The C 40A curve handles motor-start and moderate inrush loads common in commercial distribution boards, while the 30 mA sensitivity covers basic shock protection for socket-outlet circuits. For pulsating DC or mixed-frequency faults (common with VFDs, LED drivers, or EV chargers) a Type A or Type F device would be needed instead. The 70 mm depth (D=70mm) is a standard modular dimension that fits flush in most Siemens and compatible distribution boards without protruding past the cover.","metaTitle":"Siemens 5SU9306-1DV40 LS/DI RCBO, 40A 30mA 6kA Type AC","metaDescription":"Siemens 5SU9306-1DV40 LS/DI protective device, Type AC, 40A C-curve, 30mA, 6kA, 1+N-pole.

Type AC (CO) means it detects sinusoidal AC fault currents only. D=70mm is the depth. IΔn 30mA is the rated residual operating current. 6kA is the short-circuit breaking capacity. 1+N-pole means it switches the live and neutral. C 40A is the overcurrent trip curve and rated current. 1MW is a reference to the maximum connected load at 230/400V."},{"question":"How do I get current pricing and availability for 5SU9306-1DV40?","answer":"Submit an RFQ — this part is sourced and quoted to order through independent distribution, with availability and current pricing confirmed at quote time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9306-1DV40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/5SU9306-1DV40 when reusing this data.
