Description
Designed for commercial applications, the Schneider Electric 24449 offers robust thermal-magnetic protection. This 2-pole, 10A breaker is part of the Multi 9 C60 series. It mounts securely onto standard DIN rails, making it ideal for Multi 9 modular enclosures. As a legacy component, it provides an exact fit for existing panels and is superseded by the M9F22210. Equipped with a C-curve trip characteristic, it accommodates moderate inrush currents while delivering a 5kAIC rating at 480Y/277VAC.Specifications

Product FAQs
6 answersWhat is the modern replacement for the Merlin Gerin 24449 circuit breaker?
Schneider Electric has superseded the legacy 24449 with part number M9F22210. The M9F22210 is part of the updated Multi 9 C60SP series and maintains the same 10A, 2-pole, C-curve specifications for DIN rail mounting.
What is the trip curve characteristic of the 24449 miniature circuit breaker?
This breaker features a C-curve trip profile. It is engineered to trip instantaneously at 5 to 10 times its 10A rated current, making it suitable for commercial and industrial loads with moderate inrush currents.
Is the Schneider Electric 24449 rated as a UL 489 branch circuit breaker?
No, the 24449 is a UL 1077 recognized supplementary protector. It is intended to provide localized protection within equipment or control panels where upstream branch circuit protection is already installed.
What type of mounting rail is required for the 24449 circuit breaker?
This Multi 9 series breaker is designed to snap directly onto a standard 35mm symmetrical DIN rail. It is compatible with DIN rail panels and Multi 9 modular enclosures.
How does the thermal-magnetic trip mechanism function on the 24449 breaker?
The fixed thermal-magnetic mechanism provides two types of protection. The thermal bimetal element responds to sustained overloads with a long-time delay, while the magnetic element reacts instantaneously to clear high-fault short circuits.
What type of wire is compatible with the terminals on the 24449 breaker?
The screw clamp terminals are designed to accept copper conductors ranging from 14 AWG to 4 AWG. Ensure proper torque specifications are followed during installation to maintain a secure connection.
