F U S E S

F U S E S

Lawson Type “ME” and “MF” fuse-links are for use in single or three-phase house service cut-outs or similar installations. The standardized BS 1361 breaking capacity of these fuse-links is 33kA at 0.3p. f. However to cater for increasing fault levels all Lawson house service cut-out fuse-links have been ASTA tested to 80kA at 0.15 p. f.

Lawson Type “MD” cylindrical fuse-links are for general purpose usage in three-phase sub-circuits. With a breaking capacity of 80kA, type “MD” fuse-links can be used to protect circuits with high fault levels such as industrial installations. The fuse-links also meet the performance requirements of BS88: Part 2 and IEC 60269-2 and have been independently ASTA Certified to the rules of the ASTA 20 Scheme.

F U S E S

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, 32M50. This represents a fuse-link with a maximum continuous current rating of 32 Am p s, and an operational characteristic of 50 Amps rating to meet the motor starting current.
