Breaking capacity varies sharply with system voltage: 121 kA at 240 V, 76 kA at 415 V, 53 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Current derating is minimal up to 50 °C — the breaker holds 100 A flat. At 55 °C it drops to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. Mechanical endurance is rated at 20,000 operations — typical for a fixed-mounted MCCB in a distribution board that sees infrequent switching. ## Panel integration and compliance Dimensions are 130 mm height, 101.6 mm width, 70 mm depth — a standard 4-pole SENTRON 3VA footprint that mounts on a DIN rail or directly to a backplate via the screw terminals. The N-conductor protection is set at 50% of the phase rating — standard for a 4-pole breaker in a TN or TT system where the neutral is not fully rated. The overcurrent release is a TM210 thermal-magnetic type, no electronic trip unit, no communication function.","metaTitle":"Siemens 3VA1110-4FD46-0AA0 SENTRON MCCB, 100 A, 4-Pole, Line","metaDescription":"Siemens 3VA1110-4FD46-0AA0 SENTRON molded case circuit breaker, 100 A rated, 4-pole, TM210 release.
