MA1-B-30-620-1-A26-B-C Description

Short technical summary and product information.

The MA1-B-30-620-1-A26-B-C is a single-pole magnetic hydraulic delay circuit breaker from Littelfuse. It is rated for 20A continuous current at 250V AC or DC. The breaker uses a hydraulic delay mechanism to provide time-delayed overcurrent protection, allowing for inrush currents without nuisance tripping. The actuator is a rocker style and is non-illuminated. This breaker is designed for panel mount installation and is approved under CCC, CSA, and UL1077 standards. It is suitable for branch circuit protection in industrial control panels, power distribution, and commercial equipment. The RoHS compliance status is indicated but unverified.
