High DC voltage ratings for critical industrial or commercial
applications that have specific current limitation requirements.
10X better current limitation helps prevent equipment damage
caused by short-circuit events
200kA AC Interrupting ratings comply with NEC
®
Section 110.9
for today’s large capacity systems
20kA DC interrupting ratings help meet the needs of protecting
higher ampacity DC circuits
Incorporates Class R rejection feature. Can be inserted in non-
rejection type fuse holders to physically and electrically replace
fast-acting Class H, K1, K5, RK5, and other fast-acting fuses.

控制器局部网CAN(Controller Area Network)属于现场总线的一种，是一种有效支持分布式控制或实时控制的串行通信网络，被公认为是最有前途的现场总线之一。 在工业控制系统中，电动执行器是电动单元组合仪表中一个很重要的执行单元。它由控制电路和执行机构两个在电路上完全独立的部分组成，可接收来自调节器的电控信号，将其线性地转换成机械转角或直线位移，用来操纵风门、挡板、阀门等...[详细]
