Product details

At 60 °C it drops to 955 A, at 65 °C to 885 A, and at 70 °C to 815 A — the thermal curve matters if you are packing this breaker into a hot switchroom or a non-ventilated enclosure. The ETU860 electronic trip unit gives you adjustable long-time (tr 0.5–25 s), short-time (tsd 0.05–0.5 s), and ground-fault protection with summation-current sensing on L+N. N-conductor protection is adjustable OFF, 50%, or 100%.

Integration notes for the panel builder

The 280 mm width means it occupies roughly 11 inches of rail space — plan gland-plate entry and cable bending radius accordingly.
