MSW Disconnect Switches 3
Disconnect Switches
The MSW Disconnect Switches were developed according to IEC 60947-3/UL 508, and enable the manual drive of motors, machines and other equipment. Besides carrying and interrupting electric currents under normal or overload conditions, the design of the MSW Disconnect Switches provides complete physical insulation between the circuit and the power supply when in the OFF position. In this position, it is possible to use three padlocks in order to prevent inadvertent actuation, increasing the safety of operators and maintenance personnel.
The MSW Disconnect Switches are CE and UL certified, and can be used as the supply disconnecting device, meeting the requirements of IEC 60204-1, and as the emergency switching off device.

MSW Disconnect Switches4
The MSW line presents a series of accessories and configurations. WEG offers the full set with a standard configuration. The customer can select the Disconnect Switches and accessories according to the requirements of each application. Below are described the four steps necessary for the proper selection of the MSW Disconnect Switch.
How to Select a MSW Disconnect Switch for your Application
1 - Mounting The MSW Disconnect Switches are mounted on panel doors or bases according to the selected model.
J Mounting on door: in this system, the Disconnect Switch is mounted on panel doors by means of screws. The Disconnect Switch and the handle are always coupled.
J Mounting on base: the Disconnect Switch is mounted on a base, like panel plates, by screws or DIN rail. There is a shaft to couple the Disconnect Switch to the handle. The uncoupling of the Disconnect Switch and of the handle is only possible when the Disconnect Switch is in the OFF position.
The user must define the Disconnect Switch considering the wiring, access, simple mounting or any other criteria which may be deemed necessary.
2 - CurrentThe Disconnect Switch must present a rated current capacity equal to or above the rated current of the circuit/load. The MSW Disconnect Switches stand currents (Ith) up to 160 A for base mounting and up to 100 A for door mounting, according to the selected model. In order to select the Disconnect Switch, some currents are presented in the references according to the load characteristics. Other current values are presented in the table of technical data (page 8).
3 - Handle and ShaftThe handles of the MSW Disconnect Switches, developed with IP65 degree of protection, allow the use of up to three padlocks when in the OFF position, ensuring safety during maintenance. The handles of the MSW line are available in the colors red/yellow and black/gray.For Disconnect Switches with base mounting, besides the handle, it is necessary to use a shaft. The shaft must have a length equal to or longer than the distance between the Disconnect Switch and the handle.
With those characteristics, it is possible to define a standard Disconnect Switch, but WEG offers other accessories that may be required for each application.

Disconnect Switch with 2 auxiliary contacts and 2 terminal covers.
Accessories
Neutral PoleFor applications that require neutral disconnection the MSW line has an additional pole with early make contact, that can be assembled on the side of the Disconnect Switch.
Auxiliary Contacts The MSW line provides auxiliary contacts for mounting on the sides of the Disconnect Switch. On each side of the Disconnect Switch, it is possible to mount an auxiliary contact, or a neutral pole, as shown in the figure on the left.
Terminal CoverAiming at enhancing the safety of machinery and equipment, the MSW line provides terminal covers that reduce the risk of inadvertent contact with the terminals. The terminal covers must cover all the poles with live conductors.
