It carries a TM110M thermal-magnetic overcurrent release with a fixed magnetic trip threshold of 32 A (both minimum and maximum adjustable response value), meaning the instantaneous trip is locked at 32 A regardless of the continuous rating — a deliberate design for motor branch circuits where the magnetic pickup needs to ride through inrush. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Thermal performance and operating range
The 76.2 mm width is a standard 3-inch footprint for a 3-pole MCCB in this frame size — fits the typical DIN-rail or panel-mount cutout pattern used across the SENTRON 3VA family. The design accepts an optional motor drive (listed as a product extension), so remote electrical operation can be added without swapping the breaker.
