Product details

The 800 V rated insulation voltage and the breaking capacity profile — 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3 kA at 690 V — tell you this breaker is built for high-fault-capacity main or feeder duty, not branch-circuit light loads.

Sizing and thermal behaviour

Maximum power loss is 1.2 W, negligible for heat budgeting. The adjustable trip range spans 60 A minimum to 480 A maximum, so the ETU850 can be set to coordinate with downstream breakers or protect a specific load profile. The 3-pole construction suits three-phase systems; the lack of an undervoltage release or voltage trip means external monitoring or shunt-trip accessories would need to be added if those functions are required.

Frequently asked questions

How do I get current pricing and availability for 3VA2040-7KP36-0AA0?

Submit an RFQ against this part number. Pricing and availability are confirmed at quote time through independent distribution channels — no stock count or price figure is published here.

What is the breaking capacity of 3VA2040-7KP36-0AA0 at 240 V?

330 kA at 240 V. At 415 V and 440 V it's 242 kA, at 500 V it's 187 kA, and at 690 V it's 3 kA. The high 240 V figure suits it for 277/480 V wye main breakers where the line-to-ground fault current can be high.

Will 3VA2040-7KP36-0AA0 drop into a panel specified around 3VA2040-8HN42-0AA0 without rewiring?

Both are 3-pole SENTRON 3VA2 frame-size MCCBs with the same 105 mm width, 181 mm height, and 86 mm depth. The physical footprint and terminal layout are identical — it will mount on the same DIN rail or screw pattern and accept the same busbar connectors. The difference is the trip unit: this one uses the ETU850 electronic release versus the 8HN42 variant's release. No rewiring needed for the swap, but verify the trip settings match your coordination study.
