Integrator note: 80 A MCCB with TM210 release
The TM210 designation indicates a fixed thermal pickup and a magnetic trip threshold set at 10× the rated current (800 A magnetic instantaneous), which governs short-circuit protection for line-feeder and distribution applications. Breaking capacity is specified across multiple voltage levels: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Thermal derating is published across a 40 °C to 70 °C ambient band: the breaker carries 160 A continuously at 40 °C, 45 °C, and 50 °C, then derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. For a panel enclosure running at 55 °C ambient, the effective continuous rating drops to 158 A — a factor to confirm against the connected load before committing the BOM line.
Physical footprint: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm / 4 in) is standard for a 4-pole MCCB in this frame size; verify the DIN-rail or mounting-plate spacing in the existing panel if replacing a different make.
Lifecycle and compliance posture
These omissions are by design for a basic thermal-magnetic feeder breaker — the absence of a trip indicator means fault-event diagnostics rely on external metering or a separate indication auxiliary.
