Product details

63 A MCCB with shunt trip — SENTRON 3VA1 line protection

It carries 63 A continuously at 40 °C (derated to 58 A at 70 °C), with a TM240 thermal-magnetic overcurrent release. Breaking capacity runs from 121 kA at 240 V down to 11.9 kA at 690 V — that 121 kA figure at 240 V covers high-fault utility feeds common in North American commercial and light industrial panels. At 415 V (typical European distribution) it still handles 75.6 kA, giving solid selectivity headroom downstream.

The 3VA1 frame measures 130 mm high × 76.2 mm wide × 70 mm deep. Width is 3 in. Maximum power dissipation is 17.3 W.

Comparison with 3VA1110-5ED36-0AC0

The 3VA1110-5ED36-0AC0 is a smaller-frame SENTRON MCCB with electronic release and no shunt trip. The 3VA1163-4EF32-0KA0 carries the shunt trip (STL) as standard. The 3VA1110 frame is physically larger.

Frequently asked questions

Will 3VA1163-4EF32-0KA0 drop into a panel designed for 3VA1110-5ED36-0AC0?

No. The 3VA1110 frame is physically larger (wider and deeper) and uses a different mounting footprint. The 3VA1163-4EF32-0KA0 is 76.2 mm wide × 70 mm deep; the 3VA1110 frame requires more space and a different cutout. Panel rework is needed.
