LELB1-1REC4R-38661-70-V Circuit Protection

Circuit breakers are incredibly important electronics components that help protect wiring and devices from damage or destruction due to overloads or short-circuits. The LELB1-1REC4R-38661-70-V is a specific type of circuit breaker that is designed for a specific purpose. This article will discuss the features and functions of this model, as well as its application field and working principle.

Features and Functions

The LELB1-1REC4R-38661-70-V is a type of circuit breaker that is designed primarily for low voltage motor protection and over-load current protection. It is a 1-pole, 3-phase breaker that is rated at 600 VAC, 70 A. It is part of L.E. Electronics\' Decompact Series of advanced magnetic/thermal circuit protection devices. It offers a variety of features and functions that make it ideal for motor protection.

The LELB1-1REC4R-38661-70-V features self-diagnostics, which means it will monitor its own performance and alert the user if it detects any problems. It also has an adjustable instantaneous trip current, adjustable short-time delay, and adjustable long-time delay. This makes it very easy to customize the breaker to suit a particular application or requirement. The breaker also features a hard-lock switching mechanism, which means when it trips, it remains tripped until manually reset by the user.

Application Field and Working Principle

The LELB1-1REC4R-38661-70-V is designed primarily for motor protection, but it can also be used in other applications where over-current protection is required. It is particularly suited for use in low voltage applications, such as industrial automation equipment, air conditioning systems, and other HVAC systems. In these kinds of applications, the breaker helps protect wiring and devices from damage or destruction due to overloads or short-circuits.

The working principle of the LELB1-1REC4R-38661-70-V is based on electromagnetism. When an excess amount of current passes through the breaker, its electromagnet creates a magnetic field that is greater in strength than the magnetic field generated by the current passing through the circuit breaker. This causes the breaker to trip and shut off the power, thus preventing any further damage to the wiring or device.

The adjustable features of the LELB1-1REC4R-38661-70-V make it possible to customize the breaker to suit a specific application. For example, the adjustable instantaneous trip current allows the user to set a specific threshold for tripping the breaker, and the adjustable short-time delay and long-time delay features allow the user to customize the amount of time the breaker stays tripped before automatically resetting.

Conclusion

The LELB1-1REC4R-38661-70-V is a type of circuit breaker that is designed primarily for low voltage motor protection and over-load current protection. It features self-diagnostics, adjustable instantaneous trip current, adjustable short-time delay, and adjustable long-time delay. The working principle of the breaker is based on electromagnetism, and its adjustable features make it possible to customize it to suit a specific application. Ultimately, the LELB1-1REC4R-38661-70-V is a useful and versatile tool that can help protect devices and wiring from damage or destruction due to overloads or short-circuits.
