Description
Part of the Multi9 C60 series, the Schneider Electric MG24144 delivers reliable short-circuit and overload protection for industrial control circuits. This 3-pole, 6A supplementary protector is designed to handle demanding electrical loads requiring a B-Curve trip profile. It installs easily onto standard 35mm DIN rails inside OEM panels and equipment enclosures. As a legacy component, it is replaced by the M9F21306. The unit provides a 10kA interrupting rating at 240VAC.Specifications

Product FAQs
7 answersIs the Schneider Electric MG24144 suitable for branch circuit protection?
No, the MG24144 is a UL 1077 recognized supplementary protector, not a UL 489 branch circuit breaker. It is designed to provide targeted short circuit and motor overload protection for specific equipment within a broader circuit.
What applications are best suited for the B-curve trip profile of the MG24144?
The B-curve thermal-magnetic trip characteristic, which trips instantaneously between 3.2 and 4.8 times the 6A rated current, is specifically designed for sensitive applications. It is ideal for protecting computers, electronic equipment, power supplies, and generators where low short-circuit fault currents are expected.
What type of DIN rail is required to mount the MG24144?
This supplementary protector mounts on a standard 35mm DIN rail. The modular Multi9 design allows it to easily snap into place within DIN rail enclosures and OEM panels.
What type of terminals are used on the MG24144, and what wire sizes do they accept?
It features pressure-plate style box lugs on both the line and load sides. These screw and clamp terminals are designed to accommodate multiple wires and accept gauges from 14 AWG up to 4 AWG.
Are field-installable accessories compatible with the MG24144?
Yes, this Multi9 C60 supplementary protector supports modular accessories. You can add an MX shunt trip or an MN undervoltage release for remote tripping capabilities. These accessories mount to the left side of the breaker.
How does the MG24144 indicate that it has tripped due to a fault?
A tripped supplementary protector is visually indicated by a red indicator flag on the front panel, allowing for quick identification of a fault in crowded OEM panels or DIN rail enclosures.
Can the MG24144 supplementary protector be reverse fed?
Yes, this Multi9 miniature circuit breaker is suitable for reverse feeding, providing flexibility for various wiring configurations in OEM panels.
