Product FAQs
7 answersIs the Square D MG24468 still in production, or is there a direct replacement?
The MG24468 has been discontinued by Schneider Electric. The manufacturer's recommended direct replacement is catalog number M9F22316, which shares the same 16A, 3-pole, C-curve specifications and physical dimensions.
What is the trip curve characteristic for the MG24468 miniature circuit breaker?
This breaker features a C-curve trip characteristic. It is designed to trip between 5 and 10 times the 16A rated current, making it suitable for loads with moderate inrush currents like small motors and control circuits.
Is the MG24468 rated as a branch circuit breaker or a supplementary protector?
It is a UL 1077 recognized supplementary protector. It is intended for use within equipment or control panels where branch circuit protection is already provided or not required, and cannot be used as a standalone UL 489 branch circuit breaker.
What are the physical dimensions of the MG24468 breaker?
The breaker measures 2.14 inches wide (54mm), 3.19 inches high (81mm), and 3.00 inches deep (76mm). It occupies three standard 18mm modules on a 35mm DIN rail.
How does the MG24468 mount inside a control panel?
It snaps directly onto a standard 35mm DIN rail. While some legacy descriptions may refer to it as a bolt-on breaker, the C60N series utilizes a standard DIN rail mounting clip for installation in OEM control panels and enclosures.
Can the MG24468 be reverse fed?
Yes, this supplementary protector is suitable for reverse feed applications. You can wire the line and load connections to either the top or bottom terminals without compromising the thermal-magnetic trip mechanism.
Is the MG24468 compatible with Multi9 series accessories?
Yes, as part of the Multi9 and Acti9 family, it accepts standard field-installable accessories such as auxiliary contacts, shunt trips, and undervoltage releases designed for the C60N series.
