Circuit Breakers

The 3140-F170-P7T1-SGRX-5A circuit breaker is a device used to prevent overcurrent and protect electrical equipment and wiring from damage. It is an essential piece of safety equipment used in all residential and commercial buildings. This type of breaker is a single-pole circuit breaker, which means it can monitor and protect a single circuit.

Application Field

The 3140-F170-P7T1-SGRX-5A circuit breaker is commonly used in residential and commercial buildings as it is suitable for an internal load center with a power rating up to 50A. It is considered relatively safe to use in areas with high risk of electrical fire, overloads, or shocks. It is recommended for the protection of electronic equipment, motor-driven machinery, as well as for short-circuit and overload protection. As it is suitable to be installed in garages, kitchens, and bathrooms, it is an ideal choice for any place in need of protection.

Working Principle

The 3140-F170-P7T1-SGRX-5A circuit breaker has a magnetic latch mechanism that triggers when there is an excessive current. When the current trips the breaker, the internal bi-metal strip bends, releasing the latch in the process, and thus opening the contact point. This stops the flow of current to the circuit. When the breaker is reset manually, the bi-metal strip will revert to its normal curve, and then the contacts will be bored. Therefore, the circuit will be back in action again.

In addition to the tripping action, it also offers overcurrent protection through a thermal-magnetic relay. This relay has a magnetic coil that creates a magnetic field as soon as it is energized. When the current in the circuit exceeds the rated value, the increased current produces a greater magnetism and heat which will trip the breaker. This results in the breaking of the contact points and thus reducing the flow of current to the circuit.

Advantages

The 3140-F170-P7T1-SGRX-5A circuit breaker has a number of advantages over standard breakers. Firstly, it is designed with a high breaking capacity and therefore offers better protection and safety. In addition, it also offers overcurrent protection, so it can prevent overloaded circuits from damaging the equipment connected to them. Finally, it is also resistant to surge and voltage spikes that can damage sensitive equipment connected to the circuit.

As an all-round solution, it is ideal for residential or commercial applications, offering protection against overcurrent, short-circuits, and overloads. Its high break rate and fast-acting mechanism offer greater protection, while its ability to prevent voltage spikes is an added bonus, making it the perfect choice for any electrical system.
