Product details

FI/LS protector for a single-phase final circuit

The Siemens 5SU1654-6KV32 is a combined residual-current and miniature circuit breaker (RCBO) — one unit does what used to take two DIN-rail modules. 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.

Frequently asked questions

What does the Type A residual-current detection mean?

Type A detects sinusoidal AC residual currents and pulsating DC residual currents up to 6 mA DC superimposed. 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.

What is the breaking capacity and what standard does it meet?

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.

Where can I buy the 5SU1654-6KV32 and how is it quoted?

Sourced through independent distribution channels and quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — no stock counts or lead-time figures published here.
