In electrical engineering, a disconnector, disconnect switch or isolator switch is a type of switching device with visible contacts, used to ensure that an electrical circuit is completely de-energized for service or maintenance.
Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.

A contactor is an electrically controlled switch used for switching an electrical power circuit. [1] A contactor is typically controlled by a circuit which has a much lower power level than the switched circuit, such as a 24-volt coil electromagnet controlling a 230-volt motor switch.
The phase coils are traditional wound in a single coil assembly with the 0 to 50% winding section buried below the 50% to 100% windings in a single thermal mass as shown in figures 2 and 3 Figure 4. 3 Coil Assembly. Figure 4 shows an improved 1000 kW 11,000 Volt motor starter autotransformer with Axial cooling fans, Cast resin encapsulated coils,
The yellow P+N+E, 4h (120°) plug is a single phase connector that is in widespread use on the British Isles for 110 V building site and fairground applications. A popular model of this socket type is marketed under the brand name MK Commando [ 12 ] which leads some users to refer to all IEC 60309 sockets by the generic trademark Commando sockets .
Simplified single line diagram of a single-phase transfer switch to select either 'city' (utility) power or local generator power 3-phase Intelligent transfer switch. A transfer switch is an electrical switch that switches a load between two sources. Some transfer switches are manual, in that an operator effects the transfer by throwing a ...
