BKA160205 SQUARE D 1P 20A 600Y/347V C PH I LINE

The BKA160205 uses Square D's I-Line plug-in mounting style, so it is designed for Square D I-Line panelboards and switchboards in commercial and industrial installations. It is not compatible with residential QO or Homeline loadcentres. Contact our team with your panel model and we'll confirm the fit.

The 600Y/347V rating means this breaker is specifically engineered for Canadian commercial distribution systems wired in a wye configuration (347V phase-to-neutral, 600V phase-to-phase). It is not the correct breaker for a standard 120/240V single-phase residential system. Using a higher-voltage-rated breaker on a lower-voltage system may be acceptable in some cases, but always verify with your panel specs and a licensed electrician.

Availability of specific BKA-frame I-Line breakers can vary. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the BKA160205 is no longer in regular production, we can often source new, reconditioned, or surplus stock.
