SENTRON 3VA2025-5HL32-0AH0 — 25 A MCCB with ETU320 release
The Siemens 3VA2025-5HL32-0AH0 is a 3-pole SENTRON molded case circuit breaker rated for 25 A continuous current, fitted with an ETU320 electronic trip unit. Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V — figures that govern selectivity coordination in a distribution panel.
The 25 A rating holds flat across the full ambient range from 40 °C to 70 °C — no derating needed in a warm enclosure. That is unusual for an MCCB and simplifies the panel thermal budget. Rated insulation voltage is 800 V, so it can be applied in 480/277 V and 600 V systems with margin. Dimensions are 105 mm wide × 181 mm high × 86 mm deep — a standard 3-pole MCCB footprint for panelboard or switchboard mounting.
