The Electrical Products Produced By Our Company are Mainly of the Following Types:

Leakage circuit breaker

Circuit breakers can be used to distribute electrical energy, start asynchronous motors infrequently, protect power lines and motors, and automatically cut off circuits when they experience serious overload, short circuit, undervoltage, and other faults. Their function is equivalent to a combination of fuse type switches and over/under heat relays. And generally, there is no need to change the components after disconnecting the fault current. It has been widely applied.

 

Palm switch

Clapping switch sensor is a switch device based on the working principle of capacitive sensors. Its structure consists of two electrode plates and a layer of dielectric. When touched by hand, the capacitance between the two electrode plates will change due to the presence of the human body, thus achieving the connection or disconnection of the circuit. The clapping switch sensor uses the human body as the electrode of a capacitor, and utilizes the natural conductivity of the capacitor sensor to achieve switch control.

Benefits of Electrical
 

Leakage circuit breaker

Anti-electric shock: ELCBs protect people from potentially fatal electric shocks by detecting leakage currents and interrupting the power supply.

 

Reduced risk of fire: ELCBs minimize this risk by interrupting the power supply in the event of a ground fault.

 

Equipment protection: ELCB can prevent damage to electrical equipment and devices by interrupting the power supply in the event of a fault.

 

Increased safety: ELCBs contribute to the overall electrical safety of homes, offices, and industrial facilities by monitoring circuits.

Reducing the risk of accidents: One of the primary benefits of ergonomic palm buttons is their ability to improve operator safety. By requiring both hands for machine activation, they ensure operators’ hands stay clear of hazardous areas, minimizing the risk of accidental injuries.

 

Enhancing workplace safety by reducing fatigue: In addition to safety, ergonomic palm buttons significantly reduce operator fatigue, a common concern in manufacturing settings. Prolonged, repetitive tasks can lead to physical strain, discomfort, and even injuries, which affect productivity. The design of ergonomic palm buttons helps minimize the effort required for machine activation, allowing operators to work more comfortably over long periods.

FAQ

Q: How does an ELCB work?

A: ELCBs monitor the balance of electrical current between the hot and neutral wires. If a current leaks to the ground, disrupting this balance, the ELCB detects the difference and trips, which disconnects the circuit. Modern versions, also called Residual Current Circuit Breakers (RCCBs), utilize current sensing rather than the voltage sensing used in older ELCBs.

Q: What are the main functions of an ELCB?

A: ELCBs primarily protect against electric shock hazards and prevent fires caused by earth leakage faults. They detect small stray voltages on equipment enclosures and interrupt the circuit if the voltage is dangerous. Some advanced ELCBs may also include overload and short-circuit protection, even though their main function is leakage protection.

Q: What is the difference between an ELCB and a Miniature Circuit Breaker (MCB)?

A: MCBs protect against overcurrents like overloads and short circuits, which protects wiring and equipment. ELCBs are specifically designed to protect against earth leakage currents that can cause electric shocks.

Q: What is the sensitivity rating of an ELCB?

A: The sensitivity rating, or leakage current rating, is the minimum leakage current an ELCB detects before tripping. Common sensitivities are 30 mA for personnel protection and higher ratings for fire protection. Medium-sensitivity ELCBs range from 30 to 300 mA for applications where slightly higher leakage is acceptable.

Q: Are there different types of leakage circuit breakers for different applications?

A: Yes, specialized types exist, in addition to the standard ELCB (RCCB or RCD). Residual Current Circuit Breakers with Overcurrent Protection (RCBOs) offer protection against both earth leakage and overcurrents, which is suitable for limited spaces or when dual protection is needed. Other types vary in sensitivity and features like arc fault protection.

Q: Can ELCBs protect against overcurrent and short circuits?

A: ELCBs and RCCBs do not directly protect against overcurrent and short circuits. Their main function is earth leakage detection. An MCB or fuse is usually needed for overcurrent and short-circuit protection, or an RCBO which integrates both. However, some leakage circuit breakers may include combined features like short-circuit protection.
