IPA-1-1-52-1.00-A-01-T

Circuit breakers are a type of electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. The IPA-1- 1 -52-1.00- A -01-T is a specific type of circuit breaker, equipped with not only a thermal-magnetic trip unit, but also a special phase balancing resistor.

This breaker is typically used in high-voltage power distribution systems. It can distinguish between overloaded circuits and short circuits, allowing for faster and more accurately responsive protective switching of lines. The trip unit also offers an adjustable phase balancing resistor to ensure even protection across multiple phases and a variable frequency overload protection curve to provide the most reliable and accurate performance.

The working principle of the IPA-1-1-52-1.00-A-01-T circuit breaker provides the power system designer with a wide range of protection options. The breaker utilizes a combination of thermal and magnetic tripping units to quickly identify any overload or short circuit condition, while the adjustable phase balancing resistor provides even protection across multiple phases.

In the event of an overload, the thermal unit will detect an increase in current and activate a trip mechanism. The breaker will then break the circuit, preventing any further damage to the power system. If a short circuit is detected, the magnetic unit will activate the trip mechanism and open the circuit before it causes any damage.

The adjustable phase balancing resistor ensures the protective performance remains consistent, regardless of frequency or phase configuration. This provides more reliable and accurate performance, and gives the power system designer more control over the protective performance of the breaker.

In summary, the IPA-1-1-52-1.00-A-01-T circuit breaker is designed to provide protection against both overload and short circuit conditions. Its adjustable phase balancing resistor ensures consistent and reliable performance, while its variable frequency overload protection curve gives the power system designer more control over the protective performance.
