It is a single standard auxiliary contact that provides all the different indications remotely for ComPact NSX, ComPact NS, PowerPact Multistandard and EasyPact CVS circuit breakers. Remote status information are ON/OFF (OF), trip indication (SD) and fault-trip indication (SDE) for all circuit breakers types.

SDE（故障脱扣指示）：仅指示各种故障的保护动作脱扣，不含MX、MN的动作； SDV（Vigi故障指示）：仅反映Vigi模块的动作。

2012年11月15日 · SD：脱扣指示触点，指示断路器由于以下原因引起的脱扣：过载、短路、接地、漏电、MX、MN、按下脱扣测试按钮、插入式或抽出式安全脱扣装置引起的脱扣。 SDE：故障指示触点，指示断路器故障引起的脱扣：过载、短路、接地、漏电。 施耐德NS630：辅助触点OF、SD，SDE都代表什么意思？ OF：辅助触点，指示断路器的分合闸状态。 SD：脱扣指示触点，指示断路器由于以下原因引起的脱扣：过载、短路、接地、漏电、MX、MN、按下脱扣测试按钮 …

SD (trip indication) and SDE (fault-trip indication) are the indication contacts for compact NSX, but the function for trip are different. SD (trip indication) indicates that the circuit breaker has tripped due to: an overload; a short-circuit; an earth fault (Vigi) or a ground fault (Micrologic 6) operation of a voltage release

It is a single standard auxiliary contact that provides all the different indications remotely for ComPact NSX, ComPact NS, PowerPact Multistandard and EasyPact CVS circuit breakers. Remote status information are ON/OFF (OF), trip indication (SD) and fault-trip indication (SDE) for all circuit breakers types.

SD用来指示断路器脱扣状态，包括故障脱扣（如过载，短路，漏电等），以及非故障脱扣（如人为测试脱扣，MX分励、MN欠压脱扣等）。 SDE仅用来指示故障脱扣（如过载，短路，漏电等）。 将断路器先分闸，然后再合闸，按断路器上橙色的Trip按钮使断路器脱扣，手柄处于中间（脱扣）位置，将SDE/SD/OF安装与对应的槽内，需要注意：NSX100-250，TM, MA 或 Micrologic 2的脱扣单元，并且没有带电动操作机构的情况下，需要先装SDE适配器，然后再装SDE触 …

一般的理解是：sd是指示脱扣器的状态，只要脱扣就动作，包括欠压脱扣等；而sde只有在故障时才动作，像欠压脱扣不会动作。 在安装时，NSX SD装在左侧的插槽SDE装在右边的插槽

对于塑壳mccb： sde:故障保护脱扣. sd:sde+分励+失压. sdv:接地报警. 对于框架只有sde,包括了所有故障脱扣. 一般的理解是：sd是指示脱扣器的状态，只要脱扣就动作，包括欠压脱扣等；而sde只有在故障时才动作，像欠压脱扣不会动作。 在安装时，nsxsd装在左侧的插槽 ...

1. SDE (fault-trip indication) indicates that the circuit breaker has tripped due to: ·an overload ·a short-circuit ·an earth fault (Vigi) or a ground fault (MicroLogic 6). The SD contact returns to de-energised state when the circuit breaker is reset. SDV indicates that the circuit breaker has tripped due to an earth fault.

Schneider Electric 29452 It is a single low-level auxiliary contact that provides all the different indications remotely for Compact NSX, Compact NS, PowerPact Multistandard and EasyPact CVS circuit breakers. Remote status information are ON/OFF (OF), trip indication (SD) and fault-trip indication (SDE) for all circuit breakers... View More
