Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the 690 V figure is the weak knee; verify the available fault current at your system voltage before specifying. ## Dimensions & Panel Fit The 3VA2025-5HL42-0AA0 measures 181 mm high, 140 mm wide, and 86 mm deep — a standard 4-pole MCCB footprint for DIN-rail or panel-mount enclosures. ## Thermal Performance & Ratings Insulation voltage is rated at 800 V, with an operating range of -25 °C to 70 °C and storage from -40 °C to 80 °C. Maximum power loss is 0.84 W — negligible for thermal budgeting inside a crowded panel.","metaTitle":"Siemens 3VA2025-5HL42-0AA0 SENTRON MCCB, 25 A, 4-Pole, ETU32","metaDescription":"Siemens 3VA2025-5HL42-0AA0 SENTRON molded case circuit breaker, 25 A continuous, 4-pole, ETU320 electronic trip unit.
