Product details

The Siemens 3VA2140-5MN32-0JH0 is a SENTRON 3VA2 series molded case circuit breaker (MCCB) rated for 40 A continuous current at 40 °C ambient, with a 3-pole configuration. It is designed specifically for motor protection, with phase failure detection built in.

Dimensions & Panel Fit

The 3VA2140-5MN32-0JH0 measures 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most SENTRON panelboards and switchgear cubicles without re-drilling the mounting plate.

Thermal & Environment

Maximum power dissipation is 1.6 W, low enough that ventilation slots in a standard enclosure are sufficient; no forced cooling required.
