Type A detection handles pulsating DC fault currents from electronics (SMPS, LED drivers, EV chargers), so it's the right choice for circuits with downstream rectification. The 1-module width (roughly 18 mm per pole) keeps panel density tight — a 12-way board fits 12 of these RCBOs in a single row. Cable entry from bottom or top depending on busbar arrangement; the neutral terminal on the left side is common for Siemens RCBOs in this range. The 30 mA residual sensitivity meets the standard for socket-outlet and general-purpose circuit protection in most IEC 60364 installations.","metaTitle":"Siemens 5SU9353-7CR32 RCBO, 32 A, 30 mA, Type A, C-Char","metaDescription":"Siemens 5SU9353-7CR32 RCBO, 1P+N, 32 A, 30 mA, Type A, C-Char, 4.5 kA, 230 V AC.

This covers most domestic and light commercial distribution boards where the prospective short-circuit current is below that level. For industrial panels with higher fault capacity, you'd need a device rated 10 kA or higher."},{"question":"Where can I buy the 5SU9353-7CR32?","answer":"We source this part to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — send an RFQ and we'll get back with a firm price and lead time."},{"question":"What is the difference between Type A and Type AC for this RCBO?","answer":"Type A detects both sinusoidal AC fault currents and pulsating DC fault currents (rectified half-waves from electronics). Type AC only detects sinusoidal AC. The 5SU9353-7CR32 is Type A, so it's the correct choice for circuits with electronic loads like computers, LED drivers, or EV chargers."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SU9353-7CR32","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/5SU9353-7CR32 when reusing this data.
