APC PD3P100AT1B 100 A 3-Pole Breaker for Symmetra PX | PDU, APC

Keep critical power architecture protected at the branch level with this APC Schneider Electric 3-pole circuit breaker rated at 100 A. Designed for Symmetra PX250 and 500 kW-class deployments, it supports disciplined fault isolation in high-density UPS environments where selective protection is essential. In large data centers and enterprise electrical rooms, the breaker helps contain downstream faults without forcing broader shutdowns across the power path. This is the kind of component that earns its place in infrastructure built for continuity. A 3-pole design supports three-phase protection, while the T1 type specification aligns it with the intended Symmetra PX platform. For teams standardizing on APC power systems, it provides a direct-fit protection element that belongs in the same reliability tier as the equipment it serves. When the cost of interruption is measured in service impact, this breaker helps preserve the integrity of the distribution chain. It is a practical choice for installations that demand precise protection, platform compatibility, and the confidence that comes from using the right electrical component for the job.
