The circuit breaker has the following features:
• Short-circuit protection.
• Protection against battery cabinet and ups connection errors (polarity reversal +/-).
The battery circuit breaker boxes are of the same size for the 10 kVA to 30 kVA UPS, but switch
capacity are different.
The information shown in Figure 22 applies to both sizes.
The BCB box contains a battery isolating circuit breaker.
