The FH26070BC Square D Circuit Breaker features a robust 2-pole configuration, rated at 70A for 600/347V applications. Ideal for commercial and industrial use, this high-performance breaker ensures reliable protection for your electrical systems. Designed for use in BC PH I Line setups, it guarantees safety and efficiency for your power needs.
The FH26070BC is designed for Square D I-Line (Phase I / BC-type) commercial and industrial panelboards that accept FH-frame plug-in breakers at 600/347V. It is not compatible with Square D QO or Homeline residential loadcentres. Since compatibility depends on your specific panel's bus and enclosure, we recommend sending us your panel model number so we can confirm the fit before you order.
The Square D FH-frame I-Line series is an older commercial/industrial product line, and availability of specific ratings like the 70A 2-pole FH26070BC can be limited through standard distribution channels. Northern Breaker Group specializes in hard-to-find and obsolete breakers — contact us for current stock availability and lead times.
The 18kA interrupting capacity (AIC) means the FH26070BC can safely clear a fault current of up to 18,000 amperes without catastrophic failure. For commercial and industrial installations at 600/347V, you must verify that the available fault current (short-circuit current) at the point of installation does not exceed 18kA — your engineer or electrical contractor can confirm this from a short-circuit study. If your system has higher available fault current, a higher-AIC rated breaker would be required.
