For a line protection role (not motor protection with adjustable overloads), this suits feeder circuits, distribution panels, and branch protection where the load current is stable and known. Interrupting capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. These are symmetrical RMS values. At 415 V — common in European industrial distribution — the 52.5 kA figure gives solid headroom for most panelboards with high-fault utility feeds. Thermal derating is published across the full ambient range: full 25 A from 40 °C through 50 °C, then 24 A at 55 °C and 60 °C, then 23 A at 65 °C and 70 °C. That means in a warm panel — say 55 °C inside the enclosure — the breaker is still good for 24 A continuous, which is 96 % of its nameplate. No forced derating needed until you cross 50 °C. The 4-pole width (101.6 mm) is roughly 4 inches — standard for a 4-pole MCCB in this frame size. Front protection is IP40, so it keeps tools and fingers out but is not sealed against moisture; mount inside a rated enclosure for wet or washdown areas.
The 4-pole construction with 100 % N-conductor protection means the neutral pole is fully rated and switches with the phases — no derating or separate neutral bar needed for solidly-grounded systems. The TM220 release has no external accessory slot for a shunt trip or undervoltage release without the optional motor drive extension (available as a field-fit accessory).
