Havells LoadSafe range of enclosed switch disconnector fuses feature a compact design optimised for industrial applications requiring
an AC23A utilisation category rating. Primarily engineered for use with BS88 fuse links, the switches are supplied with isolator links fitted

is rigid and sized according to pole configuration with cable spreader boxes available for termination of larger cable sizes for ease of
installation.
