Thermal Magnetic Circuit Breakers
Thermal magnetic circuit breakers are auto-operate protective switches designed to protect against overloads or short-circuits in electrical circuits. These breakers feature electromagnets and bimetallic strips to detect electrical surges. These thermal aspects of devices allow for larger and delayed overloads, such as in the case of motors with small overloads each time the engine is switched ON for a short period of time. This avoids any damage or tripping circuits.
How do they work?
The integrated electromagnet is highly sensitive to higher surges in power currents and responds efficiently by switching OFF the current flow to the component. On the other hand, the bimetallic strip expands upon exposure to excessive current flow that causes bending of the strips towards a trip bar and turns the circuit OFF. These strips return to a normal state, allowing the operation to become routine and continue when cooled down and reset.
Typical Specifications of Thermal Magnetic Circuit Breakers:
These dual operating breakers feature several unique characteristics needed to identify them when operating:
-
Mounting style:
It designates various options such as draw-out, bolt-on, fixed, plug-in, and DIN rail mounts.
-
Rated AC voltage:
It demonstrates the maximum AC voltage that these breakers are designed to handle.
-
Rated breaking capacity:
It describes the breakers’ broken current at a given recovery voltage under specified conditions.
-
Continuous current rating:
Demonstrate the maximum amount of continuous current that breakers can handle without tripping.
-
Operating temperature:
It indicates the optimum operating temperatures for these specified breakers.
-
The number of poles:
It shows the circuit number that the breaker can control.
-
Short-time rating:
It illustrates the amount of fault current thermal-magnetic breakers can carry during closing conditions.
Applications of Thermal Magnetic Circuit Breakers:
Thermal magnetic circuit breakers are ideal for a wide range of distribution boards.
They are found in the subsidiary circuits in several electrical supply, telecommunications, and process control systems to protect against overloads.
