MAXIMUM OVERCURRENT PROTECTION AMPACITY
This rating specifies the proper overcurrent protection ampacity.
•OBDC breakers are
•Class T DC fuses are
•FXs used in home installations should use properly sized DC circuit breakers.
•A DC breaker includes both overcurrent protection and disconnect capability.
•OutBack Power Systems recommends Class T fuses for marine installations where a DC disconnect is not required.
