MF2-B-34-620-1-BF4-B-C Description

Short technical summary and product information.

The MF2-B-34-620-1-BF4-B-C is a specialized circuit breaker designed for robust electrical protection in demanding environments. Manufactured by Littelfuse Inc., this component delivers a continuous current rating of 20 amperes with a maximum voltage rating of 250 volts. The unit incorporates a two-pole configuration, allowing for simultaneous interruption of multiple conductors within a single enclosure.

 

Engineered for reliable performance under varying load conditions, the breaker utilizes a magnetic hydraulic delay trip mechanism. This specific actuation method provides precise overload protection while tolerating brief inrush currents without nuisance tripping. The integrated neon illumination system operates at a nominal 250 volts, offering clear visual status indication directly on the front panel.

 

Installation is facilitated through a dedicated panel mount design, ensuring secure attachment to control panels or equipment enclosures. The rocker-style actuator provides tactile switching capability alongside the protective functions. This combination of electrical ratings, mechanical durability, and visual feedback makes the component suitable for industrial machinery, power distribution units, and heavy-duty equipment applications where circuit integrity and operator awareness are critical.
