It carries a TM210 thermal-magnetic trip unit, rated 16 A continuously at ambient temperatures from 40 °C up to 55 °C, derating to 15 A at 60–70 °C. The 25.4 mm width (1 inch) lets it snap onto standard DIN rail alongside other SENTRON modular devices, saving panel space.
Rated interrupting capacity reaches 53 kA at 240 V AC and 8 kA at 415 V AC — the 240 V figure covers common North American panel feeds, while the 415 V rating suits European 400 V distribution. The maximum 320 A short-circuit current rating is the withstand capability of the breaker frame; the actual trip threshold is set by the 16 A TM210 unit. For DC applications the interrupting values are not listed here; refer to the 3VA MCCB manual for DC performance.
The breaker holds full 16 A rating from 40 °C to 55 °C without derating, then steps to 15 A at 60–70 °C. The IP40 front protection keeps dust and tools out of the terminal area but is not rated for washdown — keep it in a closed enclosure.
No official second-source cross-reference exists within the SENTRON family for this exact 1-pole 16 A TM210 variant.
