This is a line-protection design intended for panelboard and distribution duty, not motor-circuit or generator protection. The interrupting ratings are what drive the specification here: 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V. At 500 V and 690 V it still holds 11.9 kA — meaning this breaker can be applied on a 690 V distribution bus with moderate fault current, not just the 480 V class. Thermal derating is minimal through 50 °C (still 40 A), then drops to 39 A at 55–60 °C and 38 A at 65 °C, with 37 A the floor at 70 °C. That means a panel at 50 °C ambient can hold the full 40 A nameplate without a derate factor — useful for a sealed or solar-direct enclosure. The TM210 trip unit is a fixed thermal-magnetic design with no interchangeable electronic trip or communication module. This keeps the BOM simple for a line-protection MCCB, but means no adjustable long-time or short-time pickup — the rating is fixed at 40 A. ## Panel Integration & Mounting Footprint is 76.2 mm wide (3 in), 130 mm tall, 70 mm deep — a standard 3-pole MCCB width that fits most Siemens 3VA panelboard and enclosure cutouts. Maximum power loss is 10.8 W. As a Siemens SENTRON MCCB, this breaker carries the usual IEC/EN 60947-2 certification. The evidence does not list specific UL/CSA file numbers, but the SENTRON 3VA series is typically dual-rated for IEC and UL markets — confirm the exact listing for your jurisdiction against the nameplate marking.","metaTitle":"Siemens SENTRON 3VA1140-4ED36-0AA0 MCCB, 40A 3-Pole, 121kA a","metaDescription":"Siemens SENTRON 3VA1140-4ED36-0AA0 molded case circuit breaker, 40A rated, 3-pole, TM210 thermal-magnetic trip, 121kA breaking at 240V.
