Over the years ee have been developing a quick solution to retrofit Schneider Merlin Gerin ACBs from Masterpact M to Masterpact NW through the entire range of sizes from 800A to 6300A. 

The procedure requires a small shutdown and then at the end of the shut down the old Merlin Gerin Masterpact M ACB is removed and the new Merlin Gerin Masterpact NW ACB is installed, along with the new chassis, intergrated control (if applicable), and readily available spares.

Michael Smith Switchgear retrofit any ACB and can replace any manufactures ACBs with new ACBs.  The works will be arranged at a time to suit the business needs and with minimal disruption.

If you have any queries please do not hesitate to contact us.

Michael Smith Switchgear can also replace any existing ACBs and retrofit new ACBs into the same space.

Please do not hesitate to contact us for more information.

Power Factor Correction (PFC) will help to reduce the reactive power consumed within a business and therefore save money.  A Power Quality Survey can be arranged to calculate the requirement of Power Factor Correction (PFC) equipment within an existing system.

If you have any queries please contact us.

These can incorporate DOL Starters, Star-Delta Starters and Variable Speed Drives (VSD) to suit your requirements.

The basic functions of LV Switchgear

The role of lv switchgear is:
1. Electrical protection
2. Safe isolation from live parts
3. Local or remote switching

National and international standards define the manner in which electric circuits of LV installations must be realized, and the capabilities and limitations of the various switching devices which are collectively referred to as lv switchgear.

The main functions of lv switchgear are:

• Electrical protection
• Electrical isolation of sections of an installation
• Local or remote switching

Electrical protection at low voltage is (apart from fuses) normally incorporated in circuit-breakers, in the form of thermal-magnetic devices and/or residual-current operated tripping devices (less-commonly, residual voltage- operated devices – acceptable to, but not recommended by IEC).

In addition to those functions above, other functions, namely:

• Over-voltage protection
• Under-voltage protection

are provided by specific devices (lightning and various other types of voltage-surge arrester, relays associated with contactors, remotely controlled circuit-breakers, and with combined circuit-breaker/isolators… etc)
