MT1-S-10-440-P-A21-B-C Description

Short technical summary and product information.

The Littelfuse MT1-S-10-440-P-A21-B-C is a single-pole magnetic hydraulic delay circuit breaker designed for reliable overcurrent protection. It is rated for 4A continuous current at 250V AC/DC, making it suitable for a variety of low-power circuit protection applications.

The magnetic hydraulic delay mechanism provides time-delayed tripping, allowing for momentary inrush currents without nuisance trips. The push-pull actuator offers manual reset capability, and the breaker mounts directly to a panel for secure installation.

With its compact 1-pole design and panel mount form factor, this circuit breaker is easy to integrate into control panels, power distribution units, and other equipment requiring resettable overcurrent protection.
