Siemens Electronic Circuit Protective Device 2TE ECPD 1+N RCD Type F 30mA 16A

The Siemens 5TY1350-3MF16 is an electronic circuit protective device (ECPD) combining overcurrent and residual current protection in a compact 2TE design. It is specifically engineered for modern electrical installations requiring reliable protection against sinusoidal AC and pulsed DC residual currents, as well as high-frequency fault currents (Type F). This device is ideal for use in residential, commercial, and industrial applications where space-saving and high performance are essential.

Advantages

Combined overcurrent and residual current protection saves space and reduces installation time. Type F RCD ensures compatibility with frequency converters, LED lighting, and other electronic loads. High short-circuit withstand capability (10 kA) and surge current withstand (3 kA) provide robust protection. Screw terminals allow secure and easy wiring for conductors up to 25 mm².

Suitable for

• Residential and commercial distribution boards
• Circuits with frequency converters, UPS systems, or LED drivers
• Installations requiring Type F residual current protection
• DIN rail mounted systems in electrical cabinets
