It is a 3-pole unit rated 16 A at 40 °C, with a breaking capacity of 75.6 kA at 240 V AC — that rating drops to 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. It is a line-protection design — not a motor-protection or ground-fault version — so it is suited for feeder and subfeeder circuits where overcurrent and short-circuit protection is needed.
Thermal performance and derating
At 60 °C it derates to 15 A, and holds that figure through 70 °C. Maximum power loss is 13.1 W.
The 3-pole footprint is standard for SENTRON 3VA frame sizes in this current class.
