Circuit breakers are essential components not only in the electrical system of various vehicles but also in industrial and commercial settings. They help protect machinery and other electronic components from power surges, prevent wiring from overloading, allow simultaneous switching of multiple circuits, and offer manual and automatic overcurrent protection. The UPL1-1-72-203 is one such circuit breaker, a three-pole device part of the UPL Series.

The UPL1-1-72-203 has a rated operating current of 72A and a rated operating voltage of Ue 400V. Additionally, it has a rated short circuit capacity of Icu 65kA. Constructed of superior quality material, the device is thermal-magnetic and equipped with a single-phase trip function, eliminating the need for external relays. Another notable feature of UPL1-1-72-203 is its ability to provide simultaneous indication of three poles’ status.

Typically, UPL1-1-72-203 circuit breakers are used in residential, commercial and industrial applications, such as motor, compressor and lighting circuits. In an industrial setting, they are usually installed in power and control control panels for monitoring and controlling the electric currents running through various electric circuits.

The working principle of UPL1-1-72-203 is based on the “thermal-magnetic” principle. Whenever the electric current running through the circuit exceeds the rated current, the breaker detects the current by virtue of a “thermal memory” and triggers the release of a switch-off tripping element. This interrupts the current supply and thus protects the electric circuit from an overload or a potential short circuit. Moreover, the magnetic element reacts to an overload faster than the thermal element. Therefore, UPL1-1-72-203 offers dual protection.

Apart from offering all-round protection and insulation, the UPL1-1-72-203 circuit breaker features high efficiency, reliability, flexibility and convenience. It is designed in accordance with IEC and CCC standards, assured of performance and safety. With these features, UPL1-1-72-203 is truly among the best circuit breakers available in the market.
