接触器凸耳和动态制动器1370凸耳套件规格和选择额定电机电枢电流（1）（1）额定电机电枢电压直接取自电机铭牌或电机数据。表中列出的电流（第1列）是电枢导体尺寸（第3列）和直流接触器额定值（第2列）允许的最大电流。直流接触器额定电枢导体尺寸（2）（2）电枢导体的尺寸根据NEC 430-22的规定，通过将额定电机电枢电流乘以1.25来确定。直流接线片额定值根据NEC表310-16确定，铜导体的绝缘温度为75°C（167°F），环境温度为30°C（86°F）。如果条件不同于NEC表310-16所示，则参考适用规范。DB导线尺寸（3）（3）动态制动（DB）导线的尺寸如注2所示，但由于这些导线中的电流持续时间较短，因此电流为半安培，其尺寸已满足NEMA标准ICS 3-302.62-动态制动的要求。如果负载惯性大于电机的惯性，则必须根据NEMA标准ICS 3.302.62进行计算，以确定正确的导线尺寸和DB电阻器瓦数。电枢导体压接凸耳孔尺寸DB导体压接突耳孔尺寸凸耳套件A DC A DC mm目录号2（AWG）mm2（自动化出版物1370-TD001C-EN-P-2013年12月直流回路接触器、接触器凸耳和动态制动器1370动态制动电阻器动态制动是一种可选的控制功能，有助于在故障条件下或响应滑行/DB停止时停止电机。动态制动不会提供保持制动功能，仅在电机旋转时有效。
Contactor Lugs and Dynamic Brakes 1370 Lug Kits Specifications and Selection Rated Motor Armature Current(1) (1) The Rated Motor Armature Current is taken directly from the motor nameplate or motor data. The current listed in the table (column 1) is the maximum current allowed for the Armature Conductor Size (column 3) and the DC Contactor Rating (column 2). DC Contactor Rating Armature Conductor Size(2) (2) The armature conductors are sized by multiplying the Rated Motor Armature Current by 1.25 as provided for in NEC 430-22. The DC lug ratings are determined from NEC Table 310-16 for copper conductors, insulation temperature rated at 75° C (167° F) at an ambient temperature of 30° C (86° F). If conditions are other than shown in NEC Table 310-16 then refer to applicable codes. DB Conductor Size(3) (3) The dynamic braking (DB) conductors are sized as in Note 2, but at half ampacily due to the short time duration of current flow in these conductors, and has been sized to satisfy NEMA Standard ICS 3-302.62 - Dynamic Braking. If the load inertia is larger than that of the motor, calculations must be made to determine correct conductor sizing and DB resistor wattage per NEMA Standard ICS 3.302.62.

Dynamic braking will not provide a holding brake function and is only effective when the motor is rotating.
