Timer switch with contactor:
This diagram shows how to make Timer switch with a contractor. In this circuit, we use a DP MCB (Double Pole Miniature Circuit Breaker ), an RCCB (Residual Current Circuit Breaker ), a magnetic contactor, a timer, and a transformer. First, we need to connect the DP MCB with the power source then connect the RCCB and contactor with DP MCB, then connect the transformer.

Components used to make the Timer switch with contactor:
DP MCB In Two Pole MCB, switching & protection is affected in phases and the neutral. A Double Pole or DP Switch is a Switch that Controls two Circuits at the same time. In terms of Residential Switching, this Normally means it Switches the live and Neutral at the same time. In Layperson Terms, Double Pole switches or DP Switches are Exclusively Designed to Control two Different Electrical Circuits at the same time, which allows the Appliances to Isolate in a safe and reliable manner. Fan or light Combinations and Medical Equipment are some of the many applications for DP Electrical Switches.
The Residual Current Circuit breaker RCCB is the Safest device to detect and Trip against Electrical Leakage current, thus Ensuring Protection against Electric shock Caused by indirect contact. Circuit breakers are automatically Operated Electrical Switches that Protect Electrical Circuits from Short-Circuiting or Overloading. It Protects against many major accidents. RCCB Circuit Breaker is an Electrical Wiring device whose function is to disconnect the current in the circuit.
A magnetic contactor is an electromagnetic switching device. It is generally used for controlling three-phase motors. The operation of a magnetic contactor is similar to that of a relay, but a relay is used for low-power or low-voltage connections, and a magnetic contactor is used for high-power or high-voltage connections. As soon as the supply is applied to the magnetic contactor coil, its normally open contacts are closed and normally closed contacts are opened and the associated devices are also operated. This is how a magnetic contactor works.
A timer is a type of time-switching device that controls and controls electrical circuits and electrical and electronic devices through time setting (on/off). The timer is basically 8-pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has two common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.
Using a transformer, electric energy can be moved from one AC circuit to another. A transformer uses the electromagnetic induction principle to either increase or decrease the AC voltage (step-up or step-down). To lower the power in the circuits of low-voltage devices like doorbells, transformers are frequently utilized.
