1.适用范围与用途 Application Scope and Purpose
NDM3EU 系列产品是符合 UL489 相关内容认证的塑料外壳式断路器。该产品是我司针对北美市场需
求开发的符合 UL489 标准。该系列产品额定绝缘电压 AC800V，适用于交流 50/60Hz 配电系统，额定工作
电压至 AC600V，额定电流至 400A，用于过载和短路保护。具有过载长延时反时限，短路瞬时，短路短延
时保护功能，可以保护线路和电源设备免受损坏，产品符合 RoHS 标准。
具有隔离功能，其相应符号为： ;
同时符合标准：IEC60947-2、GB/T 14048.2、TUV
NDM3EU series products are Electronic Molded Case Circuit Breakers which are satisfied UL489.The
product is developed by our company for the North America market demand,and it meets the UL489 standard
molded case circuit breaker product.The rated insulation voltage of the product is 800VAC,which is suitabke for
AC power distribution system with 50Hz/60Hz,rated working voltage up to 600VAC,rated working current up to
400A for overload and short circuit protection.With overload long delay inverse time limit,short circuit
transient,short circuit short delay protection function,it can protect the line and power equipment from
damage.The product is RoHS compliant.
The circuit breaker has an isolating function with the corresponding symbol of ;
Also comply with standards: IEC60947-2, GB/T 14048.2 and certify by TUV Rheinland
