Front Connection of Secondary Circuits
All accessory terminals are located on a connecting block which is accessible from the front even
with the circuit breaker in the test or disconnected position. This is particularly useful for field
inspection and modification.

Advantages
Field-installable Accessories
n As the installation develops and changes, the circuit breaker can develop and change with it.
Most accessories are field-installable, without losing the UL Listing mark, without any adjustment
and with only the aid of a screwdriver.
n The uniform design of the circuit breaker line allows these accessories to be common for the
whole line.
