How to Add Sub-Feed Output Distribution Circuit Breakers to the ATS

Circuit breaker adapter modules available from APC

Adapter modules are required when mounting breakers onto the panel bus in the ATS. Each adapter module can accommodate two breakers.

APC’s adapter modules are sized to fit all of the circuit breaker types described on the previous page: T1 single-pole breakers, T1 three-pole breakers, and T3 three-pole breakers. Two types of T1 single- pole adapters are offered: one that plugs into either L1 or L3, and one that plugs into L2. When adding single-pole breakers, try to keep the loads balanced among L1, L2, and L3.
