SENTRON 5SL is Siemens' miniature circuit breaker (MCB) for final circuits in the distribution boards of residential, commercial and infrastructure buildings. It protects cable and wiring against overload and short circuit and can also serve as a main switch to disconnect and isolate equipment. Siemens positions 5SL for basic applications and has optimized the 5SY and 5SP families for industrial circuits.
The core of the family differs only in breaking capacity and the characteristics offered: 5SL3 at 4.5 kA, 5SL6 at 6 kA and 5SL4 at 10 kA (to EN 60898-1). 5SL3 and 5SL6 come with characteristics B and C; 5SL4 adds D. Rated current is 0.3 A to 63 A in all three series, and dimensions and terminals are the same.
The characteristic (trip curve) sets the multiple of rated current (In) at which the magnetic release trips instantly: B at 3 to 5 × In, C at 5 to 10 × In and D at 10 to 20 × In. B suits socket and lighting circuits, C suits circuits with higher starting currents such as lamps and motors, and D suits pulse-generating equipment such as transformers and solenoid valves. The thermal release, per EN 60898-1, does not trip at 1.13 × In and trips within one hour at 1.45 × In.
Each series comes in six configurations: 1-pole (1 module = 18 mm), 1-pole+N and 2-pole (2 modules), 3-pole (3 modules), and 3-pole+N and 4-pole (4 modules). The 1-pole is rated 230/400 V, the 1-pole+N 230 V and the others 400 V.
Rated voltage 230/400 V AC at 50/60 Hz and degree of protection IP20 with connected conductors. Ambient temperature is -25 to +45 °C (5SL4 up to +55 °C). Each device is used either on AC or on DC (up to 62.5 V per pole), never mixed.
Auxiliary switches and fault signal contacts fit all three series; the 5SL4 also takes shunt trips, undervoltage releases and arc fault detection units (AFDD). The device is removed from the rail without tools.
The compact 1-pole+N version in one module (5SL30 and 5SL60, 2 A to 40 A, 3 to 6 kA depending on rated current) and the 5SL6 COM version with measuring and communication functions also exist. Their data differ from the tables above and must be read from the data sheet of the exact article.

The characteristic sets the multiple of rated current at which the magnetic release trips instantly: B at 3 to 5 times, C at 5 to 10 times and D at 10 to 20 times. Siemens recommends B for socket and lighting circuits, C for circuits with higher starting currents such as lamps and motors, and D for pulse-generating equipment such as transformers and solenoid valves. D exists only on 5SL4, and not every rated current is offered in all three characteristics.
Breaking capacity and the characteristics offered: 5SL3 at 4.5 kA and 5SL6 at 6 kA (both with B and C), and 5SL4 at 10 kA (with B, C and D). The 5SL4 accepts an ambient temperature up to +55 °C and, of the three, is the only series that takes shunt trips, undervoltage releases and AFDD. Rated current is 0.3 A to 63 A and the dimensions are the same in all three.
No. The 5SL trips on overload and short circuit only and gives no protection against leakage current to earth. For additional protection of people, combine it with a residual current operated circuit breaker (RCCB such as the 5SV) or use an RCBO.
For the standard devices (not the compact 5SL30 and 5SL60), taking 5SL6116-7: the digit after 5SL gives the series and breaking capacity (3 = 4.5, 6 = 6 and 4 = 10 kA); the next digit is the pole count (1 = 1-pole, 2 = 2-pole, 3 = 3-pole, 4 = 4-pole, 5 = 1-pole+N, 6 = 3-pole+N); the next two digits are the rated current (16 = 16 A; 14 = 0.3, 05 = 0.5, 01 = 1 and 15 = 1.6 A); and the digit after the dash is the characteristic (6 = B, 7 = C, 8 = D on 5SL4 only). So 5SL6116-7 is 6 kA, 1-pole, 16 A, characteristic C.
Only at low voltage: up to 62.5 V DC per pole, and each device is used either on AC only or on DC only; mixed use is not permitted. For higher DC voltages Siemens has the universal-current 5SY5 and 5SP5 families (EN 60898-2).
The 5SL is presented for basic building and infrastructure applications. Siemens has optimized the 5SY and 5SP families for industrial use; for an industrial circuit, compare the choice against the data sheets of those families as well.
