Its TM-D thermal-magnetic trip unit is rated 45 A at 40 °C and 45 A at 50 °C, so the full 45 A holds even in a warm enclosure — no derate needed at standard panel temperatures. The breaking capacity hits 25 kA Icu at 240 V AC and 10 kA at 440 V AC; that 10 kA at 440 V is the number to check if you are feeding a 400 V line with a high-fault utility transformer. Short-circuit protection and overload protection are built in.
Fixed-mount via backplate, with front-front wiring. Dimensions: 130 mm high, 75 mm wide, 60 mm deep. IP20 finger-safe terminals; IK07 impact rating for enclosures where tools or dropped parts are a risk. Toggle control with positive contact indication — you see the position, no guesswork.
Certified to EN/IEC 60947-1 and EN/IEC 60947-2, plus GB/T 14048.2 and JIS C8201-2-2. Pollution degree 3 — fine for most industrial control panels. No earth-leakage protection built in; add an external RCD if the circuit requires it.
