Product details

SENTRON 3VA1220-6GF42-0KF0 — 200 A MCCB for Line Protection

Its breaking capacity reaches 220 kA at 240 V, 154 kA at 415 V, and 75.6 kA at 440 V — figures that govern fault-clearing capability at the point of common coupling.

Thermal Derating and Ambient Constraints

At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A.

The MCCB measures 70 mm deep, 140 mm wide, and 158 mm high. The 4-pole width (140 mm) matches the 4-pole slot in a Siemens distribution board; verify gland-plate clearance for the 70 mm depth before laying out the backplane.

Frequently asked questions

What is the breaking capacity of 3VA1220-6GF42-0KF0 at 415 V?
