Description
Rated for 5kA at 480Y/277VAC, this two-pole miniature circuit breaker delivers B-curve protection for industrial control systems. Its current-limiting design ensures rapid fault clearing to minimize potential equipment damage. Installation is straightforward within standard DIN rail enclosures via screw clamp terminals. While succeeded by the M9F21216, it serves as an exact match for legacy setups. The unit incorporates a padlockable toggle and positive contact indication for enhanced safety.Specifications

Product FAQs
8 answersIs the Schneider Electric MG24133 still manufactured, or is there a replacement?
The MG24133 has been discontinued by Schneider Electric. The manufacturer's recommended replacement is the Multi9 M9F21216, which maintains the 2-pole, 16A, B-curve specifications for UL 1077 applications.
How is the MG24133 secured within an electrical enclosure?
It mounts directly onto a standard 35mm DIN rail, making it ideal for high-density OEM panels and industrial control systems.
What type of wire connections does the MG24133 use?
It utilizes screw clamp terminals that accept wire sizes from 14 AWG to 4 AWG, providing a secure connection for control panel wiring.
Can the MG24133 be used in DC voltage applications?
Yes, in addition to its AC ratings, this thermal-magnetic breaker is rated for up to 125VDC with a 10kA interrupting capacity, making it suitable for specific direct current control circuits.
Is the MG24133 rated as a primary branch circuit breaker?
No, the MG24133 is a UL 1077 recognized supplementary protector. It is designed to provide targeted overcurrent protection within appliances or equipment where primary branch circuit protection is already installed upstream.
How does the MG24133 protect maintenance personnel during equipment servicing?
The breaker includes a padlockable toggle that allows electricians to lock the device in the OFF position. It also features positive contact indication, showing a green mechanical indicator on the front face when all poles are safely open.
What does the B-curve designation on the MG24133 indicate?
The B-curve trip profile is designed for applications with low inrush currents, such as resistive loads or sensitive control circuitry. Its current-limiting design ensures rapid fault clearing to minimize potential equipment damage.
Does the MG24133 have a trip-free mechanism?
Yes, it features a trip-free mechanism. This ensures the internal contacts cannot be held in the ON position if a fault occurs, allowing the breaker to trip automatically regardless of external pressure on the toggle.
