Product details

It carries a 20 A rated current at 40 °C (derated to 19 A at 60 °C) and a TM210 thermal-magnetic overcurrent release — the fixed thermal element handles overloads, the magnetic trip handles short-circuits.

This MCCB's interrupting rating varies with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.

The 3-pole footprint matches standard Siemens 3VA panel cutouts. The undervoltage release is factory-installed — no field wiring of a separate UVR module needed. No communication function or ground-fault monitoring on this variant.
