Circuit Breakers

1626-2-15A application field and working principle

Circuit breakers are electrical devices designed to protect an electrical circuit from overload and short circuit. Among various types of circuit breakers, 1626-2-15A is a versatile and reliable model for automation and protection circuits. This article provides a brief overview of 1626-2-15A’s application fields and a general description of its working principle.

Application fields

The 1626-2-15A uses a fixed-set trip current and functions as an economic, cut-off switch for overloads and short circuits. With its circuit breakers, power supply is readily available and interrupted in the event of a serious fault condition. This makes it particularly suitable for industrial equipment, mining equipment, welders, throttle and boosting circuits, rail application, and electroplating and chemical equipment.

Working Principle

The 1626-2-15A works by attempting to measure current to determine if it is within typical limits, and if not, cutting it off. The working principle is as follows. A mechanical actuator is secured in a frame. This actuator is opened or closed via an electricspring-openductor mechanism, depending on whether the load current is within acceptable limits. Inside the actuator, a bi-metallic strip is exposed to the current. As the current fluctuates and begins to exceed standard limits, the bimetallic strip will curl or separate to activate the electrical actuator. This will cause the breakers contacts to open, thus cutting off the current supply to the protected circuit.

An additional protection feature is provided via a heater in the mechanism. This heater will be activated in the case of extended overloads and will, in turn, activate a trip mechanism in the case of extended fault conditions, regardless of the current. When the heater is activated, it will heat up the bimetallic strip, thus causing it to curl or separate and activate the breaker\'s contacts, as explained previously.

Conclusion

The 1626-2-15A is an reliable and versatile circuit breaker that is suitable for any application where the overcurrent and short-circuit protection of electrical circuits is required. It works by measuring current to determine if it is within acceptable limits, and if not, cutting off the current. This is accomplished via an electrical actuator that is exposed to a bi-metallic strip, which in turn activates and deactivates the circuit breaker\'s contacts as necessary. In addition, a heater-activated trip mechanism is provided as an additional protection feature.

This article has provided a brief overview of 1626-2-15A’s application fields and a general description of its working principle. This device is an important component in many electrical circuits, as it can provide safety and dependability in the case of potential overloads and short circuits.
