The Littelfuse DA1-B0-34-470-121-D is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in industrial and commercial applications. It is rated for 7A continuous current at 277V AC, providing reliable trip performance under short-circuit and overload conditions.
The magnetic hydraulic delay mechanism offers precise time-current characteristics, making it suitable for applications where inrush currents are present. The breaker features a lever actuator for manual reset and is intended for DIN Rail mounting, simplifying installation in control panels and distribution boards.
Approved by CSA, VDE, and UL, this circuit breaker meets international safety standards. It is non-illuminated and does not include auxiliary contacts or shunt trip options. The compact 1-pole design allows for efficient use of panel space.
