EMSCO got in a load of high amperage Square D Bus plugs. These bus plugs are a mixture of fusible and breaker plugs available in a wide variety of amperages, such as models PTQ46160GH and PTPA361000N. In addition to these bus plugs, we have a huge stock of Square D busway all the way up to 4000 amp.

EMSCO recently got in seven (7) GE Spectra 4000 amp 480/277 volt main breaker panels with Spectra breaker distribution. The main breakers are GE Power Break II SSD40G440 with Entelliguard Trip TU Trip Unit. All have multiple SKLL frame 1200 amp branch feeders breakers. Each feeder breaker fed a GE Spectra 1200 amp 480/277 Volt MLO panel that are also now part of EMSCO’s stock.

We’ve been hearing from some of our customers who have tried to place orders for new stock from Square D that they’ve encountered long lead times (several weeks to months) and have instead turned to EMSCO to quickly get the industrial electrical equipment they need. It turns out the long lead times from Square D are a result of being a supplier for a massive construction project from Google to build up to 11 new data centers, of which Square D has won the contract to provide the electrical infrastructure.

Aside from EMSCO’s massive inventory of industrial electrical equipment, we have the best lead time in the industry. If you are down and need to get up and running ASAP, we’re the place to call! With a major food producer down, EMSCO was able to ship a Square D NW40 main breaker lineup with multiple distribution sections and breakers same day to get them up and running again right away. Not only that, but we also completed a Square D Model-6 Motor Control Center lineup in 2 days after a company was down and couldn’t wait the long lead time for new. That MCC included starter, feeder and VFD buckets.

Whether it’s a single section of busway, a single breaker or bus plug, or a complete lineup, EMSCO has you covered to get you back up and running ASAP! We’re standing by 24 hours for all your after hours emergencies. Simply give us a call anytime (1-800-328-1842) and we’ll be ready to jump into action.

It’s been a little while since we’ve written an overview post highlighting one of our main product categories. We’ve covered a few different topics in the past — such as our introduction to bus plugs post — to highlight and provide some general information about the products and lines that EMSCO carries. In this latest post, we’ll be covering the basics of Motor Control Centers.

BASICS OF MOTOR CONTROL CENTERS (MCC)

Motor control centers, at their most basic, contain a series of buckets housed in a larger structure. In industrial and manufacturing settings where electric motors are used, there needs to be a system to control such motors. That is where the motor control center comes in.

HOW THEY WORK

Feeder buckets are what power and control the electric motors. Generally, a single bucket controls a single motor. With most industrial processes using many electric motors, multiple buckets will be required to control the system. The structure, simply, is the vertical housing to hold and control all of the feeder buckets in one convenient central location.

The buckets inside the structure come in multiple sizes and configurations. For example, the buckets may either be fused or circuit breakers. The buckets themselves are also fully removable from the structure allowing flexibility for the electric system to adapt to changes in the industrial systems. For example, if additional motors are added or removed, additional buckets can simply be added or removed from the structure or swapped out for the correct components to be installed.

NEED PARTS?

Looking to replace, upgrade, or install a new MCC system? Look no further. We have hundreds of vertical sections of motor control centers ranging from 400 amperes all the way to 3000 amperes, with main or main lug compartments. We have extensive stock in all the major brands including Square D, GE, Allen Bradley and much more. With thousands of buckets in stock in both fusible and breaker styles, from sizes 0-6, single and twin feeder buckets, EMSCO is sure to have what you need!
