Product details

Rated 80 A continuous at 40 °C and derated to 74 A at 70 °C, so the thermal curve is predictable across a warm enclosure; the TM210 overcurrent release handles the fixed thermal and magnetic trip settings. Breaking capacity sits at 121 kA at 240 V and 75.6 kA at 415 V — that's serious fault current handling for industrial mains, not just light commercial.

Thermal budget and environment

Max power loss is 19.2 W — that's the heat it dumps into the panel at full load, so factor that into your thermal calculation if the box is tight.

Frequently asked questions

What is the physical size of this breaker?

130 mm tall, 76.2 mm wide, 70 mm deep — a standard MCCB footprint for panel mounting.

Does this breaker have a trip indicator or undervoltage release?

No — it has no trip indicator, no undervoltage release, and no voltage-trip function; it's a straight thermal-magnetic line protection device.
