That's a fixed-setting thermal-magnetic replacement — no dials to spin, no modules to swap. Set it and forget it, which is exactly what you want when a line-down call comes in and the panel builder is already on site. That's a standard 3-pole MCCB envelope for a 40 A frame — it'll drop into most existing panel layouts without re-drilling the backplate or re-laying the bus bar. Power loss is only 1.2 W maximum — negligible for thermal budgeting inside a packed enclosure. ## What it doesn't do This is a straight line-protection breaker — no auxiliary gadgets. If you need those, you're looking at a different variant in the 3VA family. For a simple feeder or main breaker role, this keeps the wiring clean and the troubleshooting simple.","metaTitle":"Siemens 3VA2140-0HL32-0AA0 SENTRON MCCB, 40A, 3P, 690V","metaDescription":"Siemens SENTRON 3VA2140-0HL32-0AA0 molded case circuit breaker, 40 A continuous, 3-pole, 690 V AC, 440 kA at 415 V.
