塑殼斷路器CDM3-400N/4300B 400A
中文介紹
CDM3-400N/4300B 400A塑殼斷路器是德力西電氣推出的一款高性能電氣保護設(shè)備。該斷路器采用熱磁式脫扣器，具備可靠的過載和短路保護功能。其額定電流為400A，殼架等級額定電流為400A，極限短路分斷能力可達50kA，能夠滿足高負荷電路的保護需求。
在設(shè)計方面，CDM3-400N/4300B 400A斷路器具有良好的電氣性能和機械性能。其觸頭系統(tǒng)經(jīng)過優(yōu)化設(shè)計，確保在長期運行中保持穩(wěn)定的接觸電阻和低能耗。斷路器的操作機構(gòu)靈活可靠，支持手動操作，操作手柄設(shè)計合理，便于用戶快速進行分合閘操作。
此外，該斷路器還具備隔離功能，其隔離位置對應(yīng)于“OFF”位置，只有在觸頭真正打開時，操作手柄才能指示“OFF”位置。這種設(shè)計有效避免了誤操作帶來的安全隱患，確保了電路的安全性。
CDM3-400N/4300B 400A塑殼斷路器適用于多種應(yīng)用場景，包括工業(yè)設(shè)備、商業(yè)建筑、民用住宅以及基礎(chǔ)建設(shè)等。它能夠為電路提供穩(wěn)定的保護，防止因過載或短路導(dǎo)致的設(shè)備損壞和火災(zāi)風(fēng)險。其廣泛的應(yīng)用范圍和可靠的性能使其成為理想的電氣保護解決方案。
English Introduction
The CDM3-400N/4300B 400A molded case circuit breaker is a high-performance electrical protection device introduced by Delixi Electric. This circuit breaker is equipped with a thermal-magnetic trip unit, which provides reliable overload and short-circuit protection. With a rated current of 400A and a frame rating of 400A, it has an ultimate short-circuit breaking capacity of up to 50kA, making it suitable for high-load electrical circuits.
In terms of design, the CDM3-400N/4300B 400A circuit breaker features excellent electrical and mechanical properties. The contact system has been optimized to ensure stable contact resistance and low energy consumption during long-term operation. The operating mechanism of the circuit breaker is flexible and reliable, supporting manual operation. The well-designed operating handle allows users to quickly perform opening and closing operations.
Additionally, this circuit breaker has an isolation function. The isolation position corresponds to the “OFF” position, and the operating handle can only indicate the “OFF” position when the contacts are truly open. This design effectively prevents safety hazards caused by accidental operations and ensures the safety of the electrical circuit.
The CDM3-400N/4300B 400A molded case circuit breaker is suitable for a wide range of applications, including industrial equipment, commercial buildings, residential housing, and infrastructure projects. It provides stable protection for electrical circuits, preventing damage to equipment and fire risks caused by overload or short circuit. Its broad application scope and reliable performance make it an ideal solution for electrical protection.
