A control system includes an enclosure, a control panel, and a plurality of controls, indicators, or both mounted on the control panel or in the enclosure. At least some of the plurality of controls, indicators, or both are configured to wirelessly communicate with each other inside the enclosure, and at least some controls including wirelessly controlled relays are configured to control devices outside the enclosure. Also, the wirelessly configured controls, indicators, or both are further configured to communicate with a plurality of other controls, indicators, or both in the control system.

Wireless system with multi-device control

A combination circuit breaker/motor starter includes a circuit breaker trip unit having a microprocessor and at least one removably connectable contactor or other functional module. The functional module is encoded with an identifier, such that the microprocessor can determine the type of functional module and appropriate configuration parameters, such as trip times, for the particular application of the functional module. Power is supplied continuously to the trip unit during motor overload or short circuit conditions.

Breaker/starter with auto-configurable trip unit

A motor control compartment provides an air flow chamber at the rear thereof and mounts the solid state switches on heat sinks that are positioned in the air flow. An apertured support plate separates the interior of the compartment from the air flow chamber and allows additional space for supplemental control equipment.

Compact electrical equipment enclosure

A motor controller unit includes an operating program that controllably responds to manual motor start and stop commands for protection of the semiconductor switches connected with each phase of a multi-phase electric motor. Upon receipt of a start command, a determination is made as to whether the measured time lapse between a previous stop command is less than a predetermnined time delay period.
