BSB Hydraulic-Magnet Circuit Breakers 50A~125A

Description

BSB hydraulic magnetic circuit breakers provide overcurrent and short-circuit protection for AC electrical systems rated up to 240V. These breakers utilize hydraulic-magnetic technology for consistent trip characteristics across varying ambient temperatures. The B3S series meets UL489 standards for residential applications with 10,000 AIC interrupting capacity at 240V.

Compatible with the EG4 GridBOSS microgrid interconnect device, these breakers install in the same port locations as Eaton BR breakers. The hydraulic-magnetic design eliminates thermal elements, reducing sensitivity to temperature variations that can cause nuisance tripping in extreme environments. Standard 1-inch mounting width fits GridBOSS hybrid inverter and smart load ports.

Select the appropriate amperage based on connected equipment:

• 50A: EG4 12kPV hybrid inverter connection
• 70A: EG4 18kPV hybrid inverter connection
• 90A: EG4 FlexBOSS21 hybrid inverter connection
• 125A: Generator input or high-capacity smart load ports
