The 86 mm depth, 105 mm width, and 181 mm height fit standard SENTRON panel cutouts; the footprint matches other 3VA frame sizes, so a panel laid out for a 3VA2116 accepts this 40 A unit without drilling new mounting holes. The trip indicator is present, and the breaker includes a trip-alarm switch that changes state on a fault event — useful for remote annunciation in an MCC or a PLC-driven safety circuit. The basic switch supplied is order code 3VA21405MN320AA0, which confirms the internal mechanism is a factory-matched assembly, not a field-replaceable module.","metaTitle":"Siemens SENTRON 3VA2140-5MN32-0CL0 MCCB, 40 A, 3-pole, 121 k","metaDescription":"Siemens SENTRON 3VA2140-5MN32-0CL0 molded case circuit breaker, 40 A, 3-pole, 121 kA at 415 V.
