The SWOM1 series plastic shell circuit breaker adopts the form of a thermal magnetic release; This product has superior performance such as beautiful appearance, compact structure, long service life, low rated power consumption, stable performance, and convenient installation, providing users with safe and reliable protection.
This circuit breaker has isolation function.
With O and OFF position indication, the handle indicates the O and OFF positions when the contact is opened; The indicated position of the rotating handle or operating mechanism is consistent with the body, which will not affect the reliability of the product.
The circuit breaker can be installed vertically (i.e. vertically) or horizontally (i.e. horizontally).
With current limiting capability, the entire series is designed with a current limiting action mechanism, which extinguishes the arc before the expected short-circuit current reaches its peak, reliably suppressing the impact of short-circuit current on the circuit. The diagram shows the actual breaking short-circuit current peak and expected short-circuit current peak curve indicators of the current limiting action mechanism.

Circuit breakers have various protection functions (overload, short circuit, undervoltage protection, etc.), adjustable action values, strong breaking capacity, easy operation, safety, and other advantages, so they are currently widely used;
2 circuit breakers can be used to connect and disconnect load circuits, as well as to control infrequently started motors. Its function is equivalent to the sum of some or all functions of knife switch, overcurrent relay, voltage loss relay, thermal relay, Residual-current device and other electrical appliances, and it is an important protective appliance in low-voltage distribution network;
3. The circuit breaker is relatively precise internally, but the principle is very simple. It connects inductors in series between the incoming and outgoing lines, and when the current exceeds the rated value, the coil drives the iron core for protection action;
4. The dynamic and static contacts and contact rods of the circuit breaker are designed in a horizontal shape, utilizing the electric repulsion generated by short circuits to disconnect the dynamic and static contacts, with high breaking capacity and strong current limiting characteristics;
5. The arc extinguishing chamber of the circuit breaker adopts a metal grid structure, and the contact system has a repulsive current limiting mechanism, which has high breaking and current limiting capabilities;
6. The circuit breaker has a double release. The inverse time action is that the Bimetal is heated and bent to make the release act, and the instantaneous action is that the core armature mechanism drives the release act. There are two types of tripping methods: electromagnetic and double tripping;
8. Modular circuit breaker accessories, easy installation, and reliable protection;
9. The circuit breaker has an overload alarm function without tripping. When an overload alarm occurs, the circuit breaker will not trip and the main circuit will continue to open to ensure power supply safety.
