It is a 2-pole unit rated 16 A with a C tripping characteristic, breaking 10 kA at 440 V DC per IEC 60947-2. The same unit also handles 400 V AC at 10 kA, making it a universal-current breaker for mixed DC/AC panels.
DC ratings and polarity
The DC side is the headline: rated voltage 440 V DC, maximum operating voltage 500 V DC. The breaking capacity at DC per IEC 60947-2 is 10 kA. Polarity must be observed when wiring — this is not a polarity-agnostic AC/DC breaker; the supply cord position matters for DC arc extinction.
Width is 36 mm (2 modular units), depth 76 mm, height 90 mm, installation depth 70 mm. Fastening is via the quick-assembly system — snap-on DIN rail, any mounting position. Sealable for tamper-proof lockout.
Environmental range
Humidity derating: 95% RH at 55 °C, 55% RH at 70 °C, 35% RH at 75 °C. Pollution degree 3 — conductive pollution expected, so the breaker is suited for industrial or traction environments where dust and condensation are present.
