Circuit breakers have been widely used in industry to protect components and systems from damage, and have been a fundamental component of protecting wealth and safety in the home. 1218B B591000 is a type of circuit breaker, and it has extremely wide applications, as well as an important working principle.

The main application of experimental 1218B B591000 circuit breaker is in the power supply system. It is suitable for A.C. 50 Hz/60 Hz up to 690 V or AC voltage up to 1000 V, and it can be applied in a single pole or three-pole system. It is capable of controlling and breaking the short circuit and overload current circuits. The 1218B B591000 circuit breaker is used to protect the power supply in the motor, elevator, lighting and distribution system, as well as components and systems in the manufacturing industries. It can also be shunted with a non-magnetic arc-extinguishing chamber and be used as a safety breaker.

In terms of the working principle, the 1218B B591000 circuit breaker relies on the combination of an electro-mechanical undercurrent release, a bimetallic strip, and an electromagnetic release. When an overload current takes place, the undercurrent release will switch and act the bimetallic strip which has its own heat. Consequently, the bimetallic strip will shrink and release the contact to cause an overcurrent trip. When it comes to short circuit protection, the 1218B B591000 is equipped with an electromagnetic release. During a short-circuit, the electromagnetic force produced by this release will be triggered, resulting in a booster mechanism inside the circuit breaker which will act to switch off the circuit.

In conclusion, the 1218B B591000 circuit breaker has a wide range of applications, particularly in power supply systems, and its working principle incorporates a electro-mechanical undercurrent release, a bimetallic strip, and an electromagnetic release, to protect the system from overloads and short circuits.
