It protects a 1+N-pole final circuit at 32 A, B-curve, with a 300 mA Type A residual-current trip. Type A detection means it catches pulsating DC fault currents from electronics or rectified loads — not just sinusoidal AC leakage. At 70 mm wide (4 module spaces) it fits a standard distribution board.","metaTitle":"5SU1654-6KV32 Siemens FI/LS Protector, Type A, 32A B, 300mA,","metaDescription":"Siemens 5SU1654-6KV32 FI/LS protector, Type A, 300mA, 10kA, 1+N-pole B 32A.

This covers fault currents from single-phase rectifiers, switched-mode power supplies, and electronic loads — common in modern final circuits with LED drivers, IT equipment, or appliance electronics."},{"question":"What is the breaking capacity and what standard does it meet?","answer":"Rated at 10 kA, which is the standard interrupting rating for domestic and light commercial distribution boards per IEC 61009-1. The B-curve (32 A) trips between 3 and 5 times rated current — suitable for resistive and general-purpose loads without high inrush."},{"question":"Where can I buy the 5SU1654-6KV32 and how is it quoted?","answer":"Sourced through independent distribution channels and quoted to order against an RFQ.
