Communication function is onboard, though the protocol isn't specified in this listing — expect it to interface with a SENTRON communication module via the accessory slot.
Above that, derate linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C — the maximum operating temperature. Maximum power loss is 48 W, which factors into enclosure thermal calculations.
Breaking capacity by voltage
Breaking capacity varies significantly with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 6 kA at 690 V. The 690 V figure drops sharply — this MCCB is optimized for low-voltage distribution up to 500 V.
Environmental and storage limits
The storage maximum governs handling and warehousing, not running conditions. Trip indicator and voltage trigger are both present, aiding fault diagnosis without opening the panel.
