Its TM210 thermal-magnetic release handles overloads and short circuits without an external trip unit. At 415 V the interrupting rating drops to 52.5 kA, and at 690 V to 7.5 kA, so the voltage-dependent SCCR must be matched to the point of application.
Thermal derating and temperature range
The 32 A rating holds steady from 40 °C up to 50 °C, then begins a gradual derating: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
Shunt trip and auxiliary options
The auxiliary trip module order code is 3VA9688-0BL33.
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this 3-pole MCCB occupies a standard SENTRON footprint. It mounts via screw or busbar connection in a distribution board. The width of 76.2 mm (3 inches) is the same as other 3VA10xx frame sizes, so swapping between a 3VA1020 and this 3VA1032 does not require re-drilling the mounting plate — the busbar centers and DIN-rail adapter positions are identical across the frame.
