Interrupting ratings across voltages
Interrupting capacity drops as system voltage rises: 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. For a 480 V panel, the 52.5 kA figure at 440 V is the closest published rating — you'd want to confirm the actual available fault current at the installation point doesn't exceed that.
Thermal derating and ambient limits
The breaker holds its full 160 A rating from 40 °C up through 50 °C. Above that it derates linearly: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Operating ambient range is -25 °C to +70 °C; storage range is -40 °C to +80 °C. Maximum power loss is 38 W — factor that into enclosure ventilation if the panel is densely packed.
Panel fit and mounting
Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep. That 70 mm depth (2.76 in) is the body only — allow extra for the shunt trip wiring and the auxiliary switch pigtails if you're routing through a tight gland plate. No communication function onboard; this is a standalone line-protection breaker, not a metering or networked unit.
