SENTRON 3VA2140-8KP36-0AA0 — 40 A MCCB with ETU850 Trip Unit
The Siemens SENTRON 3VA2140-8KP36-0AA0 is a 3-pole molded case circuit breaker rated for 40 A continuous current, with an adjustable overcurrent release range from 60 A minimum to 480 A maximum — meaning the trip threshold can be dialed in across a wide band to match the actual load, not just the frame rating. Breaking capacity is rated at 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V — figures that cover most industrial service-entrance and sub-distribution fault levels without cascading upstream. The breaker includes a communication function onboard, enabling integration with higher-level monitoring or control systems — useful for remote trip indication and load management in automated lines.
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — the standard SENTRON 3VA2 frame footprint, so it retrofits into existing 3VA2 panel cutouts and bus-bar arrangements without re-drilling.
