400 A MCCB with 242 kA interrupting capacity — line protection for high-fault panels
Above 55 °C it derates linearly to 300 A at 70 °C (–). The interrupting capacity peaks at 242 kA at 240 V, dropping to 187 kA at 415/440 V, 121 kA at 500 V, and 7.5 kA at 690 V. Communication function is onboard, enabling remote monitoring or integration into a plant-wide power management system.
Thermal performance and power loss
Maximum power loss is 98.5 W at full rated current.
Adjustable trip unit — 80 A to 400 A
The trip unit is adjustable from 80 A minimum to 400 A full-scale. That range lets you fine-tune the breaker to the actual load without swapping the frame — useful when the same panel design is deployed across multiple sites with different feeder sizes. No trip indicator and no voltage trigger on this variant; the UVR handles the voltage-based trip function.
