Circuit Breakers (CBs) are essential protective devices used in electrical systems to ensure the safety of equipment and lives. T21-2-20.0A-01-31AL-V is a specific CB, a Miniature circuit breaker with a rated current of 20.0A and a rated voltage of 400V and featuring a thermal-magnetic release. This CB can be used in domestic and industrial applications.

The working principle of the T21-2-20.0A-01-31AL-V is based on two main components: a thermal element and a magnetic element. The thermal element responds to an overload or short circuit, disconnecting the overload circuit. The magnetic element has a bimetallic strip that reacts to a short duration overcurrent, establishing an arc and opening the circuit.

The T21-2-20.0A-01-31AL-V offers protection from overcurrent, thermal and short circuit. Specifically, the CB features a tripping curve of B or C and a long-time and instantaneous release as well as adjustable trip current. This CB has a high short circuit breaking capacity and low leakage current, making it suitable for both domestic and industrial applications.

In domestic applications, the CB is applied for protection against overloads, short circuits and thermal protection of circuits. It can also be used for fuse protection in sources of renewable energy and electrical installations. In industrial applications, the CB is used for motor and transformer protection, as well as power, control and distribution systems. The T21-2-20.0A-01-31AL-V CB has a long trip time which is ideal for industrial applications, where it can prevent unnecessary interruption of operations in the event of a short circuit or overcurrent.

Overall, the T21-2-20.0A-01-31AL-V Miniature circuit breaker offers superior safety and reliability in a single package and is suitable for a variety of domestic and industrial applications. Its high breaking capacity, long trip time and low leakage current make it a versatile and reliable protective device.
