IELK11-23257-21-V Circuit Protection

Circuit breakers are a common piece of electrical safety equipment used to protect a ranging number of electrical and electronic systems from being damaged by excessive currents. They are available in a variety of sizes and styles and are commonly used in residential, commercial, and industrial applications. The IELK11-23257-21-V circuit breaker is a general-purpose circuit breaker for medium voltage switchgear applications. The IELK11-23257-21-V circuit breaker is made up of a metal chassis containing an arc deflector, over-current protection, and a control system with a mechanical mechanism connected to the breaker’s levers. The arc deflector is used to reduce the amount of arcing created when the circuit breaker trips. It does this by redirecting the arc away from the contacts and into the air. The over-current protection is a set of resistors and capacitors that limit the amount of over-current flowing through the circuit breaker in order to prevent damage to the device. Lastly, the control system is used to control the trip delay, on-delay, and off-delay of the circuit breaker. The IELK11-23257-21-V is very effective in medium voltage switchgear applications due to its high performance and reliability. It can be installed anywhere from industrial control panels to residential and commercial buildings. It has a rated voltage of up to 3.6 kV, making it ideal for medium voltage switchgear applications. It also has a short-circuit strength of up to 80 kA, making it suitably robust for these kind of applications. In addition, its quick-break feature ensures that the circuit breaker can quickly trip when an over-current situation arises, preventing damage to the electrical system. In terms of working principle, the IELK11-23257-21-V is equipped with two main components: a thermal overload relay and a magnetic trip unit. The thermal overload relay is responsible for detecting when the operating current of the circuit is higher than the rating, and will then activate the breaker to protect the electrical system. The magnetic trip unit is the device that actually trips the circuit breaker when the thermal overload relay detects an over-current situation. Specifically, it initiates a rapid withdrawal of the breaker contacts. This rapid withdrawal prevents damage to the circuit by allowing the current to dissipate in the air instead of flowing through the circuit. The IELK11-23257-21-V circuit breaker is a reliable and high performing device that is suitable for medium voltage switchgear applications. It is composed of an arc deflector, over-current protection, and a control system with a mechanical mechanism to enhance its mechanics. It uses a thermal overload relay and a magnetic trip unit to detect over-current conditions and quickly trip the breaker for protection.
