Siemens SENTRON 5SL6 Miniature Circuit Breaker, 2-Pole, 16A, Type C, 400V ac AC, 72 V dc DC, 6 kA Breaking Capacity

This miniature circuit breaker provides overcurrent protection for alternating-current installations and is intended for mounting on DIN-rail systems. It is a 2-pole device with Type C tripping behaviour, designed for electrical distribution in residential and infrastructure environments. The breaker is suitable for mixed AC and certain DC applications within the stated operational limits and is supplied with screw terminals for conductor connection.

• 6kA breaking capacity gives controlled fault interruption
• 16A rated current supports standard control-panel loads
• Type C tripping characteristic protects against moderate inrushes
• IP20 protection class ensures finger-safe live parts
• Halogen-free and silicon-free construction reduces contamination risk

• Suitable for protecting small distribution circuits in buildings
• Ideal for control panels requiring DIN-rail mounting
• Used for AC circuits up to 400V in infrastructure installations
• Suitable for battery-charging circuits with Peak DC considerations
• Used where sealable switching devices are required

It is rated for AC operation at 400V with a frequency of 50/60Hz and permits multi-phase operation up to 440V.

Solid, stranded and finely stranded conductors from 0.75mm² to 25mm² may be used with 2.5N·m to 3N·m Terminal torque.

The device accepts DC operation up to 62.5V per pole and accounts for battery-charging Peak voltages up to 72V.

It typically endures around 10 000 mechanical operating cycles.
