The Littelfuse BB4-B2-34-620-121-D is a 4-pole magnetic circuit breaker with hydraulic delay, designed for overcurrent protection. It is rated for 20A continuous current and 250V AC/DC, suitable for a variety of industrial and commercial applications.
This circuit breaker uses a magnetic hydraulic delay mechanism, providing reliable trip characteristics for handling inrush currents without nuisance tripping. The lever actuator allows for manual reset and clear indication of the breaker state.
The breaker is panel mounted, making it easy to integrate into control panels and enclosures. It is approved by CCC, CSA, UL, and VDE, ensuring compliance with international safety standards. The product is RoHS3 compliant and has MSL 1 (unlimited) moisture sensitivity.
The four-pole configuration allows for simultaneous protection of multiple phases or multiple circuits. This model is non-illuminated and comes in a robust package suitable for demanding environments.
The voltage rating is 250V.
