Circuit BreakersCircuit breakers are electrical devices that are used to protect circuits, whether they are residential, commercial or industrial, from overload and short circuit currents. The QLB-103-00DNN-3BA is a circuit breaker designed and manufactured by the QLB Group. It is a 3-pole reinforced trip AC circuit breaker designed to protect lighting, heating and other motor-driven circuits in non-residential buildings against overload and short circuit, as well as against earth faults. This article will explore the applications and working principles of the QLB-103-00DNN-3BA. Applications The QLB-103-00DNN-3BA is designed with a broad range of applications that make it the perfect choice for a variety of uses. It is ideal for use in commercial and industrial buildings, where it can be used to protect a lighting, heating or other motor-driven circuits from overload or short circuit. Additionally, it can also be used to protect against earth faults or ground faults. It is also suitable for use in one- or two-phase applications, as well as in three-phase systems. Furthermore, the QLB-103-00DNN-3BA is typically mounted in a panel box and is suitable for horizontal and vertical installation. Working Principle The QLB-103-00DNN-3BA is designed with three-pole tripping mechanism, which is the technology utilized in most circuit breakers. This tripping mechanism is triggered by a built-in thermal cut-out (TCO), which is sensitive to temperature and time. When the current within the circuit reaches a predetermined level, the TCO detects this and opens the circuit breaker. This prevents the circuit from being overloaded or suffering a short circuit, thus protecting the circuit and its components.In addition to the thermal cut-out, the QLB-103-00DNN-3BA also features an additional mechanical trip for improved protection. This additional trip can be triggered manually in the event of an overload or short circuit, or if the thermal cut-out has malfunctioned.Conclusion The QLB-103-00DNN-3BA is a 3-pole reinforced trip AC circuit breaker that is designed and manufactured by the QLB Group. It is used to protect a variety of circuits, including lighting, heating and motor-driven circuits, from overload and short circuit. It is suitable for one- and two-phase applications as well as three-phase systems and can be mounted in a panel box. It works by utilizing a three-pole tripping mechanism which is triggered by a built-in thermal cut-out. An additional mechanical trip is also included for improved protection. The QLB-103-00DNN-3BA is a great choice for commercial and industrial settings, providing reliable protection against electrical overloads and short circuits.
