The 30055-40 is a single-pole circuit breaker engineered by Littelfuse Inc. for robust electrical system protection. Rated for a continuous current of 40 amperes and operating at 12 volts DC, this component ensures reliable performance in low-voltage applications. The device features an automatic reset mechanism, allowing systems to resume normal operation immediately after a fault condition clears without manual intervention.
Constructed for durability, this circuit breaker utilizes a chassis mount configuration, facilitating secure installation within control panels or equipment enclosures. The metal break handle provides clear visual indication of the tripped state while offering a sturdy interface for manual resetting when required. With no integrated illumination, the design prioritizes functional simplicity and cost-effectiveness for industrial and commercial power distribution setups.
Engineers specifying this component can rely on its straightforward integration into 12V DC circuits requiring high-current protection. The automatic reset feature minimizes downtime in critical infrastructure, making it suitable for automotive, marine, telecommunications, and general industrial machinery applications where uninterrupted power delivery is essential.
