SIEMENS
High-performance 2-pole miniature circuit breaker designed for 400V AC applications. Featuring a 10A rated current and Type B tripping characteristic, it provides reliable short-circuit and overload protection with a 10kA breaking capacity and a compact 70mm mounting depth.
The Siemens 5SY4210-6 (SENTRON series) is a premier solution for protecting electrical circuits in residential, commercial, and industrial infrastructure. Built to rigorous international standards, this 2-pole MCB ensures maximum safety by preventing damage caused by overcurrents.
Its Type B characteristic is specifically engineered for circuit protection where switching surges are low, making it ideal for standard lighting and socket outlets. With a 10kA breaking capacity, it offers robust performance in the event of a high-fault current.
Enhanced Safety: Rapid disconnection during faults to protect personnel and equipment.
Space-Saving Design: Standardized 70mm depth allows for easy integration into shallow distribution boards.
Global Compliance: Meets IEC/EN standards, ensuring reliability across various international markets.
Easy Installation: Features ergonomic terminals for secure and fast wiring.
Type: B (standard) trip curve for typical residential and light commercial loads
Poles: 2-pole configuration
Rated Current: 10A
Rated Voltage: 400V AC
Breaking Capacity: 10 kA
Width: D=70 mm
Complies with IEC/EN 60898-1 standards
Ideal for overload and short circuit protection
