The ETU850 release allows fine-tuning of long-time, short-time, and instantaneous pickup for selective coordination. Dimensions are 181 mm height, 140 mm width, and 86 mm depth. The 140 mm width matches the standard 4-pole MCCB footprint in the SENTRON 3VA range, so it drops into an existing busbar or lug kit layout without panel rework. Depth of 86 mm leaves clearance behind a 200 mm deep enclosure for wiring and lug access.","metaTitle":"Siemens 3VA2140-5KP46-0AA0 SENTRON MCCB, 40 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2140-5KP46-0AA0 molded case circuit breaker. 40 A rated, 4-pole, line protection with ETU850 release. 187 kA interrupting at 240 V.
