LELHPK11-1REC4-32412-150-V Circuit Protection

Circuit breakers are important fixtures in most large-scale electrical installations, providing overload protection, electrical fault protection, and general switch-off capabilities within large electric power networks. The specific circuit breaker in question, LELHPK11-1REC4-32412-150-V, is designed for high voltage electrical protection in power distribution and transmission, either indoor or outdoor.

This circuit breaker operates at an operating voltage of 150 volts, with 22kV maximum voltage. It is provided with four different fixed setting times to guarantee the correct setting for each application. This means it can be adjusted to suit any application, from residential to industrial. A variety of additional accessories, such as inclining units, can be purchased and attached to the circuit breaker for additional flexibility.

In terms of its working principle, the LELHPK11-1REC4-32412-150-V operates in a very specific way. In general, the components of a circuit breaker are divided into two main parts: an arc chamber and a current limiting device. The arc chamber contains a number of small contacts which temporarily bridge the high voltage gap between two electrodes. The current limiting device then detects the current overload and triggers the circuit breaker. This causes the contacts to rapidly expand, creating a protection barrier between the two electrodes. This protects the electrical system from a dangerous current overload.

In normal operation, the LELHPK11-1REC4-32412-150-V is switched on before the current reaches the protected electrical system. This is accomplished through the interlocking switch which is built into the arc chamber. When the electrical system is powered on, the contacts within the arc chamber remain closed. The current is then sent through the current limiting device, causing it to trip and break the circuit.

In terms of its applications, the LELHPK11-1REC4-32412-150-V is suitable for both indoor and outdoor installations. This makes it a great option for protecting a variety of electrical systems, from residential to commercial and industrial buildings. More specifically, it is most commonly installed in power plants, substations, wind turbines, and other high voltage installations. It is also suitable for use in data centers and other information technology installations.

Due to its design and features, the LELHPK11-1REC4-32412-150-V is well-suited for its intended applications. Its compact size, high voltage rating, adjustable settings, and other accessories make it a great choice for a range of power distribution and transmission applications. With its impressive performance, flexibility, and durability, the LELHPK11-1REC4-32412-150-V is an excellent choice for anyone looking for an economical and reliable circuit breaker.
