The WIMA MPX21W2330FD00MSSD is a motor system safety disconnect switch designed to prevent accidents due to electric shock. The switch has a double-throw design that isolates the motor power circuit when the handle is disengaged, interrupting the power to the motor. The switch also features a unique locking system that prevents unauthorized operation. The contact spring is made from silver-plated/gold-plated Beryllium copper for excellent electrical and mechanical properties, and the contacts and terminals are formed from impact-resistant, flame-retardant polycarbonate material. The enclosure is made from corrosion-resistant stainless steel, and the operating handle is housed inside a robust, knurled aluminum guard for added safety. The switch is rated for AC3 duty and is UL certified for use in industrial applications.
