It carries 50 A continuously at 40 °C and delivers a 75.6 kA interrupting capacity at 240 VAC — enough to handle high-fault utility feeds or transformer secondaries in a distribution panel.
The 50 A rating holds steady from 40 °C through 50 °C, then derates to 49 A at 55 °C and 45 A at 70 °C — useful to know if the breaker sits near other heat sources in a crowded enclosure. The 75.6 kA at 240 V is the headline fault-clearing number; at 415 V it still breaks 52.5 kA, and at 690 V it holds 7.5 kA. The 3-pole construction fits standard three-phase feeders — motor branch circuits, lighting panels, or sub-feed distribution.
Built-in accessories and panel integration
The shunt trip allows remote tripping from a PLC or emergency-stop circuit; the auxiliary switches provide status feedback — open/closed indication to a control system or indicator lamp. No field-add-on kit needed for these functions. Dimensions are 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that fits SENTRON panelboards and most DIN-rail adapters.
