Hubbell 401M1S Industrial Enclosed Master Switch

Hubbell 401M1S Industrial Enclosed Master Switch is a master-switch assembly that ships with an enclosure box designated Type 4211. The 401M1S model identifies Hubbell’s enclosed master-switch configuration intended for industrial applications where control of power to connected equipment is required from a single switching point. The Type 4211 enclosure houses the switching mechanism, providing a protected housing as part of the assembly used in electrical installations that demand centralized power control. This configuration enables a single interface to interrupt power to downstream equipment, supporting organized wiring and straightforward control within industrial panels and machinery setups. By combining Hubbell’s master-switch functionality with a dedicated enclosure, the 401M1S offers an integrated solution for environments where an enclosed control element is preferred for reliability and tidy power-disconnection points.
