IS200TVIBH2BBB工控DCS系統備件
2.7（0.5）9.5（0.38）1370-LG280（1）額定電機電樞電流直接取自電機銘牌或電機數據。表中列出的電流（第1列）是電樞導體尺寸（第3列）和直流接觸器額定值（第2列）允許的最大電流。（2） 按照NEC 430-22（1987）的規定，電樞導體的尺寸通過將額定電機電樞電流乘以1.25來確定。直流接線片額定值根據NEC表310-16（1987）確定，銅導體的絕緣溫度額定值為75°C（167°F），環境溫度為30°C（86°F）。如果條件不同于NEC表310-16所示，則參考適用規范。（3） 動態制動（DB）導體的尺寸如注2所示， 2.7 (0.5) 9.5 (0.38) 1370-LG280 (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). (2) The armature conductors are sized by multiplying the Rated Motor Armature Current by 1.25 as provided for in NEC 430-22 (1987). The DC lug ratings are determined from NEC Table 310-16 (1987) 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. (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,
