Type A detection means it catches sinusoidal AC faults plus pulsating DC fault currents — the standard for mixed-load panels with electronics, drives, or rectifiers. The short-time delayed design (labeled 'short-time delayed' in the product designation) gives it selectivity against transient leakage, so nuisance trips from capacitive inrush or surge arrestors don't drop the whole submain. Mounts on DIN rail, takes 4 width units (72 mm), and installs in any orientation. Type A detection covers the fault signatures from single-phase rectified loads (switched-mode supplies, VFDs, UPS) that a plain AC type would miss. DIN rail mount, 72 mm wide (4 width units), 70 mm deep. IP20 with conductors connected — install inside a distribution board with a door or cover. Finger and back-of-hand safe terminals. Silicon-free construction suits potting or conformal-coat environments.","metaTitle":"Siemens 5SV3346-6LB01 SENTRON RCCB, 63 A, 30 mA, 4-pole, Typ","metaDescription":"Siemens 5SV3346-6LB01 SENTRON RCCB, 4-pole, Type A, short-time delayed, 63 A, 30 mA, 400 V AC.

The 5SV3346-6LB01 is a 4-pole RCCB (residual current protection, 63 A, 30 mA, Type A, short-time delayed). The 5SY4304-7CV is a 3-pole MCB (overcurrent protection only, 15 kA SCCR per IEC 60947-2, C-curve). They serve different functions in the panel — the RCCB provides earth leakage protection; the MCB provides short-circuit and overload protection. They are not drop-in substitutes."},{"question":"What compliance documentation does Siemens provide for 5SV3346-6LB01?","answer":"The product is silicon-free and carries IP20 protection with connected conductors. Standard Siemens SENTRON documentation includes the declaration of conformity to relevant EU directives (Low Voltage Directive, EMC Directive) and material declarations per RoHS and REACH. Specific certificates (UL, CSA, IEC) should be verified against the specific variant — the evidence does not list third-party approvals for this exact order code."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/5SV3346-6LB01","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/5SV3346-6LB01 when reusing this data.
