BGA161103 SQUARE D 1P 110A 347/600V B PH I LINE

Yes — the 347/600 V rating makes the BGA161103 an excellent fit for Canadian commercial and industrial applications. In Canada, 347/600 V wye systems are the standard for large commercial buildings, where 347 V is the phase-to-neutral voltage used for fluorescent and LED lighting circuits, and 600 V is the phase-to-phase voltage used for motor and distribution circuits. This breaker is purpose-built for that environment.

The BGA161103 carries an interrupting rating of 18 kA at 347/600 V. Per the Canadian Electrical Code (CEC), the breaker's interrupting capacity must equal or exceed the available fault current at the point of installation. If your system's calculated fault current exceeds 18 kA, a higher-interrupting-rated breaker will be required. We recommend verifying your fault current with a qualified electrician or engineer before installation.
