The full meaning of MCB is Miniature Circuit Breaker. MCB is an electromagnetic switch or device. If for any reason a short circuit occurs in the supply line or load line (line to line or line to neutral) or in case of overload, the MCB automatically trips and disconnects the main line circuit or household power Connection. TP MCB In Three Pole MCB, Switching & Protection is affected in only Three-Phases and the Neutral is not part of the MCB. 3 pole MCB signifies the Connection of Three Wires for a Three-Phase system R-Y-B Phase. Three-Phase Supply Only Without Neutral.

A Mechanical Switch That can be rotated Left, right, or center to open or close the electrical contacts is known as a Selector switch. The Main Function of This Selector Switch is to Control Devices and also to Switch Between a Minimum of 2 or Above Electrical Circuits. The Perfect Used for Selector Switch is When Used for Controlling an Output of a Device. We know that a Selector switch is Used to control the electrical current flow in a Circuit it can also be used to both Initiate and inhibit the Current Flow.

Photocells and Motion Sensors are Electronic Devices you can use to Manage Indoor or Outdoor Lighting. The Main Difference Between Photocells and Motion Sensors is that the Former Detects change in light Levels, and The Latter React to Physical Movement. Movement in the Detection area Changes the Reflected Signals and Activates the Sensor. They also save Energy by Turning Themselves off when Light is Unnecessary. Many Motion Sensors use a Combination of Detection Methods to Provide enhanced Coverage and eliminate false positives. The adjustable timers built into some Sensors let you Control how long the Attached Lights Remain Active after it Detects Motion.
