Description
A key objective for panel designers is safe distribution
of power to multiple fuse holders in a compact design.

most wire terminations in a timesaving package. A power
distribution block and associated conductors are no longer
needed to feed multiple POWR-SAFE fuse holders.

• Touch-safe design offers protection when replacing fuses
• Compact design
• 35 mm DIN Rail Mountable
• Available in one and three phase configurations
• No fuse pullers or tools required for fuse removal
• Can be cut down to optimal size
