Publication No. 50 describes Arcolectric’s range of panel‑mounting fuse holders, offering body styles with D‑shaped or keyed mounting holes, and options for nut‑fixing or snap‑in installation with finger or tool release caps. Ordering references, panel cut‑out dimensions, and approval details (CSA, UL, IEC257) are listed for each type.
Technical data include a 16 A current rating, breakdown voltage over 4 kV DC, operating temperature from –55 °C to +70 °C, contact resistance of 5 mΩ (average), insulation resistance exceeding 100 MΩ, and UL 94 V2 flammability rating. The housings are molded from Nylon 66 (flame‑retardant), terminals are brass with silver plating, and contacts are copper alloy. Fixing torque is specified at 1.0 Nm (8.91 lb‑in) and humidity performance follows IEC 257 requirements.
