Lawson NIT20M32 20 Amp BS88 32a Motor Rated HRC Fuse
Part No.:
The first rating is the continuous Current and the second is the Motor Starting Current
See motor rating chart below on product files
To avoid nuisance fuse-link operation due to overcurrent 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 relating to the operational characteristics. The letter ‘M’ separates these two ratings, for example, 20M32. This represents a fuse-link with a maximum continuous current rating of 20Amps, and an operational characteristic of 32 Amps rating to meet the motor starting current.
The range has a rated voltage of 415V a.c. and has been certified at a test recovery voltage of at least 110%. These fuselinks are therefore suitable for use on systems with voltages up to 457V a.c. The range also has a rating of 250V d. c.
