The Littelfuse BT1-B2-52-610-221-D is a single-pole magnetic hydraulic delay circuit breaker designed for overcurrent protection in a variety of applications. It is rated for 10A continuous current and 277V AC operation, making it suitable for branch circuit protection in commercial and industrial settings.
The breaker uses a magnetic hydraulic delay mechanism, which provides precise tripping characteristics over a wide temperature range. The lever actuator allows for manual reset and on/off control. This component is panel-mounted, making it straightforward to integrate into control panels and distribution boards.
Approvals include CCC, CSA, UL, and VDE, indicating compliance with international safety standards. The unilluminated actuator is standard for this series. With a 1-pole configuration, it is ideal for single-phase circuits or individual branch protection.
