Product details

The Siemens 5SU1356-6KV13 is a combined residual-current device and miniature circuit breaker (RCBO) — an FI/LS protector — in a single 1+N-pole module. The 30 mA rated residual operating current (IΔn) provides personal protection against direct contact in TN and TT systems.

The B-curve trip characteristic (13 A rated current) means the magnetic release operates between 3 and 5 times In — so it clears short-circuits quickly but tolerates the inrush of resistive and moderate motor loads. The 6 kA breaking capacity (Icn) is the short-circuit withstand rating per EN 60898; it safely interrupts faults up to 6 kA without welding the contacts. The 1+N-pole form factor (switched phase, switched neutral) occupies a single modular DIN-rail width, so it replaces a separate MCB + RCD pair in the same panel space.

Frequently asked questions

Where can I buy 5SU1356-6KV13 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What is the closest alternative to 5SU1356-6KV13 in this component family?

Within the Siemens 5SU1 series, the closest alternative would be a variant with the same Type A, 30 mA, 6 kA, 1+N-pole construction but a different B-curve current rating (e.g., B 10A or B 16A) — the form factor and residual-current function are identical; only the overcurrent trip threshold changes. No pin-compatible drop-in with a different characteristic (C-curve) exists in the same housing.

What compliance documentation does Siemens provide for 5SU1356-6KV13?

Siemens typically provides a Declaration of Conformity (CE), RoHS and REACH compliance statements, and the product datasheet with EN 60898 / IEC 61008-1 test certificates. Specific document links are available on request with the RFQ.
