This series has a completely new contactor structure.
A new mechanism has been developed to eliminate magnetic force generated at the contacting surface. This mechanism greatly improves the short-circuit current characteristics.
Excellent contactor structure
A new mechanism has been developed to increase the mechanical strength of the bus against short-circuit current. The layout has been improved and the insulation bus that enables easy insulation between buses has been achieved. Thus, the short-circuit current characteristics have been improved greatly.
