Product details

This breaker delivers 330 kA interrupting capacity at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 7.5 kA at 690 V. Those figures are the ultimate short-circuit breaking capacity (Icu) for the respective voltages — high enough to serve as the main breaker in a panel with a large transformer feeding multiple downstream feeders.

Physical integration

Dimensions are 248 mm high, 184 mm wide, and 110 mm deep. The 4-pole footprint matches the standard SENTRON 3VA2 panel cutout; verify the mounting base and busbar spacing against your existing switchboard layout. The ETU350 trip unit is field-adjustable, and the neutral protection setting (OFF / 50% / 100%) is selected via DIP switches on the front.

Frequently asked questions

What is the breaking capacity of 3VA2325-7HN42-0AA0 at 415 V?

At 415 V AC the interrupting capacity is 242 kA. At 240 V it is 330 kA, and at 690 V it is 7.5 kA.

Where can I buy 3VA2325-7HN42-0AA0?
