5SL6116-7 — Siemens 5SL Miniature Circuit Breaker
The Siemens 5SL miniature circuit breaker (MCB) is one of the most widely installed electrical protection devices in Saudi Arabia, providing reliable thermal-magnetic overcurrent and short-circuit protection for final distribution circuits in residential, commercial, and light industrial applications. The 5SL range covers rated currents from 0.5 A to 63 A in trip characteristics B, C, and D, with the 5SL6 variant offering an enhanced breaking capacity of 10 kA at 230/400 V — double the 6 kA of the standard 5SL4 — to address the higher prospective fault currents found in commercial and industrial distribution boards near transformer substations. Both variants are rated to IEC 60898-1 and comply with the Saudi Standards Authority (SASO) product approval requirements for electrical protection devices.
The 5SL's trip-free mechanism is its fundamental safety feature: the mechanism trips the breaker independently of the switch handle position, meaning that even if an operator holds the handle forcibly in the ON position during a short-circuit event, the contacts will still open. This positive safety behaviour prevents the most dangerous failure mode of inferior circuit breakers — contact welding during a sustained short circuit — and is the reason the 5SL is specified in safety-critical applications including hospital final circuits, data centre distribution boards, and industrial panel protection in Saudi Arabia's process facilities. The auxiliary contact and alarm contact accessories snap onto the side of the 5SL without tools, providing circuit open/close signalling for BMS integration and fault alarm outputs for remote monitoring in large commercial building installations.
In Saudi Arabia, the 5SL MCB is the standard branch circuit protection device for commercial towers in Riyadh and Jeddah's major real estate developments, residential villa compounds, industrial facilities in MODON zones across the Kingdom, and government building projects. SEC-approved panel builders routinely assemble consumer units and distribution boards using 5SL MCBs in combination with Siemens 5SV RCCBs, creating coordinated protection assemblies from a single manufacturer's product ecosystem. The 5SL's consistent DIN rail mounting and snap-on accessory system simplifies panel assembly and allows board modifications without rewiring when circuit changes are required during building fit-out.
Razz Middle East stocks 5SL MCBs in all current ratings from 1 A to 63 A, in B, C, and D trip characteristics, and in 1P, 1P+N, 2P, 3P, and 4P configurations for immediate delivery to panel builders and electrical contractors throughout Saudi Arabia.

Key Features & Benefits
- Trip-free mechanism opens the main contacts independently of handle position during a short-circuit event, preventing contact welding under sustained fault current — the critical safety feature that distinguishes the 5SL from inferior non-trip-free circuit breakers.
- 10 kA breaking capacity in the 5SL6 variant covers the prospective fault currents found in commercial and industrial distribution boards near transformer substations, satisfying the higher Icn requirements increasingly specified by Saudi project electrical engineers.
- B characteristic (3–5× In trip) for resistive and lightly inductive loads, C characteristic (5–10× In) for general motor and transformer circuits, and D characteristic (10–20× In) for high inrush loads cover all standard final circuit protection requirements from a single product family.
- Snap-on auxiliary contact (1NO+1NC) and alarm contact accessories mount without tools in under 30 seconds, providing circuit status signalling for BMS integration and fault alarm outputs for remote monitoring in large commercial building installations.
- Consistent DIN rail footprint with uniform 17.5 mm module width per pole allows precise panel space planning and enables board capacity modifications — adding or replacing breakers — without rewiring adjacent devices.
- 1P+N single-module format for single-phase circuits with neutral disconnection provides simultaneous phase and neutral protection in a single 17.5 mm width, doubling protection effectiveness versus phase-only MCBs for final circuits in Saudi residential and light commercial panels.
- Full product range from 0.5 A to 63 A in a single series covers all final circuit protection requirements from lighting (6–16 A) through socket outlets (16–32 A) to small motors and HVAC (40–63 A) without specifying different product families.
Industrial Applications in Saudi Arabia
- Residential villa and apartment consumer unit final circuit protection across Saudi Arabia's major housing developments, where 5SL MCBs in combination with 5SV RCCBs create coordinated protection assemblies from Siemens' consistent product ecosystem.
- Commercial office tower and retail centre distribution board branch circuit protection in Riyadh's King Abdullah Financial District and Jeddah's Corniche, where 5SL6 10 kA breaking capacity covers high fault levels near utility transformer substations.
- Industrial panel feeder and machine protection circuits in MODON industrial estates, where C and D characteristic 5SL MCBs handle transformer and motor circuit inrush currents without nuisance tripping during normal starting.
- Hospital final circuit protection in patient care areas and operating theatres, where the trip-free mechanism's positive safety behaviour under fault conditions satisfies Saudi Ministry of Health electrical installation requirements for healthcare facilities.
- Data centre and server room distribution board protection, where 5SL6 high breaking capacity combined with auxiliary contact monitoring provides both fault protection and remote circuit status visibility through the facility's DCIM system.
- Government building and institutional facility distribution boards under Vision 2030 infrastructure programmes, where SASO-approved 5SL MCBs satisfy Saudi standards compliance requirements for publicly-funded building electrical installations.
- Panel builder stock for MCC and LV switchboard assembly projects throughout the Kingdom, where 5SL MCBs serve as auxiliary and control circuit protection for PLC power supplies, instrument transformers, and control panel supplies.
