T21-62-15.0A-01-31AL-V

T21-62-15.0A-01-31AL-V circuit breakers provide a variety of solutions suitable for different application fields and use cases. T21-62-15.0A-01-31AL-V is often used in heavy-duty industrial and commercial applications.

The T21-62-15.0A-01-31AL-V circuit breaker is designed with a versatile adjustable current range in addition to its fixed current rating which can be optionally set to protect electrical systems from overloads or short circuits. The adjustable current range makes this model particularly suitable for applications where the current load varies often and quickly, or where the current rating of the system needs to be adjusted per customer specification.

Its rated voltage is usually below 600V AC and for ratings of up to 400A it is mostly used for three phase systems. The tripping characteristic of the T21-62-15.0A-01-31AL-V is adjustable to three levels: electronically adjustable, thermally adjustable and fixed. The adjustable models allow for manual or remote adjustment of the tripping thresholds.

The working principle of the circuit breaker is quite simple and is based on a combination of mechanical and electrical components. It consists of two main parts: the current limiting mechanism, which is responsible for limiting the current that passes through the breaker, and the trip potentiometer. The trip potentiometer detects when the current-limiting mechanism reaches its set limit and trips the breaker.

The circuit breaker works by detecting the short circuit and cutting off power supply to the connected device in order to prevent further damage to the electrical system. This can be done by one of three different mechanisms: magnetic, thermal or electronic. In all cases, as soon as a short circuit occurs, the relevant mechanism immediately triggers the breaker to shut off the power supply. Overload protection works in a similar way; the current flow is monitored, and if the limit is exceeded, the breaker will trip to protect the electrical system.

T21-62-15.0A-01-31AL-V circuit breakers provide a reliable and safe way to protect electrical equipment and systems, making them ideal for use in a range of high-voltage and heavy-duty applications. These breakers are an essential part of any electrical system, ensuring safe and reliable protection in even the most demanding applications.
