It carries a TM240 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element handles short-circuits — and delivers a breaking capacity of 75.6 kA at 240 V AC, 52.5 kA at 415 V, and 32 kA at 440 V, so it interrupts high-fault currents without cascading upstream.
The 25 A rating holds flat from 40 °C up to 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C. That means in a warm panel — say 55 °C ambient — you lose 1 A of headroom. Maximum power loss is 8.5 W, which matters for thermal coordination inside a sealed enclosure.
Panel fit
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into most DIN-rail or screw-mounted panel layouts.
