Lawson - House Service Cut-Out Fuse-Links 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.
