Overcurr ent Prote ction The Surge Protection Device (SPD ) draws very little current under normal conditions and will only conduct for a brief duration upon e ncountering a tr ansient s ur ge voltage. APC SPD ’ s contain UL Listed internal fusi ng to protect against abnormal voltage con ditions. Note: Only use fuses supplied by APC (see Replacem[...]

Parallel Connection When making a parallel type of connection (Figure 1), the length of the wiring to the Sur ge Protection Device (SPD) must be kept as sh ort as possible to substantiall y enhance the performance. Long wire ru ns are to be avoided if the unit is to perform as intended. T o reduce the impedance the wire dis plays to sur ge currents[...]
