Product FAQs
5 answersIs the MG24474 still in active production, or is there a direct replacement?
The MG24474 is a legacy Multi 9 C60N series breaker. For modern upgrades, Schneider Electric has replaced this specific model with the Acti9 series part number M9F22363.
What trip curve does the MG24474 feature?
This breaker features a C-curve thermal magnetic trip characteristic. It is designed to trip instantaneously at 7 to 10 times the rated current, making it suitable for standard industrial loads and control wiring.
Can the MG24474 be used as a primary branch circuit breaker?
No. The MG24474 is a UL 1077 recognized supplementary protector. It is designed to provide additional protection for sensitive electronics inside equipment and must be used on the load side of a primary UL 489 branch circuit breaker or fuse.
Does the MG24474 support field-installable accessories?
Yes, this Multi 9 supplementary protector is compatible with standard C60N electrical auxiliaries, including shunt trips, auxiliary switches, alarm switches, and undervoltage releases.
Is the MG24474 a current-limiting breaker?
Yes, this breaker features a current-limiting design. In the event of a fault, it provides rapid electrical separation to minimize let-through energy and reduce potential damage to downstream components.
