The Siemens SENTRON 5TY1350 is the world's first Electronic Circuit Protection Device (ECPD) that uses electronic switching based on advanced semiconductor technology. This innovative circuit breaker marks a new era in circuit protection, moving beyond traditional electromechanical switching to offer unprecedented speed, precision, and flexibility. As part of Siemens' SENTRON series, the 5TY1350 ECPD provides comprehensive protection against overload, short circuit, and fault currents in a single, compact device.

The 5TY1350 ECPD combines the functions of several conventional protection devices into one, replacing up to ten standard components. It integrates overload protection, short-circuit protection, and residual current protection (RCD Type F, 30 mA) with measurement and communication capabilities. By consolidating multiple protective functions, the ECPD reduces distribution board space by up to 80%, simplifies wiring, and cuts manufacturing materials by 1.53 kg per device, lowering carbon emissions by 50%.

Performance is where the 5TY1350 ECPD truly excels. It responds to current changes up to 1,000 times faster than comparable electromechanical circuit breakers, disconnecting within microseconds rather than milliseconds. This ultra-fast switching dramatically limits short-circuit energy, minimizing damage to downstream electrical equipment and ensuring maximum protection for sensitive electronics. The device achieves a short-circuit breaking capacity of 75 kA at 230 V AC, providing robust protection even in demanding industrial environments.

The 5TY1350 ECPD is highly parameterizable, allowing users to customize its behavior to meet specific application requirements. Using the SENTRON Powerconfig mobile app, engineers can adjust tripping characteristics, enable or disable additional functions, and monitor real-time operational data without opening the electrical cabinet. Communication capabilities support wireless connectivity for remote monitoring and configuration, streamlining maintenance and troubleshooting processes.

The 5TY1350 ECPD is available in multiple current ratings (6 A, 10 A, and 16 A) and is designed for 230 V AC single-phase systems with 1+N pole configuration in 2 MW (36 mm width) form factor. It mounts on standard DIN rails, supporting easy integration into new or existing distribution boards. The device meets IEC 60947-2 standards and carries CE certification, ensuring compliance with international safety regulations.

Key features include residual current monitoring (RCD Type F, 30 mA), which detects AC pulsating DC fault currents, making it suitable for circuits with frequency converters, LED lighting, and other electronics. The digital architecture enables seamless integration into smart power distribution systems, supporting energy monitoring and predictive maintenance applications. The 5TY1350 ECPD is also one of the first Siemens products to earn the Siemens EcoTech label, demonstrating commitment to environmentally low-impact solutions.

Typical applications for the 5TY1350 ECPD include industrial control cabinets, building automation, HVAC systems, pumping stations, conveyor systems, and any installation where reliable, space-efficient, and communication-capable circuit protection is required.
