①
Select the Magnum breaker frame, then the current sensor and rating plug, and
finally the current limiter. Current limiters are mounted integral to the circuit breaker. Refer non-automatic MDSL breaker application requests to Eaton/Cutler-Hammer
➁
Refer to MDSL current limiter curves for let-through and time characteristics.
➂
The minimum selection provides for the lowest current let-through, but trip unit settings must be considered to avoid nuisance operation.
➃
The recommended selection avoids nuisance limiter operation and allows for system coordination within the trip unit settings while minimizing let-through.
➄
The maximum selection provides for maximum system coordination with let-through characteristics per the limiter selected.
➅
Heat sinks applied in conjunction with current limiters on this breaker rating.
