It carries a full-load current of 16 A at 40 °C ambient — no derating needed up to 55 °C, then 15 A at 60 °C and above. The TM240 thermal-magnetic release handles overloads and short-circuits without an external trip unit. Breaking capacity is the headline: 121 kA at 240 V AC, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Current lifecycle stage per the manufacturer — no phase-out or last-time-buy notice on record.
Four poles fit a standard MCCB cutout;
TM240 — a thermal-magnetic release with fixed thermal and magnetic settings, no electronic trip unit. Designed for line protection, not adjustable for selective coordination.
