Siemens SENTRON 5SY6 Miniature Circuit Breaker, 1-Pole, 10A, Type C, 230V ac AC, 72 V dc DC, 6 kA Breaking Capacity

This miniature circuit breaker provides overcurrent protection for single-phase installations and incorporates a NEUTRAL pole switch. It is designed for DIN-rail mounting in distribution panels and offers thermal-magnetic tripping with a Type C characteristic for general-purpose protection in industrial and infrastructure settings. The device supports AC operation at 230V and limited DC operation up to 72V, and meets multiple international approvals for use in varied supply environments.

• 6kA breaking capacity provides safe fault interruption
• Type C tripping protects against moderate inrush currents
• Screw terminals allow secure conductor connections
• 10A rating supports common branch-circuit loads
• IP20 touch protection enables safer panel access

• Suitable for small industrial distribution boards
• Ideal for single-phase lighting and socket circuits
• Used with control panels requiring NEUTRAL switching
• Can be used for infrastructure and building installations

It accepts solid or stranded conductors from 0.75mm² up to 35mm² and finely stranded with ferrules up to 25mm².

Rated operational current is 10A at standard conditions and derates to about 9.39A at 40°C, 8.74A at 50°C and 8.4A at 55°C.

The breaker is specified for a typical mechanical service life of 10,000 operating cycles.

It may be mounted in any position and is secured on a DIN rail for panel installations.
