Circuit breakers are a critical part of an electrical system, since they are designed to protect the system from overloads, ground faults, and short circuits. They provide protection by sensing when there is an increase in current beyond the rated load and automatically disconnecting the circuit from the power source. The QMB-032-00ENN-3BA is a 3-pole miniature circuit breaker used for applications which require a reliable, economical form of overcurrent protection with higher electrical, mechanical, and thermal endurance.
The QMB-032-00ENN-3BA is commonly used for building automation, residential and commercial applications, recreational vehicles, factories or workshops, and more. As a 3-pole device, it has two trip stages (thermal and magnetic overload) for switching and short-circuit currents. This means it can be used in a variety of applications, depending on the customer requirements. It also features a solid-state trip circuit breaker module that is very stable and reliable, and a 10kA short-circuit current-interrupting rating. The breaker is also compact in design and can easily fit into small spaces.
The working principle of the QMB-032-00ENN-3BA is based on similar principles as other types of circuit breakers. When an overcurrent is flowing through the circuit, an increase in temperature is generated. This increased temperature causes a bimetallic strip connected to the back of the breaker to bend and deflect, which in turn causes the contacts to open, and the circuit is then broken. The bimetallic strip and the breaker spring are designed to reset the breaker when the overcurrent is removed. The breaker also contains a magnetic unit that senses when the current exceeds the rated load and causes the circuit to open.
The QMB-032-00ENN-3BA is a very reliable circuit breaker and is perfect for applications where a reliable and economical form of overcurrent protection is needed. Its solid-state trip module provides great stability, and the 10kA short-circuit current-interrupting rating ensures safe operation. The breaker is also compact in size, allowing it to easily fit into small spaces. Overall, the QMB-032-00ENN-3BA is a great choice for a variety of applications that require a dependable and economical form of overcurrent protection.
