed to direct the flow of the gases and debris resulting from an arc fault away from adjacent equipment and operating personnel. Type 1 construction provides arc resistant protection from the front of the equipment only.
Studies show that the most likely occurrence of an arc fault is when the circuit breaker element is changing position or when closing the circuit breaker after a down time event. The controller box is the central processing device that responds to the signals given by the current sensors and the optical sensors.This switchgear and all its components meet the IEEE C arc-resistant test guideline for Type 2B enclosures as well as all other applicable ANSI, UL, and CSA standards for metalclad switchgear.
IntelliSafe™ M&I Electric’s IntelliSafe™ Arc Resistant MV Switchgear is designed with the vision that “safety is not an option”.
Our improved Arc Resistant design provides industry leading, patent pending safety features including a simple but rugged door design, door to breaker position interlocks, automated electrical racking, and intelligence built in to help prevent failures and. VacClad-W arc-resistant switchgear is a metal-clad, medium-voltage switchgear designed to safely contain and redirect the thermal energy and blast from an arc fault should they occur, regardless of the originating location of the arc.
Arc resistance provided from the front, sides and rear; (LV) switchgear and arc resistant MV motor control. Eaton also offers a unique “arc preventative” LV motor control center (FlashGard) that protects the operator by reducing the likelihood that an arc would occur.
The internal arc resistance of switchgear denotes its ability to withstand arc faults. And, should an arc fault occur, to contain it within a single compartment in the. PowlVac-AR ® switchgear is available in three construction types depending upon the exact needs of the end-user.
Type 1 construction provides arc resistant protection from the front of the equipment only. Type 2 construction provides protection from the front, rear and sides.Download
