If the panel ambient runs higher — say 50 °C — the breaker must be derated per the manufacturer's thermal curve; the TM-D trip unit is temperature-sensitive, so the thermal element responds to both load current and enclosure heat. The 4P (four-pole) configuration with neutral left is typical for three-phase plus neutral distribution in IEC panels. The Everlink lug terminals accept 2.5 to 95 mm² rigid aluminium or copper, or 2.5 to 70 mm² flexible copper — sized for the 16 A rating but also for the larger conductors a 70 kA fault duty sometimes requires. Mounts on a backplate in horizontal or vertical orientation; the 12-module 9 mm pitch width (108 mm) fits standard DIN-rail enclosure cutouts.
Deployment context
This breaker lives in a distribution panel — typically a sub-distribution board feeding lighting, small motor loads, or general-purpose sockets in a commercial or light industrial installation. The IP40 enclosure protection means it is suited for indoor panels where no water jets or dust ingress are expected; the IK07 impact rating handles accidental tool drops during maintenance.
