Product details

Breaking capacity — where it interrupts

This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3 kA at 690 V. The steep drop to 3 kA at 690 V means this is really a 480 V / 600 V class breaker; don't spec it for 690 V applications unless the fault current is well under 3 kA.

Mounting and environment

Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — standard SENTRON 3VA2 footprint for a 3-pole frame. Bolts into a panel or mounts on a mounting plate; no DIN rail on this frame size.

Frequently asked questions

Will 3VA2040-7HL32-0AA0 drop into a panel specified around 3VA2040-8HN42-0AA0 without rewiring?

Both are 3-pole SENTRON 3VA2 frame breakers with the same 105 mm width, 181 mm height, and 86 mm depth — same bolt pattern and bus-bar spacing, so mechanical fit is identical. The difference is the trip unit and rating; verify the 8HN42's continuous current and trip curve match your application before swapping.

What is 3VA2040-7HL32-0AA0's listed depth?

86 mm (3.39 in) from the mounting surface to the front of the breaker.
