The 690 V AC rated operating voltage covers 480 V and 600 V class systems, though the interrupting capacity drops to 25 kA at 480 V and 14 kA at 600 Y/347 V. Panel builders should note the 76.2 mm width (3 in) — it occupies a standard three-pole MCCB slot on the DIN rail or mounting plate, with 129.4 mm height and 75.1 mm depth leaving room for cable bending behind the breaker. ## Current derating across the panel ambient range The breaker is rated 90 A at 40 °C, but the TM210 release must be derated as the panel ambient climbs: 88 A at 45 °C, 86 A at 50 °C, 84 A at 55 °C, 81 A at 60 °C, 79 A at 65 °C, and 77 A at 70 °C. For a panel running at 50 °C — common in a non-air-conditioned electrical room — the usable continuous current is 86 A, not 90 A.","metaTitle":"Siemens 3VA4190-4ED34-0AA0 SENTRON MCCB, 90 A, 65 kA at 240","metaDescription":"Siemens SENTRON 3VA4190-4ED34-0AA0 molded-case circuit breaker, 3-pole, 90 A at 40 °C, 65 kA at 240 V.
