The 3VA2216-7MN32-0DA0: This MCCB delivers 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. Those figures mean it can sit upstream of smaller branch breakers in a high-fault panel and still achieve full selectivity — the 160 A frame clears a bolted fault without forcing the main breaker to trip.
Motor protection and release
The ETU350M electronic overcurrent release is purpose-built for motor protection — it provides adjustable thermal and magnetic curves plus phase failure detection, so a single-phase condition on a conveyor or pump motor trips the breaker before the winding overheats. The undervoltage release (UVR) drops the breaker when line voltage falls below a set threshold, which is standard for motor starters that need to prevent automatic restart after a dip.
Mechanical endurance and thermal derating
Rated for 20,000 mechanical operations — that is a solid service life for a 160 A frame in a motor control centre where the breaker cycles once or twice per shift. The thermal derating curve is tight: full 160 A up to 50 °C, then 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. In a hot enclosure or near a drive cabinet, that 144 A at 70 °C is the actual continuous rating you need to respect.
That 105 mm width is a standard 3-pole fixed-mount footprint for the 3VA2 series — it occupies the same panel cutout as other 160 A SENTRON frames, so a panel designed for a 3VA1112-5EF32-0CA0 will accept this breaker without drilling new holes or reworking busbars.
