Product details

It carries a continuous current of 20 A at 40 °C through three poles, with an insulation voltage of 800 V — suitable for 480Y/277 V and 600 V delta systems where the breaker's voltage class exceeds the line-to-line potential.

The interrupting rating at 240 V is 220 kA, dropping to 154 kA at 415 V and 121 kA at 440 V.

Thermal performance and derating

The breaker holds 20 A continuously from 40 °C up to 55 °C. At 60 °C and 65 °C it derates to 19 A, and at 70 °C it stays at 19 A. The maximum power loss is 12 W.

Integrated accessories

The auxiliary switches are pre-installed; no field-assembly of add-on blocks is needed.
