Siemens 3VA1032-2ED32-0HA0 — 32 A MCCB with 52.5 kA interrupting capacity
The Siemens SENTRON 3VA1032-2ED32-0HA0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A continuous current (Iu) at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated shunt trip (STL). Its interrupting capacity reaches 52.5 kA at 240 V and 32 kA at 415 V, making it suitable for high-fault distribution panels and motor branch circuits where selectivity and SCCR headroom are required.
Interrupting capacity and thermal derating
At 415 V the breaker clears 32 kA, dropping to 13.6 kA at 440 V and 7.5 kA at 690 V — the voltage-dependent curve typical of a compact MCCB frame. The 32 A rating holds flat from 40 °C through 50 °C; above that it derates to 30.72 A at 55 °C and 28.8 A at 70 °C. For a panel running at 60 °C ambient, budget 30.08 A continuous per pole.
The 3VA1032-2ED32-0HA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole footprint that fits standard Siemens SENTRON mounting plates and DIN-rail adapters.
