What this MCCB delivers
Breaking capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3 kA at 690 V.
The 86 mm depth means it clears most shallow enclosure back-panels; verify your gland plate clearance if the breaker mounts near the rear wall.
Trip unit and protection capabilities
The ETU850 electronic trip unit supports communication and additional measurement functions — it can report load current and event data over the integrated communication interface, which is useful for energy monitoring or predictive maintenance schemes. Ground-fault monitoring is not built in; that requires an external module or a different variant. Front protection is IP40, suitable for indoor panel installation where no washdown or dust ingress is expected. Power dissipation at rated current is 13.5 W maximum — factor that into your enclosure thermal budget, especially in densely packed panels with multiple breakers.
