The IP40 front protection suits indoor panel mounting where splash and dust ingress are controlled by the enclosure. At 415 V, this MCCB interrupts 440 kA — a rating that places it in the high-breaking-capacity tier of the SENTRON 3VA family. At 690 V, the breaking capacity drops to 187 kA, still sufficient for most 690 V motor-control-center feeds. The ETU850 electronic trip allows adjustable N-conductor protection (off, 40% to 160% of the phase setting), which is a practical feature for 4-wire distribution where neutral protection must be coordinated with phase protection. The 140 mm width occupies four 35 mm module spaces on a DIN rail, typical for a 4-pole MCCB. Bus-bar connection is via the front-access terminals; the ETU850 trip unit is field-replaceable without removing the breaker from the panel. The communication function (listed as present) allows integration with higher-level monitoring systems, though the specific protocol is not detailed in this listing.","metaTitle":"Siemens 3VA2140-0KP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 440 k","metaDescription":"Siemens SENTRON 3VA2140-0KP46-0AA0 molded case circuit breaker, 40 A continuous, 4-pole, ETU850 release, 440 kA breaking at 415 V.
