MDC DC Distribution Fuses are full-range fuses capable of safely interrupting currents ranging from 200% of nameplate current rating up to their maximum interrupting rating. MDC fuses can be used to protect the branch which includes the DC cabling and bus, along with any specific pieces of equipment.
DQS DC High-Speed fuses are intended for backup protection only, for specific pieces equipment such as but not limited to AC/DC inverters, converters, sensitive semiconductor components, etc. DQS fuses are designed to operate much faster and at higher current levels than MDC fuses while providing a lower clearing I2t.
