Rated 16 A continuous at 40 °C ambient, it holds that rating through 55 °C and derates to 15 A at 60 °C and above, so if your panel runs hot near the top of the enclosure, you lose 1 A of headroom. The interrupting capacity tells the real story: 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and still 17 kA at 690 V.
At 70 mm deep, 76.2 mm wide, and 130 mm tall, it fits a standard 3-pole MCCB footprint — no surprises when you're laying out a panel that already holds SENTRON breakers. The 3-pole form factor means it switches all three phases simultaneously; the UVR coil draws from the line side, so no auxiliary power supply is needed for the trip function.
