Circuit Breakers: UPG66-1REC5-34679-2

Circuit breakers are one of the most important components in modern electrical systems. In order to protect against damage caused by electrical faults, it is essential that circuit breakers trip in accordance with their rated operation parameters. The UPG66-1REC5-34679-2 model of circuit breaker is a bi-metallic trip unit, designed for energy monitoring and protection. It has two distinct application fields and working principles.

Application Field: Single-Pole AC Thermal-Magnetic Circuit Breakers

This circuit breaker is suitable for use in single-pole AC thermal-magnetic circuit breakers up to 63A, with speeds of up to 1000V AC/DC. This type of circuit breaker is primarily used for current limitation and protection. It has two main operating principles, thermal-magnetic and static. On the thermal-magnetic side, the circuit breaker monitors the current passing through the circuit and trips when the current reaches a pre-set level. On the static side, the circuit breaker trips when the voltage in the circuit reaches a pre-set level.

Application Field: Three-Pole DC Thermal-Magnetic Circuit Breakers

This circuit breaker is also suitable for use in three-pole DC thermal-magnetic circuit breakers up to 63A, with voltage of up to 1000V AC/DC. Just like the single-pole AC thermal-magnetic circuit breaker, it operates on two main principles: thermal-magnetic and static. On the thermal-magnetic side, the circuit breaker monitors the current passing through the circuit and trips when the current reaches a pre-set level. On the static side, the circuit breaker trips when the voltage in the circuit reaches a pre-set level.

Working Principle of UPG66-1REC5-34679-2 Circuit Breakers

The working principle of the UPG66-1REC5-34679-2 circuit breaker is based on the electromagnetic principle of energy conversion. The internal components of the circuit breaker convert electrical energy into mechanical energy. This energy is then used to open and close the contacts of the circuit breaker, which enable current to pass through the breaker.When the current passing through the breaker exceeds the rated load of the breaker, the contacts will open, or \'trip\'. This interrupts the circuit to stop it from drawing too much power and causing damage to the electrical system. The trip point of the breaker can be adjusted by modifying the spring tension of the breaker.

Conclusion

The UPG66-1REC5-34679-2 circuit breaker is an essential component for any electrical system. It can be used in both single-pole and three-pole AC and DC thermal-magnetic circuit breakers, providing both current limitation and protection. Its working principle is based on the principle of electromagnetic energy conversion, where it converts electrical energy into mechanical energy in order to trip the circuit breaker. With its adjustable trip point, this type of circuit breaker is ideal for protecting circuits from the dangers of drawing too much power.
