断路器的作用是切断和接通负荷电路，以及切断故障电路，防止事故扩大，保证安全运行。而高压断路器要开断1500V，电流为1500-2000A的电弧，这些电弧可拉长至2m仍然继续燃烧不熄灭。故灭弧是高压断路器**解决的问题。吹弧熄弧的原理主要是冷却电弧减弱热游离，另一方面通过吹弧拉长电弧加强带电粒子的复合和扩散，同时把弧隙中的带电粒子吹散，迅速***介质的绝缘强度。低压断路器也称为自动空气开关，可用来接通和分断负载电路，主电网失电保护继电器RMP-112D也可用来控制不频繁起动的电动机。它功能相当于闸刀开关、过电流继电器、失压继电器、热继电器及漏电保护器等电器部分或全部的功能总和，是低压配电网中一种重要的保护电器。DILM12-10C(220-230V50HZ)DILM12-10C(220V50/60HZ)DILM12-10C(220VDC)DILM12-10C(24V50/60HZ)DILM12-10C(24V50HZ)DILM12-10C(24VDC)DILM12-10C(380-400V50HZ)DILM12-21(230V50HZ,240V60HZ)DILM12-21(24VDC)DILM12-22(230V50HZ,240V60HZ)DILM12-22(24VDC)DILM12-32(230V50HZ,240V60HZ)DILM12-32(24VDC)DILM12-XDSB0/3DILM12-XDSB0/4DILM12-XDSB0/5DILM12-XEKDILM12-XEVDILM12-XMCEDILM12-XMCP/EDILM12-XMCP/TDILM12-XM***DILM12-XMVDILM12-XP1DILM12-XP2DILM12-XPBCDILM12-XRDILM12-XRA2DILM12-XRLDILM12-XS1DILM12-XSLDILM12-XSPDDILM12-XSPR240DILM12-XSPR48DILM12-XSPR500DILM12-XSPV130DILM12-XSPV240DILM12-XSPV48DILM12-XSPV500DILM12-XSPVL240DILM12-XSPVL48DILM15-01(*V50HZ)DILM15-01(*V60HZ)DILM15-01(*VDC)DILM15-01(110V50HZ,120V60HZ)DILM15-01(220V50/60HZ)DILM15-01(230V50/60HZ)DILM15-01(230V50HZ,240V60HZ)DILM15-01(240V50HZ)DILM15-01(24V50/60HZ)DILM15-01(24V50HZ)DILM15-01(24VDC)DILM15-01(TVC)DILM15-01(TVC200)DILM15-01C(110V50/60HZ)DILM15-01C(110V50HZ)DILM15-01C(110VDC)DILM15-01C(220-230V50HZ)DILM15-01C(220V50/60HZ)DILM15-01C(220VDC)DILM15-01C(24V50/60HZ)DILM15-01C(24V50HZ))
