Description
The CCMR series is ideal for space saving protection of
motors up to 40 hp*. It was designed specifically to withstand
sustained starting currents of small motors. The CCMR 60 fuse
is the smallest 60 A fuse available rated at
600 V. Compared to other UL L isted fuses, Class CC fuses are
the most current-limiting, rating for rating.
Applications
• Motor and motor branch circuit protection
Features/Benefits
• POWR-PRO Performance
• Extremely current-limiting
• Ratings up to 60 Amps
• 300 kA Interrupting Rating (self-certified)
