The 3VA1132-3EF32-0DH0: Breaking capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — that's serious fault-interruption headroom for a 32 A frame. The TM240 release gives thermal-magnetic protection with a fixed curve; no electronic adjustment, so it's a straightforward drop-in for standard distribution or motor branch circuits where you don't need programmable trip settings. It ships with an undervoltage release (UVR) and a 2-auxiliary + 1 trip-alarm switch configuration (HQ type). That's enough aux contacts for remote status and a separate alarm on trip — saves adding an external relay block for basic signaling.
Physical fit and panel integration
The 3VA1132-3EF32-0DH0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall. That 76.2 mm width is a standard 3-pole MCCB footprint — it fits existing SENTRON 3VA panel cutouts and busbar systems without re-drilling. The 70 mm depth leaves room in a 200 mm deep enclosure for wiring and bending radius behind the breaker. Front protection is IP40 — fine for a dry indoor panel, but keep it out of washdown zones. The trip indicator is visible through the cover, so a quick visual scan tells you which pole tripped without opening the door.
Thermal derating and ambient limits
Rated 32 A from 40 °C up to 50 °C ambient. At 55 °C it derates to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. If your panel runs hot — say near a drive stack or in a steel-mill control room — the derating curve is straightforward and published, no guesswork.
Sourcing and lifecycle
The lifecycle stage is listed as current — meaning Siemens still manufactures this order code. No phase-out notice, no last-time-buy clock. For volume or project-quantity needs, this part is quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
