二、型号解析
SCE：ASCO自动转换开关的系列标识，代表标准型或经济型设计，适用于常规负载切换。
238：
2：表示两位置切换（主电源↔备用电源），无中间位置。
38：可能指开关的额定电流或框架代号（如38A或380A，需结合技术手册确认）。
D：表示三相四线制（3P+N）设计，支持三相负载和中性线切换。
009：
009：通常代表额定电流，即9A（但需注意：ASCO部分型号中此位数可能放大10倍，即90A，需以官方文档为准）。
另一种解释：若“238”为框架代号（如380A），则“009”可能为配置代码或版本号。
V0：
V：可能表示电压等级（如480V或600V，需确认），或指“Variable”（可调参数）。
0：通常为版本号或附加功能标识（如“0”表示基础版）。
注：根据ASCO常见型号规则，SCE238D009V0更可能为9A三相ATS，但需结合具体参数表确认。若负载电流较大，建议选择更高额定电流型号（如SCE300系列）。

ASCO SCE238D009V0 Product Details
I.Product Overview
The ASCO SCE238D009V0 is a three-phase automatic transfer switch(ATS)from ASCO Power Technologies(a brand of Emerson Electric specializing in critical power and automatic transfer switch solutions).This product,part of the SCE series,is designed for applications requiring high-reliability power supply,such as data centers,hospitals,and industrial facilities.It automatically switches to a backup power source in the event of a primary power failure,ensuring continuous operation of critical loads.
II.Model Explanation
SCE:ASCO’s series designation for automatic transfer switches,representing standard or economical designs suitable for general load switching.
238:
2:Indicates a two-position switch(primary power↔backup power),with no intermediate position.
38:May refer to the switch’s rated current or frame designation(e.g.,38A or 380A;please refer to the technical manual for confirmation).
D:Indicates a three-phase,four-wire(3P+N)design,supporting switching of three-phase loads and a neutral line.009:
009 usually represents the rated current,i.e.,9A(note:some ASCO models may have this digit inflated by 10,i.e.,90A;please refer to official documentation for accuracy).
Another explanation:If”238″is the frame code(e.g.,380A),”009″may be a configuration code or version number.
V0:
V:may indicate the voltage level(e.g.,480V or 600V,to be confirmed)or”Variable”(adjustable parameter).
0:Usually represents the version number or additional feature identifier(e.g.,”0″indicates the basic version).
Note:According to ASCO’s common model number conventions,the SCE238D009V0 is more likely a 9A three-phase ATS,but this should be confirmed with the specific datasheet.If the load current is high,it is recommended to select a model with a higher rated current(e.g.,the SCE300 series).
III.Core Parameters
Electrical Parameters:
Rated current:9A(or 90A,to be verified),supporting continuous load operation.Rated Voltage:
Three-Phase:Typically 480VAC(North American standard)or 400VAC(European/Asian standard).
Single-Phase:If single-phase applications are supported,the voltage range may be 120/240VAC.
Number of Poles****:3P+N(three-phase,four-wire),ensuring continuity of the neutral line during switching.
Frequency:50/60Hz(compatible with global power grids).
Switching Performance:
Switching Time:
Open Transition:Typical 100-500ms(primary power disconnected,backup power closed).
Closed Transition:Optional,provides zero-interruption switching(requires power synchronization).
Mechanical Life:≥10,000 operations(number of fault-free switching cycles).
Electrical Life:≥5,000 full-load switching cycles(depending on operating conditions).
Control and Protection:
Control Method:
Electric Operation:Switch contacts driven by an internal motor.Manual Operation:Manual switching is possible in emergencies(safety mechanism unlocked).
Protection Functions:
Overload Protection:Provided by a thermal relay or electronic trip unit.
Short-Circuit Protection:Requires an external circuit breaker(the ATS itself does not provide short-circuit breaking capability).
Undervoltage/Overvoltage Detection:Configurable thresholds trigger switching.
Phase Monitoring:Detects power phase sequence and loss to prevent accidental switching.
Environmental Adaptability:
Operating Temperature:-20°C to+60°C(Wide Temperature Design,Suitable for Harsh Environments).
Storage Temperature:-40°C to+85°C(Proof of Long-Term Storage).
Protection Rating:Typically IP20(Indoor Installation),optional IP54(Dust and Waterproof).
Altitude:≤2000 meters(Derating required for altitudes above 2000 meters).

Provides dual power supply redundancy for critical loads such as server cabinets and cooling systems.
Works with a generator or UPS to achieve seamless switching between mains power and backup power.
Medical Facilities:
Ensures power continuity in operating rooms,ICUs,and other areas,complying with NFPA 99 standards.
Industrial Automation:
Provides reliable power to PLCs,inverters,motors,and other equipment,preventing production interruptions.
