MD1-B-34-610-1-A12-B-B Description

Short technical summary and product information.

The Littelfuse MD1-B-34-610-1-A12-B-B is a single-pole magnetic hydraulic delay circuit breaker designed for reliable overcurrent protection. Rated at 10A and 250V, it uses a magnetic hydraulic delay mechanism that provides temperature-stable tripping performance, making it suitable for a wide range of operating conditions.

 

This breaker features a rocker actuator for easy manual operation and is designed for panel mount installation. The single-pole configuration is ideal for protecting individual circuits in industrial control panels, power supplies, and telecommunications equipment.

 

The compact design ensures straightforward integration into existing panel layouts. As a magnetic hydraulic type, it offers consistent trip characteristics without the thermal compensation issues found in thermal breakers. The non-illuminated actuator simplifies the user interface.
