IELHB111-1REC5-70303-15 Circuit Protection

Circuit Breakers

The IELHB111-1REC5-70303-15 is a type of circuit breaker which is designed to protect an electrical system from damage caused by overloads or short circuits by disrupting the flow of electrical current. Circuit breakers are found in both domestic and industrial applications, and they provide a much more effective means of protection than old-style fuses. In this article we will discuss the application field, operation and working principle of the IELHB111-1REC5-70303-15.

Application fields

The IELHB111-1REC5-70303-15 is typically used in large industrial circuits requiring a high level of protection. It is commonly used in heavy-duty industrial machines such as generators, reactors and motors, as well as in the protection of smaller office and residential applications. In addition, the IELHB111-1REC5-70303-15 can be used in a variety of difficult to access areas where space is limited, because of its slim size. It is also suitable for hazardous environments and environments with a high level of EMC (electromagnetic compatibility).

Operation

The IELHB111-1REC5-70303-15 operates in a similar way to traditional fuse-type circuit breakers. When an overload or short circuit occurs, the breaker trips and interrupts the flow of electricity, thus preventing damage to the electrical system or device. The breaker can be reset manually, by flipping a switch or pushing a button, once the fault has been corrected. It is important to note that the breaker must be reset before the device or system can be operated again.

Working Principle

The IELHB111-1REC5-70303-15 is equipped with a thermal magnetic trip device, which allows it to react to both overloads and short circuits. An overload is detected when a current is detected which is significantly higher than normal, while a short circuit is detected when electrical flow is blocked or reduced. The thermal-magnetic trip device works using a combination of heat and magnetism to detect changes in current. When a fault is detected, the breaker trips within milliseconds, thus interrupting the flow of current and preventing further damage.

In conclusion, the IELHB111-1REC5-70303-15 circuit breaker is designed for a variety of applications, including heavy-duty industrial machines and residential installations. It works using a combination of thermal and magnetic trip devices to detect changes in current and react accordingly. This quick and effective response provides protection from damage caused by overloads and short circuits.
