It's a 3-pole, 3-protected-pole device rated for distribution duty, built to EN/IEC 60947-2, with suitability for isolation confirmed to that same standard.
The 50 A trip unit rating at 40 °C sets the continuous current limit for a distribution feeder or a large motor branch circuit. The TM-D trip provides thermal overload protection (L) and magnetic short-circuit protection (I) — no ground-fault element on board. Breaking capacity is the headline here: 85 kA Icu at 500 V AC, 80 kA at 525 V, and 75 kA at 690 V. The utilization category is A, so it's not intended for cascading selectivity with downstream breakers on the same pole; coordination needs to be checked upstream. Mechanical durability is 20,000 cycles; electrical durability varies by load: 20,000 cycles at 440 V at half rated current, 10,000 cycles at full 440 V In, and 5,000 cycles at 690 V In. That's a solid lifespan for a panel feeder that sees occasional switching, not a daily motor-start duty.
The 105 mm width and 161 mm height with an 86 mm depth mean it fits standard distribution panelboards. Connection pitch is 35 mm, and both line and load connections are front-accessed — no rear bus work needed. IP40 and IK07 keep it safe from tool drops and dust in a clean enclosure, but it's not for washdown zones.
