Abstract: The invention relates to a modular disconnect switch (10) for use in an electrical enclosure cabinet (26) having a plurality of different operating mechanisms that can be assembled with the switch. These include, but are not limited to: a dial-type ratcheting rotary switch with a door-sensitive actuating mechanism (40), a dual rotary switch (30) that meets certain standards and provides a butterfly handle inside the cabinet, a lock accessory (60) for enabling the lockout of the switch in the off position, a motion translator device (50) for interfacing to a side-mounted cabinet door handle, a network connectivity module (70), and a module for adding at least one switch pole to the basic disconnect switch (10).

Abstract: A rotary switch assembly for mounting on a disconnect switch (10) in an electrical enclosure (26) includes a base (50) and a rotor (60) which is rotatably coupled to the base (50). The rotor (60) is first axially depressed and then rotated to switch the disconnect switch (10) to the “on” position. The base (50) has a stop member (53) for latching the rotor (60) in an “off” position before the rotor (60) is axially depressed. A lockout tab (43) is attached to the rotor (60) for locking the switch in the “off” position. A rotary handle (30, 90) is provided for mounting on the rotor (60), for operation in either rotational direction. The rotary handle (30) has two wings with formed grips (34, 35) for thumb and fingertips to securely grip and turn the handle (30) with the required torque for actuating and de-actuating the disconnect switch.

Abstract: A fuse status indicator assembly (40, 41, 42) for insertion in an opening (31) in a side wall of the fuse cartridge (20a, 20b, 20c) including a fuse (35) has a snap-in removable carrier (41) in the event that the bulb (42) has burned out and must be replaced. Labels (22) are attached to the fuse cartridges (20a, 20b, 20c) to identify the circuits and ratings of the fuses (35).

Abstract: A swich comprises pack-aligned switching units 9, each provided with fixed 30 and movable contacts 36 operable by a cam shaft 11 rotatably passing through the switching units 9 to close and break electric circuits to which said contacts lead off. The shaft is supported, at one free end thereof, by a terminal closure element 10 fixed to the switching units 9 and is connected, at its opposed end, to a trip mechanism 12 located in a trip unit 8 fastened to said switching units. The switching units, trip unit and terminal closure element constitute each a modular unit engageable with other modular units by restrained fixing and disengageable therefrom without bringing about the disassembly and division of said unit into its component parts. The cam shaft is comprised of several hub-shaped elements 40 consecutively engaged in a rotational direction and associated each with a switching unit.
