Overcurrent and Surge Protection
Compaq Power Distribution Units include overcurrent and surge protection for both low and high
voltage equipment requirements and are equipped with a Circuit Breaker function to protect any
connected system devices from damage in the event of an incoming electrical surge or external
equipment malfunction.
Low Voltage Power Distribution Units feature two 15A circuit breakers, the 16A High Voltage
Model features two 10A circuit breakers with each circuit breaker protecting six receptacles. The
30A High Voltage PDU is equipped with four 10A output circuit breakers and four 20A input
slow blow fuses, with each protecting three output receptacles.
Figure 7. Compaq Power Distribution Unit’s Circuit Breaker
Compaq Power Distribution Units are equipped with a surge suppression feature that clamps
power when the maximum allowed voltage is reached. For maximum current ratings for Compaq
PDUs, please refer to Table 1.
