Product details

SENTRON 3VA2125-8JQ36-0AA0 — 25 A MCCB with communication and ground-fault monitoring

It carries a 440 kA breaking capacity at 240 V, stepping down to 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — the full SCCR curve you need for selectivity studies against upstream gear. This MCCB includes a communication function and summation-current ground-fault monitoring on the L-conductor. No undervoltage release or trip indicator fitted on this variant. Maximum power loss is 0.5 W.

Standard SENTRON 3VA2 frame dimensions — drops into the same DIN-rail or screw-mount slot as other 3VA2 3-pole units. Verify busbar and lug kit compatibility with your existing panel layout.
