recloser vs fuses
(OP)
From a utility's standpoint, what are the advantages of having customers install a recloser vs a fuse as their main protective device?
We are required by the utility to install a recloser to protect our primary meter service and the added cost for installing a recloser as opposed to fuses is significantly higher.

1) sensitivity - you are close to end-of-line and the utility feeder breaker may not distinguish the load current and end-of-line fault current
2) selectivity - utility wants to minimize the outage and also implement the fuse saving strategy
3) controllability - utility may want to lock you out via SCADA under certain circumstances

A recloser can trip all three phases, if all three phases aren't trip it can cause problems at some locations.
A recloser can also have an earth fault element which can be set below full load current. Fuses need to be rated above the full load current.
