515DC-6 is an electric circuit breaker manufactured by GLM China. It is a miniature circuit breaker with a working current of 0.5A. It has an insulation voltage of 1400V AC. It is mainly used in a heavy electric power system to provide circuit switching or short-circuit protection, prevent fire and equipment damage, control over-current and overload. The 515DC-6 circuit breaker is designed with a wide range of applications and working principles.

The 515DC-6 has 4 application fields. Firstly, it is used for single phase circuit protection in electric power distribution and motor protection. It provides short circuit and overload protection, and has the function of delayed current release. Secondly, it can be used in electric power equipment, such as lighting lamps, switches, sockets and so on. Thirdly, it can be used on home appliances, such as electric water heaters, air conditioners and TV sets, to prevent fire caused by overload. Lastly, it is also used in industry areas such as motors, transformers, elevators, pumps, etc. for protections.

The 515DC-6 working principle of the circuit breaker is defined by the standard EN 60898-1. In normal cases, the circuit breaker is in a closed state. When the network is normal, the current passes through the circuit breaker without any effect. But when there is an electric overload, short circuit or ground fault, the magnetic fields generated by the movement of these currents act on the operating mechanism, making the operating mechanism open the contacts. With the opening of the contacts, current is interrupted, and the circuit breaker tripped. Besides, the 515DC-6 circuit breaker supports a delayed current release, which is triggered when the current drops to the predetermined release value. This is to give the equipment or motor a running time for safe shut-off.

The 515DC-6 circuit breaker is a system that provides high reliability in a variety of applications. Its working principle and application fields comply with the standard EN 60898-1. It provides reliable protection against overload, short circuit and fire incidents. The delayed current release ensures the safe operation of the equipment and motor. With its compact size and wide range of applications, the 515DC-6 circuit breaker is one of the most popular products in the market.
