Product details

Siemens 3VA1120-5EE36-0AA0 — 20 A MCCB, 187 kA SCCR, Active Line

Rated 20 A continuously at 40 °C (derates to 19 A above 60 °C), this breaker carries a 187 kA interrupting capacity at 240 V AC — enough to clear high-fault utility feeds without cascading upstream.

Sourcing & Lifecycle — Active, Quoted to Order

The 3VA1120-5EE36-0AA0 is a current-catalog item with no announced last-time-buy. Compliance documentation (RoHS, REACH, IEC/UL ratings) is available from the manufacturer's support portal.

Peer Comparison — 3VA1110-5ED36-0AA0

The closest functional sibling is the 3VA1110-5ED36-0AA0, which shares the same 3-pole, TM220 trip, and 20 A frame but uses a lower interrupting rating (typically 100–150 kA at 240 V vs. 187 kA on this unit).

Frequently asked questions

Will 3VA1120-5EE36-0AA0 drop into a panel built for 3VA1110-5ED36-0AA0?

Yes — same 3-pole frame, same 76.2 mm width and 70 mm depth, same TM220 trip. The only difference is the higher interrupting rating on the 3VA1120-5EE36-0AA0, so it fits the same cutout and wiring without modification.
