Schurter Single-Phase DIN Rail Power Line Filter 12A 240V AC 48V DC 50Hz/60Hz FPBB 3-103-712

Schurter 3-103-712 is a high-quality single-phase power line filter designed for DIN rail mounting, suitable for both AC and DC electrical systems operating at 240V AC and 48V DC respectively, with frequency compatibility of 50Hz and 60Hz. This filter is engineered to protect sensitive electrical and electronic equipment by significantly reducing electromagnetic interference (EMI) and noise from power lines.

The FPBB series features a two-stage construction for enhanced attenuation characteristics. Its slim profile with dimensions of 25mm length, 85mm height, and 89.5mm depth allows easy integration into electrical switch and control cabinets without occupying excessive space. The cage clamp terminal style facilitates fast and secure wiring, making installation efficient and safe.

Designed for industrial, commercial, laboratory, and manufacturing applications, this power line filter operates reliably within a temperature range from -40°C to 100°C. It supports a maximum continuous current of 12 amperes and maintains leakage current below 500 microamperes, improving overall system safety and noise suppression performance. With a power loss of only 1.6 watts, it ensures energy efficiency while meeting key international standards including IEC 61140, RoHS, UL, and VDE certifications.

The filter’s robust design incorporates overcurrent and surge protection features such as an integrated fuse holder and thermal circuit breaker, making it an ideal choice for effective interference voltage protection in electrical distribution systems.

Single-phase design for use in electrical switch and control cabinets. DIN rail mounting ensures secure installation and maintenance. Two-stage filtering provides very high attenuation of EMI. Cage clamp terminals allow quick, reliable wiring connection.

Compact dimensions facilitate space-saving integration into panels. Leakage current limited to 500μA enhances safety. Rated for 12A maximum current at 240V AC and 48V DC. Operating temperature range from -40°C to 100°C suits harsh industrial environments.

Power loss of 1.6W for efficient operation. Complies with IEC 61140, RoHS, UL, and VDE standards.
