Low Voltage Distribution Equipment
The MNS-MCC, Low Voltage Motor Control Center for ANSI/NEMA/UL is the result of over 30 years of experience with the design, manufacturing and application of low voltage motor control.
To achieve the greatest possible flexibility, the MNS-MCC motor control center offers plug-in, withdrawable and full height unit technology, with up to 4000A horizontal and 1600A vertical bus.
Designed for the highest degree of safety, ease of installation and maintenance, reliability and flexibility, the MNS-MCC provides users with maximum uptime.
Its unique and innovative design raises the bar in arc flash protection for low voltage motor control centers. The MNS-MCC provides industry leading features that afford operators the highest degree of safety and efficiency while performing both normal and maintenance operations.
Up to 100kA at 480V and 65kA at 600V
4000A horizontal bus; 1600A vertical bus available
Arc resistant per ANSI C37.20.7 for 600V 65kA
The MNS® metal enclosed low-voltage power circuit breaker switchgear for ANSI/NEMA/UL offers excellent flexibility due to the modularity of both the electrical and mechanical design. The modularity enables customization of the structural design, interior arrangement and degree of protection.
The switchgear can be outfitted as needed with standardized components to perfectly adapt the MNS-SG to each application. MNS-SG was designed, built and tested to meet all applicable requirements for UL1558, ANSI C37.20.1 and ANSI C37.20.7.
The MNS-SG supports the ABB vision of providing equipment that delivers world class performance under the intense mechanical, electrical and thermal stress of today’s rigorous manufacturing environments.

IEM Switchboards can be custom designed or utilize a standard configuration to meet specific dimensional and electrical requirements. They can include fully integrated component options from leading manufacturers, including automatic transfer switches, TVSS, distribution transformers, and PLC or relay based transfer schemes. Circuit breakers and fusible switches can be group or individually mounted. Indoor and outdoor enclosures are available in a wide range of durable color finishes.
Low Voltage Switchgear - IEM’s unique approach to engineering and manufacturing allows us to assemble products that meet specialized dimensional and electrical requirements.
Our flexible capabilities allow for the selection of industry leading components including control and measuring devices, allowing for a superior, fully customizable control and monitoring electrical assembly. This is just one element of IEM’s superior control solutions to provide protection and operational reliability for any quality power distribution assembly.
Depending on the users’ technical and physical requirements, UL 1066 power circuit breakers can be mounted in a fixed or drawout configuration. Indoor, outdoor non walk-in enclosures are available in an extensive selection of durable color finishes.
Lake Shore Electric Corporation offers a complete line of Manual Transfer Switches which provide dependable, positive, fast-acting manual transfer to an alternate power source. Molded Case Manual Transfer Switches are available in Dual Operator configuration (see Bulletins 07110 & 07120 for automatic versions) allowing two separate operating handles so that the operator may place the switch in a neutral, de-energized position at the operators discretion. Lake Shore Electric Corporation’s Molded Case Transfer Switches are U.L. Listed up to 1200 amps at 600 volts AC or 250 volts DC (U.L. Standard 1008, File No. E32008) and are CSA approved. For Manual Transfer Switches above 1200 amps, please see our medium voltage distribution equipment.
The Lake Shore Electric Corporation Single OR Dual Motor Automatic Transfer Switch provides dependable, positive, programmed delay transfer to an emergency power source in the event of normal power source failure. The switch returns the system to the normal power source in an orderly fashion when normal power is restored. In the event that the emergency source fails, the switch will automatically return to the normal source when it becomes available, bypassing all time delays.
U.L. 1008 Listed (File No. E32008) and CSA approved as suitable for use in emergency systems, these transfer switches are rated for application 225 to 1200 amperes, 600 volts AC or 150 volts DC.
Withstand ratings are very important for Automatic Transfer Switches. These transfer switches are available with standard, high or very high withstand ratings. Withstand ratings are at the terminals of the transfer switch without regard to, or dependence on specific upstream protection. Please see the reverse side of this bulletin to select the switch which best suits your application.
