Product details

FI/LS-Protector Type A — 10 mA, 4.5 kA, 1+N B 16 A

The Siemens 5SU1153-6KV16 is a combined residual-current device and miniature circuit breaker (FI/LS-protector) in a single 1+N-pole module. Type A sensitivity (IΔn 10 mA) means it detects pulsating DC fault currents up to 6 mA superimposed on AC — essential on circuits feeding single-phase rectified loads like switching power supplies, LED drivers, or VFD auxiliary supplies.

DIN-rail mount (70 mm depth) in a standard 1+N module width. The neutral pole switches internally — no separate neutral bar needed downstream. Terminal capacity accepts 1.5–25 mm² copper; torque to 2.5 Nm. Verify the upstream protective device is coordinated within the 4.5 kA Icn limit — above that, a backup fuse or MCB is required per IEC 60898.

Frequently asked questions

What is 5SU1153-6KV16 used for?

It is a combined RCD/MCB (FI/LS-protector) Type A with 10 mA residual sensitivity and 4.5 kA short-circuit capacity, 1+N-pole B-curve 16 A. Typical applications include final circuits requiring both earth-leakage and overcurrent protection in a single module — common in residential, commercial, and light industrial sub-distribution boards.

Where can I buy 5SU1153-6KV16?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit a request for current pricing and availability; the quotation will confirm the supply posture at that time.
