What Is A Circuit Breaker Timer & Different Types?
Testing the mechanical operating timing of a Circuit Breaker Timer is one way to ensure that it is functioning correctly. The circuit timer is a timer kit for measuring circuit breakers, and it can measure 3/4 poles at once and close, open, and close-open circuits with bounce timing measurement of the circuit breakers up to 220kV ratings. The metres’ benefits lie in their straightforward design, user-friendly communication interface, and straightforward display of measurement results.
The circuit timer has a built-in printer for on-site report printing, a USB connector for data transfer and report generating, and memory for 100 test results. The circuit timer runs on batteries and is compact, sturdy, and easily transportable for use in the field.
What is Circuit Breaker Timer?
As a switching device, the circuit timer provides safety by tripping and interrupting power to the load in the event of a fault. Industries, buildings, commercial complexes, hotels, etc., rely heavily on circuit timers for switching various load types.
Benefits of using a circuit timer
1) it prevents harm from the passage of excessive current,
2) it is more reliable,
3) it can be reset as it functions via a switch,
4) it is susceptible.
Types Of Circuit Breaker Timer
- Low Voltage Circuit Timers
LV, or Low Voltage, Circuit Timers are used for voltages up to 1KV and include the following features:
- Molded Case Circuit Breaker Timer (MCCB)
The Molded Case Circuit Timer (MCCB) is a circuit timer housed in a moulding or casing made of a moulded material, hence the name. It is often employed for fault levels up to 150 KA and current ratings of up to 1600 A. Overload and short-circuit protection is provided by bimetal and solenoid, and microprocessor-based MCCBs are becoming increasingly common as a result of their fast operation and electronic type release.
Miniature Circuit Breaker Timer (MCB)
Miniature circuit breaker (MCB) timers are used for circuit protection in settings with lower current ratings. Like MCCBs, it protects against overload and short circuits using bimetal and solenoid and can be used in circuits with a maximum amperage of 125A. Class 3 MCBs are widely used today because of their fast tripping and low let-through energy loss.
Air Circuit Breaker Timer (ACB)
As the name suggests, an ACB is a timer for circuit breakers in which air is used to quench electrical arcs. The overload and short circuit protection provided by ACB is effective up to 6300A, making it ideal for use in high-current applications. When using ACB, tripping occurs when the inhibitor is released. Since the release indicates the ACB trip in the event of a malfunction, it is sometimes referred to as the “thought of ACB.”
Motor Protection Circuit Breaker Timer (MPCB)
Nothing beats a Motor Protection Circuit Breaker Timer (MPCB) when it comes to protecting motors. Specifically designed for motor applications, MPCBs protect from overload, short circuits, and single phasing when used alone.
Residual Current Circuit Breaker Timer (RCCB)
In the event of an Earth Leak, a Residual Current Circuit Breaker Timer (RCCB) will trip and cut off the power. The current sensitivity necessary for a given application determines where it is used, whether a residence, business, or factory. The device detects the leaking of electricity and trips to prevent shock and other damage to the human and electrical systems.
Medium Voltage & High Voltage Circuit Breaker Timers
Medium voltage is defined as 1KV–69KV, whereas High Voltage is defined as 69KV–230KV. Medium voltage and high voltage circuit breakers (CBs) have different names because of their operating voltage levels.
Vacuum Circuit Breaker Timer (VCB)
Timer for the vacuum circuit abbreviated “VCB.” The VCB or circuit timer is utilised in Medium Voltage settings. A vacuum is created inside the bottles of VCBs to operate the contacts and arc quenching.
Sf6 Circuit Breaker Timer
SF6 circuit breaker timers supplied by circuit breaker timer supplier in India are also commonly employed in medium voltage settings. SF6 gas is used to quench the arc in this breaker because of its efficacy. Even though SF6 Breakers are the most effective in quelling arcs, they are not widely used because SF6 is a hazardous gas that poses risks to humans and the environment.
Oil Circuit Breaker Timer (OCB)
In the oil circuit timer exported by the circuit breaker timer exporter in India oil was employed as the arc quenching medium, and circuit timers were used on high voltages.
Safety precautions to be used while using the machine-
•The main breaker must be turned off and the panel isolated before any work can be done on the circuit timer. This must be done before work on the breakers, including routine checks for wear and tear.
•Personal protective equipment (PPE) should be worn whenever there is even the slightest likelihood of an arc flash hazard (PPE). Arc flash hazards can be determined by the equipment’s design and the presence of sensitive circuit components. Check the installation date and quality of the setup as well.
• Verify that your selected breaker will fit in the existing panel. The amperage rating and compatibility of the wire should be double-checked. Consult professionals if you are unsure of the type of breaker circuit you require.
• Before installing a new Contact Resistance Meter, make sure all your tools, cables, and new components are in good working order. You’ll save time in the long run and guarantee that all connections work correctly with these fast checks.
•If the main breaker is turned off, the main bus bar may still be live and dangerously hot to the touch. The wires entering the panel may be similarly vulnerable. Precautions should be taken at all times, and the correct equipment and methods should be used whenever possible.
