A more convenient, economical, and space efficient replacement for a DC isolator switch and fuse holder combination, this resettable MCB protects against overload, short circuit and reflux. This is a fully non polar product as it is designed to handle both positive and negative current flow.
One 4P breaker can simultaneously protect positive and negative connections of one DC load. Heavy duty, high quality circuit breaker for residential and industrial applications.
The BB1-63 modular miniature circuit breakers (MCB) can be used in DC circuits up to 1200 V. This unit is configured with inputs and outputs at the bottom of the product (see image and diagram 4A in the datasheet for a schematic view).
Compliant with IEC 60947-2 / GB / T14048-2. TUV/CB/CE certified. 6kA breaking capacity. Arc flash barriers. Accepts up to 25mm² connections. Max 2.5 Nm torque.
