The BA1-B0-24-640-521-C is a single-pole magnetic (hydraulic delay) circuit breaker manufactured by Littelfuse Inc. It is rated for a continuous current of 40A at a voltage of 277V. The hydraulic delay mechanism provides time-delayed overcurrent protection, making it suitable for circuits with moderate inrush currents.
The breaker is designed for panel mount installation and uses a lever actuator for manual reset and switching. It is not illuminated, which is typical for industrial circuit breakers where visual indication is not required. The single-pole configuration allows it to protect one phase of a circuit.
This circuit breaker is commonly used in branch circuit protection, industrial control panels, and power distribution systems. Its compact panel mount design integrates easily into a variety of electrical enclosures.
