It is a 3-pole unit rated at 25 A continuous current (Iu) and carries a TM240 thermal-magnetic release, so the thermal pickup tracks the cable temperature and the magnetic trip is fixed at 240 A for instantaneous short-circuit clearing. The interrupting ratings are the headline here: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Thermal derating is published: full 25 A up to 50 °C, then 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C.
Panel integration and auxiliary options
The 3VA1125-5EF32-0KC0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts. The integrated auxiliary trip order code is 3VA9688-0BL33 if you need a spare or replacement.
