It is rated 500 A continuously at 40 °C, with the same rating holding through 50 °C before a gentle derate begins — 495 A at 55 °C, 490 A at 60 °C, 485 A at 65 °C, 480 A at 70 °C. Breaking capacity is 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 15.3 kA at 690 V. The short-time withstand (Icw) is 6 kA limited to 1 second — that figure governs selectivity with downstream breakers during a fault. For motor starting duty, the adjustable time-delay settings (minimum 4 s, maximum 13 s) let you ride through inrush without nuisance trips. No undervoltage release or communication module is fitted from the factory — those are add-on options if the application needs them.
Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C — cold-storage and freezer environments are within the operating envelope as long as the ambient stays above -25 °C. Maximum power loss is 99 W. That is the heat the breaker dissipates at full rated current — factor it into the enclosure thermal calculation, especially in a sealed NEMA 4X or IP65 cabinet where convection is limited.
