Eco Changes is the Mitsubishi Electric , Group s environmental statement, and , expresses the Group s stance on environmental management.
Solve Together Mitsubishi's Magnetic Contactors and Magnetic Starters continue to push the boundaries. MS-A Series Double ratings of AC3 grade (Green) and AC4 grade (Red) were adopted allowing the unit to be downsized. 1933 1953 1960 Mitsubishi Electric began making Magnetic Contactors and Magnetic Starters in 1933 with the first EC Series products. Since then consecutive new products and series have been highly appreciated by our customers.
Desire to down-size the switchboard Desire to reduce the types and stock of switchboard parts Do these requirements sound familiar? The new MS-T Series can help you solve these issues.
There is a saying that "every bit helps" and now with the industries smallest* general purpose Magnetic Contactor in its class, customers are able to more easily down-size their boards than ever before. The perennial issues of remembering to order the terminal covers, fitting them correctly or loosing them in the process are challenges of the past. The integrated terminal cover system means they are always there, on the Magnetic Contactor or its Auxiliary contact, ready to be used.
Easy branch circuit wiring with Manual Motor Circuit Breaker and optional connection conductor unit Easy wiring is available for the new MS-T Series by using the Manual Motor Circuit Breaker and optional connection conductor unit, contributing your productivity improvement. The integrated terminal covers offer various benefits not to mention added protection against electric shock through secure finger protection.
