The overcurrent release is a TM210 thermal-magnetic type, adjustable for time-delay response up to 1 second at the tr max setting. Breaking capacity is 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — figures that cover most industrial distribution panels and motor control centers. Thermal derating is documented across the operating range: full 16 A up to 50 °C, then linearly down to 14.4 A at 70 °C.
The front face carries an IP40 protection rating, suitable for standard enclosure mounting with a gland plate or cover. The 3-pole footprint matches the SENTRON 3VA family panel cutout, so a panel originally specified for a similar 3VA frame can accept this unit without rewiring the bus bars or modifying the DIN-rail mounting base.
