Product details

What this MCCB carries in the carton

It's designed for line protection and includes onboard communication capability — no separate module needed for basic bus connectivity.

This breaker delivers 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V. Those are the maximum interrupting ratings at each voltage level — the actual available fault current at your panel's secondary must fall below these to maintain coordination.

No rewiring needed if you're swapping from a sibling with the same pole count and frame — the mounting footprint and terminal spacing are identical.

Trip unit and thermal performance

Maximum power loss is 7.7 W, which is modest for a 100 A frame and keeps internal cabinet heating manageable.

Frequently asked questions

Who supplies 3VA2010-8KP42-0AA0 and how is it quoted for volume purchases?

This part is sourced through independent distribution channels and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — submit an RFQ for volume or blanket pricing.

What is 3VA2010-8KP42-0AA0's listed depth?

The depth is 86 mm (3.39 in), with a width of 140 mm (5.51 in) and height of 181 mm (7.13 in).

Will 3VA2010-8KP42-0AA0 drop into a panel specified around 3VA2010-8HL42-0AA0 without rewiring?

Yes — both are 4-pole SENTRON 3VA frame breakers with the same mounting footprint and terminal layout. The swap is a straight mechanical and electrical drop-in as long as the trip unit settings and communication wiring are reconfigured for the ETU850.

What compliance documentation does Siemens provide for this MCCB?

Siemens SENTRON breakers carry UL, IEC, and CSA certifications as standard. RoHS and REACH declarations are available through the manufacturer's documentation portal. The IP40 front protection is per IEC 60529.
