Timer with contactor wiring

Timer with contactor wiring:

This circuit diagram is shown as Time Switch Operation With Contactor Wiring Diagram. 8-pin timer to Main RCBO connection. The control to time is 12 Hours. The contactor works for single-phase motor control. short circuit time to time on-off motor. Plug your device into the outlet on the front or side of the timer.

Components used to make the 8-pin timer wiring:

01. RCCB  

Fig 2: 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.

02. RCBO  

Fig 3: RCBO

RCBO Stands For Residual Current Circuit Breaker With Over-Current. These devices are designed to ensure the safe operation of electrical circuits breaker, triggering disconnection whenever an imbalance is detected. The other type of electrical fault is the overcurrent flow, which may take the form of an overload or short circuit. The residual current circuit breaker (RCBO) insulation should also operate within the corresponding specifications. This thereby provides protection for people, equipment, and property.

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.
