Circuit Breaker Capacity Requirements

Provide a separate circuit breaker for each PDU power cord connected to the server. These circuit breakers must accommodate the facility fault current ratings for the power infrastructure. Standard 3-pole circuit breakers are acceptable. The server has no specific time-to-trip requirements.

Contact your facilities manager or a qualified electrician to determine what type of circuit breakers accommodate your facility power infrastructure.

PDU Voltage Input
Circuit Breaker Capacity
200–220 VAC line-to-line (L-L) 3-pole
220/380–240/415 VAC line-to-line (L-L) 3-pole
20A (USA and Japan)
16A (Europe and the rest of the world)
