Circuit Breakers: LELK2-30482-2-V Application Field and Working Principle

Introduction

Circuit breakers are a critical part of any electrical system. They are used to protect circuits from overloads and short circuits. The LELK2-30482-2-V low voltage air circuit breaker is one type of circuit breakers. It has many applications and a unique working principle depending on its design. This article will explain the application field and working principle of the LELK2-30482-2-V low voltage air circuit breaker in detail.

Application Field of LELK2-30482-2-V

The LELK2-30482-2-V is a manually operated, low voltage air circuit breaker. It is designed for applications where manual circuit protection is desired. The breaker can be used in numerous applications, including off-shore and marine applications, mining operations, and electrical installations in rural and urban areas. Its low-voltage rating makes it suitable for use in most residential, commercial, and industrial applications.The breaker has an adjustable overcurrent protection feature that can be used to protect loads from surges. It also has a trip-free mechanism that prevents accidental tripping of the breaker when the circuit is overloaded. Furthermore, the breaker is equipped with a maintenance-free Operation and Automatic Reset feature, providing reliable protection without the need for manual resetting. Furthermore, the breaker is available in a variety of sizes, making it suitable for a variety of applications, from small installations to large industrial applications. It also has an interchangeable contact system and can be adapted to customer-specific requirements.

Working Principle of LELK2-30482-2-V

The LELK2-30482-2-V low voltage air circuit breaker is a manually operated breaker. It works by automatically detecting an overload or short circuit in the circuit it is protecting. When this is detected, an air interrupter housed within the breaker is automatically tripped, cutting the electricity supply. The breaker is equipped with two different tripping mechanisms, one activated by temperature and one activated by current. The thermal tripping mechanism is triggered when the temperature of the device exceeds a set limit. This is usually caused by an overload in the circuit, or when the circuit is drawing too much current. The current-based tripping mechanism is triggered when the circuit is drawing more current than what is allowed in the breaker\'s rating. The breaker is also fitted with an adjustable overload protection device, which can be used to protect the circuit in case of an overload or a short circuit. The device will automatically disconnect the circuit when the current level reaches the specified limit.The breaker is available in both auto-reset and manual-reset versions. The auto-reset version will automatically reset after the short circuit or overload has been cleared, while the manual-reset version requires manual instructions for resetting.

Conclusion

The LELK2-30482-2-V low voltage air circuit breaker is a reliable and effective device designed to protect circuits from overloads and short circuits. It has a wide range of applications and can be adapted to customer-specific requirements. Additionally, the breaker is equipped with two different tripping mechanisms, one based on temperature and one on current levels. It is also fitted with an adjustable overload protection feature, which can be used to protect the circuit even in the event of an overload or short circuit.
