A coupler between an activator mounted on an enclosure and an electronic protection device located within the enclosure facilitates alignment between the coupler and the electronic protection device during installation and requires no tool for installation. The coupler is positioned over an opening in the electronic protection device and oriented such that a first coupling portion is configured to engage a complementary coupling portion on the electronic protection device. The coupler may be manually mounted, engaging the complementary coupling portions on the door handle coupler and the electronic protection device without requiring a tool for installation. The coupler includes an upper sleeve configured to receive an axle, also connected to the activator, that rotates independently of a lower sleeve which is mounted to the electronic protection device, facilitating orientation of the activator on the outside of the enclosure. The coupler also provides for local lock-out of the electronic protection device.

A disc member is for a Thomson coil actuator of an electrical switching apparatus. The Thomson coil actuator has at least one generally planar coil. The disc member includes at least one annular-shaped conductive member structured to be driven by the coil, and a structural support member directly coupled to the conductive member.

A high current switching device includes an electrical switch assembly and an input shaft operatively connected to the electrical switch assembly. An actuator assembly is attached to the input shaft and is configured to move the input shaft to operate the electrical switch assembly. The actuator assembly includes a mechanical advantage device operatively attached to the input shaft. An actuator is coupled to the mechanical advantage device such that movement of the actuator causes movement of the input shaft to operate the electrical switch assembly. The mechanical advantage device is configured to decrease an amount of force required to move the input shaft by the actuator.

A coupling system for securing an elongated rod to a connector that links the elongated rod to a device, and methods therefor, are disclosed herein. The coupling system includes a swivel member pinned in a receptacle of the connector, and a fastener secured to the swivel member. The elongated rod is secured to the fastener. The elongated rod may be a conductor rod and the device may be an interrupter for a circuit breaker.

An electrical disconnect switch including an over-rotation protective feature to protect the load switch from damage is disclosed. The electrical disconnect switch may include an enclosure, a load switch, and a handle assembly coupled to the load switch. The disconnect switch may include a detent between the handle assembly and the load switch so that during excessive rotation or torqueing the handle assembly is permitted to decouple or break-away from the load switch to prevent excessive stress from being transferred to the load switch and thus prevent any damage to the load switch.
