Description
Part of the legacy Multi9 C60N series, this 20A single-pole component delivers reliable current-limiting protection for industrial control panels. It installs onto standard 35mm DIN rail systems and serves as a predecessor to the newer M9F22120 model. Featuring a C-curve thermal-magnetic trip mechanism, it handles up to 10kA interrupting capacity at 240VAC. The padlockable design includes positive contact indication for enhanced safety during routine maintenance.Specifications

Product FAQs
6 answersCan the Square D MG24435 replace legacy Merlin Gerin breakers?
Yes, the MG24435 is a direct replacement for the older Merlin Gerin Multi9 C60N breaker with the exact same catalog number. Schneider Electric acquired Merlin Gerin and continues to manufacture this component under the Square D and Schneider Electric brands.
What is the magnetic trip curve for the MG24435 circuit breaker?
This breaker features a C-curve trip profile. The instantaneous magnetic trip is calibrated to operate between 7 and 10 times the continuous ampere rating, making it suitable for standard commercial and industrial loads.
Is the MG24435 rated as a UL 489 branch circuit breaker or a UL 1077 supplementary protector?
The MG24435 is a UL 1077 recognized supplementary protector. It is designed to provide additional protection within appliances or OEM equipment where branch circuit protection is already provided upstream.
What type of wire is compatible with the terminals on the MG24435?
The screw and clamp terminals are designed exclusively for copper (Cu) conductors, accepting wire sizes from 14 AWG up to 2 AWG.
Is the MG24435 suitable for direct current (DC) control circuits?
Yes, this 1-pole miniature circuit breaker is rated for DC applications up to 60VDC, providing a 10kA interrupting capacity for OEM control panels and automated machinery.
How does the MG24435 mount inside a control panel?
This miniature circuit breaker is designed to mount on a standard 35mm DIN rail. It is commonly used in DIN rail enclosures and OEM control panels.
