Product details

The ETU560 electronic trip unit supports adjustable protection curves and communication, making this breaker suitable for selective coordination studies and power-monitoring schemes. The undervoltage release is integrated — it will trip on loss of control voltage, a common requirement for emergency-stop circuits and safety disconnects in conveyor or pump panels.

Above that it derates linearly: 24.06 A at 55 °C, 23.13 A at 60 °C, 22.19 A at 65 °C, and 21.25 A at 70 °C (–). In a sealed enclosure or next to heat-generating drives, that 70 °C ceiling is the real limit — not the 25 A label. The 140 mm width and 107 mm depth fit a standard 4-pole MCCB footprint; the IP40 front means the face is protected against tools and wires >1 mm but not against moisture, so mount it in a dry, lockable section of the panel.
