Rated 50 A at 40 °C, it holds that current all the way to 50 °C before it starts to derate (49 A at 55 °C, 45 A at 70 °C). Breaking capacity hits 52.5 kA at 240 V and 32 kA at 415 V, which gives you solid headroom for high-fault commercial and industrial mains.
Width is 76.2 mm (3 in), depth 70 mm (2.76 in) — standard MCCB footprint for a 3-pole frame. Snaps onto DIN rail or bolts to a backplate; the 70 mm depth leaves room for busbar stacks and cable glands behind the panel door. Comes with an undervoltage release (UVR) integrated, so a loss of control voltage trips the breaker — good for emergency-stop chains where you want fail-safe isolation. The auxiliary switch block is a 2-switch HQ type, separate from the UVR coil.
