The DIII/E33/63A/EZN/1P fuse base is a single-pole fuse link holder designed for DIN 35 mm rail mounting inside distribution boards. It accepts DIII-size (E33 thread) cylindrical fuses up to 63 A and is rated for 500V AC. The M5 connection and included cover ensure secure termination and safe enclosure of the fuse element.

Its EZN type designation and DIII/E33 sizing are standard across European low-voltage protection equipment, making it straightforward to specify and source replacement fuses.
