3VA1150-6EF32-0JC0 — 50 A SENTRON MCCB with TM240 Release and Shunt Trip
Breaking capacity is the headline here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. No undervoltage release, no ground fault monitoring, and no communication function are fitted on this variant.
The 50 A rating holds flat from 40 °C through 50 °C ambient, then steps down: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. That 5 A drop from 50 °C to 70 °C is modest — the TM240 release runs cool enough that a panel hitting 60 °C ambient still delivers 47 A continuous.
The 3VA frame measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without oversizing the backpan. Front-face protection is IP40, so it's suitable for general-purpose indoor panels but not washdown environments. The 15,000-cycle mechanical endurance is typical for this class; expect it in a panel that sees occasional switching rather than daily motor-starting duty.
