IP20 Fuse blocks for PSC range 3x, 7x & 000/00

Fusegear, for semiconductor fuse square body

Highlights:

IP20 Touch Safe
• SI Fuse holders for stud-type fuses, for
blade-type fuses

• SI 00 and SI 000 for bracket-type
fuses

• SI DIN 80 and DIN 110
Applications:

• Mounting in one-pole IP 20 fuseholder simplifies fuse usage outside convertisers for installations connected
with cables and bars.
• For TTF stud-type fuses
• For blade and bracket-type fuses as per DIN 43653 standard
sizes 000 - 00: 80 mm between axes
sizes 0 - 1 - 2 - 3: 80 and 110 mm between axes
• Suitable with or without microswitches installed on fuses.
• Fixation on rail or by screw.
