MOTOR CIRCUIT PROTECTION FUSE-LINKS 400/415 Volt Industrial Fuse-Links with Bo l ted Co n n e ctions to BS88: Part 2 • IEC60269-2 • EN60269-2 Rated voltage: 415V a.c. Breaking range and utilization category: gM Rated breaking capacity: 80kA at 415V a.c.

To avoid nuisance fuse-link ope ration due to ove rcurrent starting surges, fuse-links used in motor circuits often require higher ratings than the full load current of the motor. Motor circuit protection fuse-links have a dual current rating, consisting of a continuous current rating and a rating r elating to the operational characteristics. The letter ‘M’ separates these two ratings, for example, 32M50. This represents a fuse-link with a maximum co ntinuous curre nt rating of 32 Am p s, and an operational characteristic of 50 Amps rating to meet the motor starting current. The

table

be l ow shows

the

recommended fuse-links for various sizes of three phase 415V a.c. induction motors, where the run-up time is less than five seconds and the starting duty infrequent, ie; not more than twice per hour. For more arduous conditions the next higher rating should be used.

* Non-Standardized current rating additional to BS 88: Part 2 This data is based upon normal conditions and average efficiencies and power factors. Conditions such as long run-up times, large numbers of starts in succession, high ambient temperatures or abnormal transients during star/delta switching may necessitate adjustments to fuse-link selection.
