The TM210 release combines a thermal bimetal for overload protection and a magnetic coil for short-circuit response. The 40 A rating at 40 °C derates to 37 A at 60 °C and 36 A at 70 °C — a consideration for enclosed panels with limited airflow. The 2-pole form factor fits single-phase or two-leg three-phase circuits where a neutral is not switched. ## Interrupting capacity and selectivity planning At 480 VAC the 65 kA interrupting rating gives headroom for most industrial secondary-distribution panels. For 600Y/347 V systems the rating drops to 25 kA — still adequate for many lighting and small-power panels, but verify against the utility transformer size. These ratings let the breaker be used as a main or branch device without cascading upstream fuses in most standard installations. ## Panel integration — dimensions and mounting The 3VA4140-6ED24-0AA0 measures 50.8 mm wide, 129.4 mm tall, and 75.1 mm deep. The 2-inch width fits standard 2-pole MCCB panel slots. The SENTRON series carries UL file HEAB, confirming UL 489 listing for molded-case circuit breakers. The product designation matches the UL standard for branch-circuit protection. CE marking covers the European low-voltage directive. RoHS and REACH compliance documentation is available through the standard Siemens support channel — request it with the RFQ to keep your compliance file complete.","metaTitle":"Siemens 3VA4140-6ED24-0AA0 SENTRON MCCB, 40 A, 2-Pole, 100 k","metaDescription":"Siemens SENTRON 3VA4140-6ED24-0AA0 molded-case circuit breaker, 40 A continuous, 2-pole, TM210 release, 100 kA at 240 VAC.
