Circuit Breakers are indispensable safety devices for use in any type of electrical power system. The IUGBX11-32036-2R25 is a breaker with an adjustable short-circuit protective function. This circuit breaker is suitable for indoor installation in medium-voltage switchgear and can trip quickly at a preset current value, providing reliable protection from overloads and short-circuits.

Application Field

IUGBX11-32036-2R25 circuit breakers are commonly used in electricity supply companies and residential, industrial and commercial power networks. It is suitable for isolating and switching circuits in AC 50Hz or 60Hz, a rated voltage of 3.6 kV to 12 kV and a rated current of 630A and below. Additionally, it is capable of disconnect and short-circuit protection for transformers, generators, motors, capacitors and other three-phase circuits in the electrical power system. Its high breaking capacity and protection level make it suitable for use in systems with low short-circuit current.

Working Principle

The IUGBX11-32036-2R25 circuit breaker has three phases equipped with two pairs of contacts. When a fault occurs, the contact breaker trips an electromagnet to open the contacts, interrupting the electrical power flow. This procedure is called tripping, and when the fault is resolved, the contact breaker can be reset manually or automatically (depending on the system).

The circuit breaker is designed with adjustable short-circuit protective functions. When the short-circuit current reaches the preset current value, a relay trips the contact breaker and the current is interrupted. These adjustable protective functions can be tailored to meet specific requirements. For example, the trip and reset current values can be adjusted to increase or decrease the sensitivity of the device.

In addition to short-circuit protection, the IUGBX11-32036-2R25 circuit breaker also has an overload protection feature. If the current is greater than the maximum rated load current, a relay will trip the contact breaker and interrupt the current. This prevents overloads from damaging the electrical system.

The IUGBX11-32036-2R25 is a reliable and durable circuit breaker, designed with a wide range of protective functions. It is suitable for use in a variety of electrical power systems, providing reliable protection from overloads, short-circuits and other faults.
