#1 Suitable for use in a circuit capable of delivering not more than I
480 Volts maximum, when protected by Class J time delay fuses with a maximum rating of Z
or by a circuit breaker with a maximum rating of Z2 as in this table.
#2 Correctly selected semiconductor fuses can provide additional protection against damage to the
SR55 unit (this is sometimes referred to as type 2 co-ordination). These semiconductor fuses are
recommended to provide this increased protection.
