Chint Circuit Protection with LED Controls

The Chint circuit protection range offers a complete safety solution for homes, commercial buildings and industrial installations. As a trusted Chint distributor, LED Controls supplies a wide selection of devices designed to keep electrical systems safe, compliant and easy to manage.

What is Circuit Protection?

Different devices are designed to protect against different types of faults, such as overloads, short circuits or leakage currents. Chint covers all of these needs with a clear, compatible product family.

What do Chint Circuit Protection products do?

Circuit protection means preventing damage, fire risk and electric shock. Electrical systems can fail in a few common ways: Too much current (overload), sudden surges (short circuits), or earth leakage (which can cause electrocution). Chint devices are designed to detect specific issues and automatically switch off the power before damage or injury occurs:

• MCBs protect cables and circuits from overload and short circuit
• RCDs detect earth leakage which can cause electric shock or fire
• RCBOs combine both functions in one device
• MCCBs provide heavy-duty protection for larger systems and higher currents

Chint MCB: everyday circuit protection at LED Controls

The Chint MCB range is their most popular protection device. Often used in consumer units, distribution boards and control panels to protect individual circuits such as lighting, sockets or small equipment. Chint MCBs are available in a range of different sizes and trip types, which means they can be matched to everything from simple domestic circuits to more demanding commercial loads.

• Breaking capacity options: 6kA or 10kA
• Current range: 1A - 125A
• Available poles: 1P, 1P+N, 2P, 3P, 3P+N and 4P
• Trip curves: B, C and D for different load types
• Voltage: typically 230/400V AC (50/60Hz), with some models supporting DC applications up to around 110V

Chint RCD: shock protection at LED Controls

Chint RCDs are designed to protect people from electric shock. They monitor the flow of electricity and cut the supply almost instantly if they detect current leaking to earth, which could indicate a fault or someone coming into contact with a live part.

• Current ratings: from 25A up to 100A
• Sensitivity options: 30mA, 100mA and 300mA
• Available poles: 2 pole and 4 pole
• RCD types available: Type AC, Type A, time-delay Type A and Type B
• Standards: compliant with IEC/EN standards for residual current protection
• Frequency: designed for 50/60Hz AC systems

Smaller devices sensitive to 30mA leakages are generally used for personal protection, while higher ratings such as 100mA and 300mA are usually used for fire protection in high-power systems or to provide discrimination, meaning only part of the system trips instead of everything at once.

Type AC RCDs are suited to basic loads, while Type A devices are used where equipment may produce pulsed DC currents, such as modern electronics. Type B RCDs are designed for more advanced applications where smooth DC currents may be present, such as EV charging or industrial systems.

Time-delay RCDs are used upstream in a system to prevent nuisance tripping and allow downstream devices to operate first, improving system reliability. Altogether, Chint offers a comprehensive range of Residual Current Devices, allowing you to tailor your circuit protection system to the specific requirements of your application.

Chint RCBO: combined protection at LED Controls

A Chint RCBO combines the functions of an MCB and an RCD into a single unit, meaning it protects both your circuit and YOU at the same time.

• Breaking capacity options: 6kA and 10kA
• Current ratings: from 6A up to 50A (depending on model)
• Sensitivity: typically 30mA for personal protection
• Available formats: 1P+N, 2P and 3P+N
• RCD types available: Type AC and Type A
• Compact sizes: options available in 18mm and wider modular formats
• Standards: compliant with IEC/EN standards for combined protection devices
• Frequency: designed for 50/60Hz AC systems

Chint MCCB: larger system protection at LED Controls

Chint MCCBs are designed for higher power applications where standard MCBs won't do. These devices are used to protect main supplies, large distribution boards and heavy electrical equipment. MCCBs work in a similar way to MCBs, but are built to handle much higher currents and fault levels. They can also be adjusted to suit the specific requirements of your system, making them ideal for commercial and industrial installations.

• Current ratings: from 16A up to 1250A
• Breaking capacity: typically 50kA
• Available poles: 3 pole and 4 pole
• Trip types: thermal magnetic and electronic adjustable protection
• Frame sizes: multiple frame options including 125A, 250A, 400A, 630A, 800A and 1250A
• Voltage: designed for up to 415V AC systems
• Standards: compliant with IEC/EN 60947-2
• Additional features: isolation function, current limiting, zero arcing design and compatibility with a wide range of accessories
