MA1-B-24-450-1-A26-7-D Description

Short technical summary and product information.

The MA1-B-24-450-1-A26-7-D is a single-pole circuit breaker manufactured by Littelfuse Inc., designed for reliable overcurrent protection in electrical systems. Rated for 5 amperes at 250 volts, this component provides precise circuit safeguarding against excessive current flow. The breaker utilizes a magnetic hydraulic delay mechanism, which allows it to tolerate brief inrush currents while tripping promptly during sustained overload or short-circuit conditions.

 

Engineered for panel mounting applications, this unit incorporates a durable rocker actuator for manual operation. The non-illuminated design keeps the interface straightforward and cost-effective for standard industrial and commercial control panels. Its compact form factor and standardized mounting configuration facilitate easy integration into existing equipment layouts.

 

Procurement teams should verify terminal type and operating temperature specifications directly with the manufacturer prior to finalizing system designs, as these parameters are not detailed in the available documentation. This breaker serves as a robust solution for protecting low-voltage DC and AC circuits where reliable thermal-magnetic protection is required.
