Siemens SENTRON Miniature Circuit Breaker 4-Pole 63A Type B 400V AC 60V DC 10 kA Breaking Capacity 5SY4463-6

Siemens 5SY4463-6 SENTRON Miniature Circuit Breaker is a robust 4-pole automatic cut-out designed to protect electrical circuits by interrupting current flow during overload or short circuit events. Rated at 63 amperes with a Type B tripping curve, it is suitable for general-purpose protection in both industrial and residential installations.

Supporting an AC voltage of 400V and a DC voltage of 60V, this breaker exhibits a high breaking capacity of 10 kA, enabling it to safely handle fault currents without damage. The device mounts on DIN rails and features screw terminal connections for secure wiring.

Dimensionally compact, the breaker measures 90 mm in height, 76 mm in width, and 90 mm in depth, making it space-efficient for panel installations. The protective enclosure is rated IP20, providing adequate protection in standard electrical cabinets and enclosures.

Siemens Miniature Circuit Breakers meet stringent international standards including IEC/EN 60947-2 and IEC/EN 60898-1, ensuring quality and operational safety. Its toggle switch actuator allows for simple manual reset after tripping.

This model is part of Siemens SENTRON 5SY4 series, designed for extended product life and enhanced reliability, aligning with sustainability goals under Siemens Better World initiative. It can be combined with supplementary accessories such as fault signal contacts, shunt releases, under voltage releases, and remote operating mechanisms to tailor protection setups.

Typical applications include protection of electrical circuits, generators, long cable runs, and other installations requiring reliable trip characteristics compliant with Type B (trips between 3 to 5 times the rated current). This circuit breaker is an ideal choice for functional and residential construction sectors as well as various industrial automation systems.

Designed for industrial and residential electrical protection applications. Supports both AC voltage up to 400V and DC voltage up to 60V. Breaking capacity of 10 kA ensures safe interruption of short circuit currents. Mountable on DIN rail with screw-type terminals for secure connections.
