ABL SURSUM D40 415V 3P is a three‑pole circuit breaker rated for 40 A (Inom) at 415 V AC, designed to protect three‑phase circuits from overcurrent and short circuits. It uses a type D characteristic with an ultimate breaking capacity of 20 kA at 415 V and carries IP20 ingress protection. The model is referenced as S303P‑D40 in ABB/Sursum line documentation, aligning with common protection devices for distribution boards and motor circuits that require a 40 A rating. This compact 3P breaker offers reliable isolation and overcurrent protection for 3‑phase loads in industrial or commercial electrical panels where 415 V systems are used.
