The shunt trip (STL) allows remote tripping from a PLC or emergency-stop circuit. Breaking capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 5.1 kA at 690 V. The 250 A rating holds from 40 °C through 50 °C ambient; above that, derate to 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C. Panel builders should account for the 48 W maximum power loss in enclosure thermal calculations.
No auxiliary contacts are included (auxiliary contact version: without), so if you need status feedback to a PLC, plan for a separate auxiliary switch block.
Trip unit and integrated functions
The ETU560 overcurrent release provides electronic protection with adjustable settings. Communication function is present (Communication Function: Yes), which means this breaker can integrate with a higher-level monitoring system — useful for power management or predictive maintenance setups. The voltage trigger (Voltage trigger: Yes) enables undervoltage or overvoltage tripping scenarios.
