An RCBO protects electrical equipment against two types of faults; Residual current and over current. Residual current, or earth leakage as it is sometimes referred to, occurs when there is a break in the circuit which can be caused by faulty electrical wiring or if the wire is accidentally cut. When there is a break in the circuit which may be due to faulty electrical wiring or accidental cutting of the wire. To prevent the current from being redirected and causing an electric shock, the RCBO current breaker stops it.

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.

3 Phase Solid State Relay is a fully Integrated Device with a Heat sink and DIN rail Mounting plate in a Space-Saving design. Each unit is Touch-Safe with LED input Indication. This Normally Open, Zero-Crossing device is Capable of Millions of Cycles of Operation. There are three main types of solid-state relay isolation methods used in SSRs, i.e., optical, transformer, and reed Solid-state relays are the semiconductor equivalents of electromechanical relays and therefore can be used to control electrical loads.
