Product FAQs
6 answersWhat type of enclosures are compatible with the MG24451 breaker?
This miniature circuit breaker is designed for standard 35mm DIN rail enclosures and OEM control panels. It easily snaps onto the rail and uses screw/clamp terminals for secure wiring connections.
Is the MG24451 suitable for both AC and DC control circuits?
Yes, this versatile thermal-magnetic breaker can protect both AC circuits (up to 480VAC) and DC circuits (up to 125VDC). This dual rating makes it ideal for mixed-voltage OEM panels and industrial control applications.
What is the modern replacement part number for the MG24451?
The MG24451 is a legacy Multi9 C60 series supplementary protector. Schneider Electric's direct modern equivalent in the updated Multi9 C60SP series is part number M9F22216.
How are wires terminated on the MG24451?
Conductors are secured using the breaker's built-in screw/clamp terminals. These lugs accommodate a wide range of wire sizes from 14 AWG up to 4 AWG, allowing for flexible integration into control panels.
Is the MG24451 considered a branch circuit breaker or a supplementary protector?
The MG24451 is a UL 1077 supplementary protector. It is designed to provide additional equipment-level protection inside OEM panels and appliances, rather than serving as a primary UL 489 branch circuit breaker.
What trip curve does the MG24451 feature?
The MG24451 features a C-Curve tripping characteristic. Its instantaneous trip function is designed to activate between 5 and 10 times the rated current, making it ideal for general-purpose loads and control circuits with moderate inrush currents.
