It carries a continuous current rating of 16 A across ambient temperatures up to 55 °C; at 60 °C it derates to 15 A, and holds that rating through 70 °C. The key decision for the buyer is the interrupting capacity: this unit delivers 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — high-fault ratings that suit it for main service-entrance or large distribution positions where available fault current is substantial.
The interrupting ratings tell the selectivity story. At 240 V the 220 kA figure is among the highest in the 3VA frame size — enough to sit upstream of a transformer or at the main lug of a high-capacity switchboard. The 154 kA at 415 V (common 400 V class) and 121 kA at 440 V cover most industrial distribution voltages. The sharp drop to 17 kA at 500 V and 690 V means this breaker is not the right choice for 690 V motor control centers or mining equipment; for those applications look to the 3VA2 frame or a current-limiting fuse combination. The TM210 trip unit provides fixed thermal and magnetic settings — no interchangeable rating plugs — so the 16 A continuous rating is hard-set at the factory.
At 101.6 mm wide (4 inches), it occupies a standard 4-pole MCCB footprint in a distribution panel.
