Product details

The TM240 overcurrent release is fixed (no adjustable thermal or magnetic settings), so what you see on the nameplate is what you get — no dials to mis-set on site. Breaking capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V.

Panel fit and auxiliary contacts

The breaker is 76.2 mm wide, 130 mm tall, and 70 mm deep — that's roughly 3 inches wide, so it fills three 18 mm pole spaces on a DIN rail or panel-mount plate. It ships with four HQ auxiliary switches (form C / changeover contacts) already installed — no add-on kit needed. That gives you status feedback for PLC inputs, alarm annunciation, or interlocking without cracking the cover.

Pricing and availability change weekly; we quote firm numbers against an RFQ. If you need a drop-in for a panel originally built around the 3VA1010-2ED32-0JA0, check the width — the 3VA1120 is 76.2 mm wide versus the 3VA1010's narrower frame, so it may not fit the same mounting hole pattern or bus bar spacing. Measure first.

Frequently asked questions

How do I get current pricing and availability for 3VA1120-5EF32-0AE0?

Submit an RFQ through the storefront. Availability and current pricing are confirmed at quote time — we don't publish live figures because the market moves daily.

Will 3VA1120-5EF32-0AE0 drop into a panel that was specified around 3VA1010-2ED32-0JA0 without rewiring?

Not without checking the mounting footprint. The 3VA1120 is 76.2 mm wide; the 3VA1010 uses a narrower frame, so the hole pattern and bus spacing may differ. Measure the existing cutout and compare before ordering.

What compliance documentation does this brand provide for 3VA1120-5EF32-0AE0?

Siemens typically provides RoHS, REACH, and UL/IEC declarations for the SENTRON 3VA series. Specific certificates for this order code are available on request with the RFQ.
