What this MCCB does for a motor branch
It carries an ETU350M electronic overcurrent release with phase failure detection built in, so it handles the inrush and running protection of a 200 A motor branch without needing a separate relay.
Above that it steps down: 192 A at 55 °C, 188 A at 60 °C, 184 A at 65 °C, 180 A at 70 °C.
This MCCB's interrupting rating drops as voltage rises, which is typical for air-break designs. At 240 V it's 187 kA, at 415 V and 440 V it's 121 kA, at 500 V it's 75.6 kA, and at 690 V it's 17 kA. For a 400 V distribution panel the 121 kA figure gives solid headroom over typical 50-65 kA SCCR requirements. At 690 V the 17 kA limit means it's not a primary feeder breaker for high-fault 690 V systems — that's a coordination point to check.
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard 3-pole MCCB footprint for the 3VA2 frame size. No auxiliary contact version is fitted as standard, so if you need status feedback, that's an add-on. Maximum power loss is 75 W at rated load — account for that heat in a sealed enclosure.
