2-5200-H-5A Circuit Breakers

Circuit breakers are key components in electrical systems and are designed to protect circuits from overload or short-circuits. The 2-5200-H-5A model of circuit breaker is an industrial-grade breaker used to control and protect high current circuits from overload or short-circuits. It features an adjustable current setting and an instantaneous trip action design for quick circuit shutoff.

Application Field

The 2-5200-H-5A is suitable for use in a wide range of applications such as electric power plants, construction, industrial, commercial and residential buildings. It is an ideal choice for monitoring circuits that draw high currents such as:

• High electric power machines
• Transformers
• Generators
• Motors
• Large fluorescent lighting fixtures

The 2-5200-H-5A has a range of adjustable current settings, and can be adjusted to match the system rated current with an accuracy of +/- 10%. This makes it highly suitable for industries that have fluctuating current draw.

Working Principle

The working principle behind the 2-5200-H-5A circuit breaker is based on a thermal-magnetic mechanism, which uses both a current threshold and a temperature threshold to control the flow of electricity. When the current drawn from the circuit rises above the set current threshold, a bi-metallic strip in the breaker heats up and begins expanding, thus triggering the circuit breaker’s trip mechanism. This mechanism trips a contactor, which disrupts the flow of electricity, thereby protecting the circuit.

In addition, when the temperature of the breaker reaches a certain temperature threshold, the bi-metallic strip will expand enough to trip the breaker, even when the current threshold is lower than the rated current. This offers an additional level of protection, by allowing the breaker to trip even when the current draw is low.

The 2-5200-H-5A also features an instantaneous trip action design, which allows the breaker to trip within a few milliseconds after the current threshold is exceeded, thereby minimizing any surge damage to the system.

Overall, the 2-5200-H-5A is a highly reliable and robust breaker suitable for a range of applications, and is a key component in any electrical system.
