Introduction to PR11-42-15.0A-XX Circuit Breakers
Application Field
PR11-42-15.0A-XX circuit breakers are one of the most trusted products in the European market, specifically designed for AC operation in circuits with a rated current up to 15 A and a rated voltage not exceeding 250 Vac. It is highly suitable for residential, industrial, and commercial applications and is often found in separators, emergency systems, recharging systems, etc. These miniaturized circuit breakers feature a range of desired attributes, including high protection, reliability, and safety, along with a unique design that fits into any given space.
Working Principle
The PR11-42-15.0A-XX circuit breakers employ a thermal-magnetic operation principle. The warm current is coupled with the existing magnetic field in the conductor to create tripping of the breaker. This operation principle works by:

• First, the current flows through the breaker, which then magnetizes it.
• As the magnetic field and hot current continue to flow, the breaker’s contacts begin to move.
• The internal circuitry detects the change in contact positions and activates the tripping mechanism.
• The tripping mechanism opens the breaker’s contacts, cutting off the flow of power.

The PR11-42-15.0A-XX circuit breakers feature a unique design wherein the design of the trip current is optimized to precisely match the expected loads. This helps to ensure that the breaker trips only when there is a dangerous level of current and not just any small surge. The internal circuitry protects against short circuit and overloads by tripping the breaker within a very short time, often within 30 milliseconds. This fast-response feature ensures that the system is protected in the shortest amount of time.
These miniature breakers are designed for direct current, single-phase, and three-phase circuits. The PR11-42-15.0A-XX also features a cover lock that helps to keep the circuit safe against shocks, moisture, and external objects. There is also a manual reset option that can be used when the circuit needs to be manually reset after a disruption. Moreover, the design of these breakers has been optimized for vibration and shock, ensuring that they remain reliable and perform optimally even in high-vibration environments.
Conclusion
The PR11-42-15.0A-XX circuit breakers are reliable and trustworthy products that offer excellent protection and safety for residential, industrial, and commercial applications. They intelligent design helps to optimize the current tripping response time without disrupting the flow of power. The cover lock and manual reset options provide additional protection against external elements, shocks and moisture damage. Outstanding features include vibration and shock resistance, making them an ideal choice for high-vibration applications.
