描述
1.保护功能
过载保护：
电子式脱扣器（P型）支持可调长延时（Ir）和短延时（Isd）保护，适应不同负载特性（如电机启动电流）。
典型应用：在工业电机控制中，通过设置Ir=1.2×电机额定电流，避免电机启动时误跳闸。
短路保护：
瞬时脱扣（Ii）可调，响应时间<10ms，快速切断短路电流，保护设备安全。
支持区域选择性联锁（ZSI），与上下游断路器协同动作，缩小停电范围。
接地故障保护（可选）：
部分型号支持剩余电流保护（RCD），检测接地故障电流（如30mA敏感型），防止触电事故。
2.智能控制与通信
远程操作：
支持电动操作机构（需选配），通过DCS/PLC或本地按钮实现远程分合闸，适用于无人值守场景。
典型应用：在数据中心配电系统中，远程控制断路器以隔离故障回路，减少人工干预风险。
通信接口：
可选配Modbus-RTU或Profibus-DP通信模块，实现与上位系统的数据交换（如电流、电压、故障记录）。
支持ABB Ability™EDCS能源管理平台，实时监控断路器状态，优化配电系统能效。
3.可靠性与安全性
高分断能力：
额定极限短路分断能力（Icu）可达100kA（415V），额定运行短路分断能力（Ics）为100%Icu，确保可靠切断故障电流。
典型应用：在石化行业配电系统中，承受短路电流冲击，避免断路器损坏导致事故扩大。
防护等级：
壳体防护等级IP40（防尘、防溅水），适用于室内一般工况；可选IP65（防尘、防水）型号用于户外或潮湿环境。
认证标准：
符合IEC 60947-2、GB 14048.2等国际/国内标准，通过CCC、CE、UL等认证，确保全球市场准入。
.1.Protection Functions
Overload Protection:
The electronic trip unit(P type)supports adjustable long-delay(Ir)and short-delay(Isd)protection to adapt to different load characteristics(such as motor starting current).
Typical Application:In industrial motor control,setting Ir=1.2×motor rated current prevents false tripping during motor startup.
Short-Circuit Protection:
The instantaneous trip(Ii)is adjustable,with a response time of<10ms,quickly interrupting short-circuit currents and protecting equipment.
Supports Zone Selective Interlocking(ZSI),coordinating with upstream and downstream circuit breakers to minimize power outages.
Ground Fault Protection(Optional):
Some models support residual current device(RCD)to detect ground fault current(such as the 30mA sensitive type)and prevent electric shock accidents.
2.Intelligent Control and Communication
Remote Operation:
Supports an optional motorized operating mechanism,enabling remote opening and closing of the circuit breaker via a DCS/PLC or local pushbuttons,making it suitable for unmanned operation.Typical Applications:Remotely controlling circuit breakers in data center power distribution systems to isolate faulty circuits and reduce the risk of manual intervention.
Communication Interface:
Optional Modbus-RTU or Profibus-DP communication modules enable data exchange with higher-level systems(such as current,voltage,and fault logs).
Support for the ABB Ability™EDCS energy management platform enables real-time monitoring of circuit breaker status and optimizes distribution system energy efficiency.
3.Reliability and Safety
High Breaking Capacity:
The rated ultimate short-circuit breaking capacity(Icu)reaches 100kA(415V)and the rated operating short-circuit breaking capacity(Ics)is 100%Icu,ensuring reliable interruption of fault currents.
Typical Applications:In petrochemical power distribution systems,short-circuit current surges are required to prevent circuit breaker damage and escalation of accidents.
Protection Rating:
The enclosure is IP40(dust and splash proof),suitable for general indoor use.An IP65(dust and splash proof)model is available for outdoor or humid environments.Certification Standards:
Compliant with international and domestic standards such as IEC 60947-2 and GB 14048.2,and certified by CCC,CE,and UL,ensuring global market access.
