The adjustable trip class (10A, 10/10E, 20/20E, 30/30E) lets you match the overload curve to the motor start profile — a 10E setting for quick-start pumps, a 30E for high-inertia loads like centrifuges. The 86 mm depth, 105 mm width, and 181 mm height (–) fit the standard 3VA panel footprint; if you're swapping in a panel originally built around the 5SQ2370-2YA05 series, check the mounting hole pattern and bus-bar spacing — the 3VA uses a different lug arrangement and may require adapter brackets. Rated insulation voltage of 800 V covers 480Y/277 V and 600 V systems with headroom; the 1.6 W maximum power loss is low enough that adjacent breakers in a multi-unit lineup won't need forced-air cooling.","metaTitle":"Siemens 3VA2140-5MP32-0AA0 SENTRON MCCB, 40 A, 187 kA at 240","metaDescription":"Siemens 3VA2140-5MP32-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 187 kA at 240 V, motor protection design, adjustable trip class, current production.
