Product details

What the 55 kA Icu means for your panel

The 3VA2063-5HM42-0AH0 is a 4-pole IEC frame 100 MCCB rated for a 63 A continuous current (In) with an ultimate breaking capacity (Icu) of 55 kA at 415 V AC. The ETU330 trip unit provides LSI (long-time, short-time, instantaneous) plus ground-fault (LIG) protection, with adjustable Ir from 25 A to 63 A and Ii from 1.5 to 12 times In. The ground-fault pickup (Ig) is adjustable between 0.25 and 1 times In, with a time delay of 0.1 or 0.3 seconds, making it suitable for selective coordination downstream.

The neutral conductor protection is adjustable (OFF or 100% of phase rating) via the trip unit settings, which is useful for 4-wire systems where neutral protection is required by local code. Spring-cage or screw terminals accept standard copper conductors up to the frame rating — verify lug range against your cable size during panel build.
