Siemens SENTRON Miniature Circuit Breaker 2-Pole 6A Type C 400V AC 72V DC 6kA DIN Rail IP20 5SY6206-7

The Siemens SENTRON 5SY6206-7 Miniature Circuit Breaker is purpose-built to provide dependable protection against overcurrents and short circuits in low-voltage installations, ensuring the safety of wiring and connected loads. Its 2-pole configuration allows it to simultaneously interrupt both phases, making it suitable for single-phase and multi-phase systems commonly found in commercial and industrial environments.

This breaker operates using Type C tripping characteristics, which means it can tolerate moderate inrush currents - ideal for circuits with inductive or mixed inductive-resistive loads such as motor starters, lighting circuits, and HVAC equipment. With a rated current of 6A, it is engineered to secure small branch circuits without nuisance tripping.

Supporting dual voltage operation, the breaker is rated for up to 400V AC and 72V DC, expanding its compatibility across a variety of electrical networks. The 6kA short-circuit capacity guarantees reliable blocking of even significant electrical faults, reducing the risk of fire or damage to critical equipment. It is designed for straightforward mounting on standard DIN rails, streamlining both new installations and retrofit upgrades.

Construction features include robust, halogen-free housing material that does not release toxic gases in the event of fire, enhancing its suitability for public buildings and safety-sensitive infrastructure projects. Screw terminal connections ensure consistent, vibration-resistant wire retention, minimizing the need for frequent maintenance and providing long service life.

The breaker incorporates an IP20 protection rating against solid foreign objects, safeguarding internals during everyday handling and operation. Its overall compact dimensions - 90mm in both height and depth and 76mm wide - make it suitable for crowded control cabinets or multi-circuit panels. With a weight of approximately 296g, it can be installed without imposing strain on DIN rail assemblies.

Siemens' SENTRON 5SY6 series breakers are widely adopted in industrial plants, commercial complexes, and public utilities for distribution board protection, lighting circuits, and electrical system upgrades. The modular design permits integration with accessories and auxiliary contacts from the SENTRON range, providing enhanced functionality as needed.

Typical applications include protecting lighting and socket outlets, HVAC controls, panelboards, machine instrumentation, and any sensitive electrical infrastructure requiring a fast-acting, durable, and standardized circuit protection solution.
