The Littelfuse DA1-B0-26-640-111-D is a single-pole magnetic circuit breaker with hydraulic delay, rated for 40A at 277V. It uses a lever actuator and is designed for DIN rail mounting, making it suitable for panel and equipment protection applications.
The magnetic hydraulic delay mechanism provides reliable overcurrent protection with a time-delay characteristic that helps avoid nuisance tripping during temporary inrush currents. The 1-pole configuration protects a single circuit branch.
This circuit breaker carries approvals from CSA, VDE, and UL, indicating compliance with recognized safety standards for industrial and commercial electrical equipment. The non-illuminated lever actuator provides clear manual on/off control.
With its DIN rail mounting format, this breaker integrates into standard industrial control panels and distribution boards, offering a compact solution for branch circuit protection in 277V systems.
