Product details

Integrator note — 3VA1120-3EF36-0HA0

Rated 20 A continuously at ambient temperatures from 40 °C through 55 °C, derating to 19 A at 60–70 °C — so in a warm panel near the top of the enclosure, plan for the 19 A ceiling rather than the 20 A nameplate. Breaking capacity is 75.6 kA at 240 VAC, 52.5 kA at 415 VAC, and 32 kA at 440 VAC — figures that govern fault-current withstand for the downstream distribution; at 500 V and 690 V it holds 11.9 kA.

Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in) — fits standard SENTRON 3VA mounting footprints; verify bus-bar and lug spacing against the existing panel layout before committing the BOM line.
