LesPaul Posts: 467 Rating: (59)	hello, here some more informations: 3KL and 3KT devices are Switch Fuse Units (SFU) which serve as on-load isolators as well as short-circuit protection devices. These 3-pole SFUs are equipped with front-mounted holders for HRC fuses. In the OFF-position all fuse connections are isolated for safe maintenance.3KA devices are of the same basic construction design as 3KL and 3KT, but serve as on-load isolators only without short-circuit protection.No fuse holders are fitted to 3KA isolators. kind regards LesPaul
