施耐德客服电话电动机启动负载类型施耐德的EASYPACT和MASTERPACT断路器的区别是什么？COMPACT首先两者均是低压断路器(1000V以下)先说Masterpact, 该系列是框架式断路器。

框架额定电流从800A----6300A不等。

Masterpact系列分M系列和MT系列。

M系列自1986年上市，2002年淘汰退市停产。

MT系列自2001年上市至今任然作为施耐德公司的主力框架断路器在产。

Easypact系列是塑壳式断路器，这里需要加入另一个系列Compact系列，Compact系列是施耐德公司的主力标准型塑壳式断路器。

Easypact系列是Compact系列的经济型产品。

举个例子，任何品牌的汽车都会有高配版、中配版、低配版。

那么Easypact系列就是低配版的。

Compact系列的壳架额定电流从100A----630A, 同样Easypact系列也是100A----630A的壳架额定电流。

施耐德NSX、NS塑壳断路器区别？NSX是NS停产后的代替产品。

原NS断路器壳架电流是从80~1600,80~630俗称小塑壳，绝大多数已停产，由NSX80~630代替；630b~1600为大塑壳，现在仍在生产。

NSX只有80~630的产品。

小塑壳NS由NSX代替后尺寸和安装尺寸完全相同，但断路器的门开孔的尺寸不一样。

总体来说，NSX可完全代替NS，且部分高级保护功能有所增强施耐德NS100 3P3t，4P3t 什么意思，NSX 的3P2D 3P3D 4P4D 4P3D、4P3D+N/2、OSN什么意思？Q “3P、4P”表示3极、4极断路器，“D”表示中性线的保护动作值。

Q 4D——中性线的保护动作值以Ir为基准；Q 3D+N/2——中性线的保护动作值以0.5Ir为基准；Q 3D——中性线无保护；Q 中性线过保护，保护值为各相保护电流值的1.6倍。

其中，NSX中的3P2D表示3极壳架（3P），其中2极具备保护（2D）；同理，3P3D表示3极壳架（3P），所有3极都具备保护（3D）；4P4D表示4极壳架（4P），所有4极都具备保护（相和中性线具备相同的保护阈值）同样，NS也是如此(要说明的是NSX是NS的升级版)“t”表示中性线的保护动作值。

In the event the trip unit trips the breaker on an overcurrent condition, or by an enhanced protection feature (if programmed, available on Digitrip 1150+ and PXR 25), the red trip flag releases and “pops” out toprovide local visual indication. This trip indication is always in addition to any LED trip indication provided by the trip unit.The remote reset trip indicator comes equipped with mechanical interlocking features. These features mechanically lock the breaker after it has tripped and prevent the breaker from being re-closed until the trip indicator has been reset.The remote reset trip indicator can be reset by applying a control voltage to the electromagnetic coil enclosed in the accessory device. After allowing sufficient time to reset the trip indicator, the control voltage is cutoff by a timing board also enclosed in the accessory device. The control voltage cannot, however, be continuously applied to the device to allow the board to reset and be ready for the next “event”. It is recommended that the control voltage not be applied to the secondary terminals any longer than 5 seconds.This product is intended for use in Magnum circuit breakers with PXR or Digitrip trip units.ote: N The proper control voltage of the device is marked on the accessory device.ote: N All images show a Magnum circuit breaker with a PXR trip unit unless stated otherwise.
