Timer switch contactor connection:

This circuit diagram shows the timer switch contactor connection. Timer contactor wiring. 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. This circuit is very simple and easy to make. If you want to know more about this circuit please check our youtube video below the post. For more learning please stay with us.

Components used to make the Timer wiring:

01. DP MCB

Fig 2: DP MCB

Double pole MCB can control two wires. This circuit breaker is generally used in single-phase electric lines. Double pole MCB circuit breaker input has two wires supply two wires and an output. In a single-phase line, A double-pole MCB circuit breaker is used to give good production. This circuit breaker is provided through phase and neutral circuit breaker, it is very safe. This circuit breaker is preferred for home appliances. A DP MCB usually trips for 2 reasons 1. Overload 2. Short circuit.

02. RCCB

Fig 3: RCCB

The RCCB (Residual Current Circuit Breaker) or RCCB is an electrical protective device.Residual Current Circuit Breaker is specially designed to protect the electrical circuit against earth fault and human from electrical shock.In this, under normal condition the load is always connected in between the phase terminal to neutral terminal, hence the flow of phase current is equal to neutral current.Earth fault or fault in a power system can cause excess heating, more power consumption, burning or fire, etc. So, protection against earth leakage is very important.

03. Contactor

Fig 4: Contactor

A magnetic contactor is an electrical device used for load control, automation, and protection. It is much like a magnetic reel. However, relays are generally used for low power and voltage, on the other hand, when we think of high power, these heavy-duty contractors only come to mind. It basically works by switching the load on and off. It has 3 terminals whose inputs are denoted as L1, L2, L3, and outputs as T1, T2, and T3. The circuit of the load is made in automation mode or protection using auxiliary contacts. It has two types of terminals. 1) Normally Open (NO). 2) Normally Closed (NC)

04. Timer

Fig 5: Timer

Timer is a specialized type of clock used for measuring specific time intervals.An electromechanical cam timer uses a small synchronous AC motor turning a cam against a comb of switch contacts. This type of timer often has a friction clutch between the gear train and the cam, the cam can be turned to reset the time.A simple example of the first type is an hourglass. Working method timers have two main groups: hardware and software timers.Most timers give an indication that the time interval that had been set has expired.

05. Transformer

Fig 6: Transformer

Electricity can be transferred from one AC circuit to another using a transformer. The electromagnetic induction concept is used by a transformer to either step-up or step-down the AC voltage. Transformers are widely used to reduce the power in the circuits of low-voltage devices like doorbells. This diagram shows Transformer 2 type step-up & step-down. Transformer has 240V primary windings and center-tapped secondary winding. The Electric transformer has flying-colored insulated connecting leads (Approx 100mm long). The Transformer act as a step-down transformer reducing AC - 240V to AC - 6v, 9v, and 12V.
