Accessory circuits exit the circuit breaker using one to three secondary disconnecting blocks (nine
wires each). Circuit breaker connection wires for the options installed with trip unit STR53UP exit
through the automatic secondary disconnecting blocks. These are made up of:
• A moving part connected to the circuit breaker through a support (one support per circuit breaker).
• A fixed part mounted on the plug-in base, equipped with connectors for wire up to 14 AWG (2.5 mm
2
).
For test purposes, circuit breakers may be equipped with one to three manual auxiliary connectors,
which allow the auxiliaries to remain connected when in the “disconnected” position.
The L-frame plug-in mounting is Listed under UL file E113555 and Certified under CSA file LR 69561.
