⚡ Key Features

16 A current rating with combined overload + short-circuit + earth-leakage protection in one device — complete circuit protection without a separate MCB and RCCB.
30 mA individual earth-leakage protection — an earth fault on this circuit trips only this RCBO; other circuits in the board remain energised, unlike a shared RCCB which disconnects all.
10 kA short-circuit breaking capacity — full fault protection at the point of load, matching the short-circuit demand of the installation.
1 Pole + Neutral (1P+N) — designed for single-phase final circuits with switched neutral — both live and neutral disconnect on trip for full isolation.
Single DIN rail module — same 17.5mm or 1P width as a standard MCB; maximises the number of protected circuits in a fixed enclosure size.
Manufactured to IEC 61009 / IS 12640-2 — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified, CE, cULus (select models) — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised Siemens product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: What load can the 5SU13546KK16 protect at its rated 16 A?

A: The 5SU13546KK16 is rated to carry and protect circuits up to 16 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 16 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 10 kA breaking capacity on the 5SU13546KK16 mean in practice?

A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the 5SU13546KK16 can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 10 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: Why is the 30 mA sensitivity specified on the 5SU13546KK16 and when should you choose a different rating?

A: 30 mA is the residual current at which the 5SU13546KK16 will trip within 300ms. A 30mA sensitivity provides additional shock protection (mandatory for socket circuits per IS 732). 100mA is used for fire protection (no shock protection). 300mA protects feeders without nuisance tripping. Choose based on the circuit’s risk profile — never use >30mA for socket outlet circuits in wet or high-risk locations.

Q: After a short-circuit trip on the 5SU13546KK16, can it be reset and reused immediately?

A: After a short-circuit trip, do not immediately reset the 5SU13546KK16. First, identify and clear the fault. Then inspect the device — if there is visible arc damage, melted insulation, or the handle does not reset smoothly, the device must be replaced. The 10 kA rated breaking capacity is not unlimited — it is the maximum fault current the device can interrupt safely for a defined number of operations (typically 1–3 at full Icu rating). After any significant fault, factor replacement into your maintenance budget.

Q: What is the difference between an RCBO and a standard MCB — and why use the 5SU13546KK16?

A: A standard MCB protects against overload and short-circuit only. An RCBO combines MCB overcurrent/short-circuit protection AND RCCB earth leakage detection in a single 1-module device — ideal where both forms of protection are needed in limited panel space. Choose the 5SU13546KK16 when the application specifically requires rcbo characteristics.
