Gridboss BSB 90A AC Circuit Breaker for Flexboss 21K

GridBOSS BSB 90A AC Circuit Breaker for FlexBOSS21K — Product Summary

The GridBOSS BSB 90A AC Circuit Breaker is a dedicated AC protection device engineered for use in EG4 energy systems, specifically sized for the FlexBOSS21K hybrid inverter when tied into a GridBOSS power distribution configuration. This breaker provides essential overcurrent and short-circuit protection for the AC output circuit between the inverter and the load center or main service panel, helping safeguard the inverter, wiring, and connected loads under fault or overload conditions.

Key Features

Properly Sized Protection

• Rated Current: 90 amps, matching the AC output and breaker requirements for the FlexBOSS21K inverter system to maintain safe operation and code compliance.

System Compatibility

• Designed for use with EG4 FlexBOSS21K hybrid inverters when integrating AC output into a GridBOSS panel or distribution assembly.

Safety & Standards Compliance

• UL-rated breaker constructed to meet relevant electrical safety standards (e.g., UL489).

• Engineered for reliable performance in residential and light commercial environments.

High Interrupting Capacity

• Rated to safely interrupt fault currents at levels typical in residential electrical systems, reducing risk of damage to the inverter and wiring.

Trip-Free Mechanism

• Automatically trips under overload or short-circuit conditions—even if the breaker handle is held in the on position—ensuring safety is maintained.

Split-Phase Nominal Voltage

• Intended for 120/240 VAC split-phase systems commonly used in U.S. residential installations.
