The TM240 overcurrent release gives a fixed thermal-magnetic trip curve.
The 63 A rating holds flat from 40 °C to 50 °C, then begins to derate: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
The breaker 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. No auxiliary contact is included; if you need a status feedback signal, order the auxiliary contact block separately. The undervoltage release is wired to a separate control circuit; verify the coil voltage matches your control supply before energizing.
