The 1SNA115647R2300 is a grey, M4/8.D2.SFD double-deck screw clamp terminal block designed for protecting circuits with 5x20 and 5x25 fuses. This space-saving component features a fuse holder on the upper deck and a feed-through circuit on the lower deck. It is equipped with an integrated 24V AC/DC LED that provides a clear visual indication of a blown fuse, with a leakage current of less than 4.5 mA at 24V. The terminal block has an IEC rated voltage of 500V, a CSA rated voltage of 250V, and an impulse withstand voltage of 6000V. Its IP20 protection rating and quick fault identification make it suitable for industrial control panels and automation systems where reliability is critical.
