The AF2-B0-44-620-343-D is a 2-pole magnetic hydraulic delay circuit breaker manufactured by Littelfuse Inc. This circuit breaker is rated for 20A continuous current at 250V AC/DC and uses a magnetic hydraulic delay mechanism for reliable overcurrent protection. The hydraulic delay provides time-delayed tripping for transient overloads while offering fast response to short circuits.
The breaker features a rocker actuator for manual reset and is designed for panel mount installation. With a 2-pole configuration, it can simultaneously disconnect both poles for complete circuit isolation. The breaker is approved by CCC, CSA, UL, and VDE, ensuring compliance with international safety standards. It is RoHS3 compliant, REACH unaffected, and has an MSL of 1 (unlimited).
This circuit breaker is suitable for use in power distribution, industrial equipment, and commercial appliances requiring reliable overcurrent protection. The non-illuminated rocker actuator provides clear visual indication of the breaker state. The magnetic hydraulic design ensures consistent performance.
