Per the datasheet, the current rating holds at 32 A through 50 °C, then derates to 31 A at 55 °C and 60 °C, and to 30 A at 65 °C and 70 °C. That means in a warm panel — say 55 °C internal ambient — you lose 1 A of headroom per pole. The 32 A rating is the starting point; the thermal curve governs the real-world limit.
Interrupting capacity across voltages
Breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V distribution panel (common in North American industrial), the relevant figure is the 440 V rating at 32 kA — that is the closest published point. The 690 V rating at 11.9 kA covers European 400/690 V systems.
Auxiliary and release configuration
This variant ships with two auxiliary switches (HQ type) and an undervoltage release (UVR). The auxiliary switches provide status feedback — open/closed indication — for PLC or SCADA monitoring. No communication function or ground-fault monitoring on this order code.
Width at 76.2 mm (3 inches) is standard for a 3-pole MCCB in this class; it occupies three 25.4 mm module positions on a DIN rail if the mounting adapter is used.
