At 55 °C it's still 62 A, and at 65 °C it's 60 A, so the thermal margin is generous for a standard 63 A bus in a warm enclosure. Interrupting capacity is the headline number here: 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. The overcurrent release is a TM210 thermal-magnetic type — fixed thermal and magnetic settings, no electronic adjustment. No undervoltage release is fitted on this variant.
Dimensions & Panel Fit
Width of 101.6 mm (4 inches) is the standard 4-pole MCCB footprint for this current class; it occupies four 25 mm (1 inch) pole spaces on a DIN rail or panel-mount base. Height of 130 mm (5.12 inches) is compact enough for a 600 mm tall enclosure with two breaker rows.
Environmental & Compliance
Maximum power loss is 17.3 W — relevant for thermal calculations in a sealed enclosure with multiple breakers ganged together.
