That thermal curve means in a warm panel you still get the full 125 A unless the ambient is pushing past 50 °C. The interrupting ratings are the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a site electrical engineer working selectivity, the 4-pole design means you can use it on a 3-phase + neutral system and coordinate with downstream breakers. Dimensions are 70 mm deep, 101.6 mm wide (4 inches), and 130 mm tall. The 4-inch width is standard for a 4-pole MCCB in this frame size — it'll drop into a panel that's laid out for a SENTRON 3VA footprint without surprises. ## What it doesn't have — so you don't order the wrong variant This is the bare-bones line-protection version. If you need any of those features — say, an undervoltage release for a safety circuit, or ground-fault alarm on a feeder — you need a different suffix on the 3VA order code. The TM210 release is the thermal-magnetic type, not electronic, so trip curve adjustment isn't available on this variant.","metaTitle":"Siemens 3VA1112-4ED46-0AA0 SENTRON MCCB, 125A 4-Pole, 121kA","metaDescription":"Siemens 3VA1112-4ED46-0AA0 SENTRON molded case circuit breaker, 125A continuous (40-50°C), 4-pole line protection, TM210 release, 121kA breaking at 240V.
