Trip Free
Will trip open on overload, even when forcibly held on. This
prevents the operator from damaging the circuit by holding
the handle in the ON position.
Trip Indication
The operating handle moves positively to the OFF position
on overload.

Environmental Specifications
Moisture and fungus resistance is provided by the use of
moisture resistant finishes. Special springs and treatment
for all ferrous parts eliminate inherent moisture-related
problems. The use of fungi inert cases and handles avoids
fungus-related problems.

Mounting Considerations
A three-inch spacing must be provided between the circuit
breaker and vent and any conductive surface. If closer than
three inches is necessary, then an insulator must be
installed on the conductive surface.
