The FH36060 Square D 3P 60A 600V I-Line Circuit Breaker is designed for reliable performance in residential and commercial applications. This three-pole breaker provides optimal overload and short-circuit protection. Engineered for durability and ease of installation, it fits seamlessly into Square D I-Line panelboards, ensuring safe and efficient operation.
The FH36060 is designed for Square D I-Line panelboards and switchboards that use the I-Line plug-in bus system (e.g., NQ and NF series). It is not compatible with Square D QO or Homeline residential loadcentres. Contact us with your panelboard model and we'll confirm compatibility.
Sourcing availability can vary — the FH-frame I-Line breakers are an older Square D series and some configurations may be discontinued. Northern Breaker Group specializes in obsolete and hard-to-find breakers, so even if the FH36060 is no longer in regular distribution, we can often locate new, reconditioned, or surplus stock. Reach out to one of our counter locations in Calgary, Edmonton, or Vancouver for a quote.
The 18 kA (at 600 V AC) interrupting rating is the maximum fault current the FH36060 can safely clear. You'll need to verify that the available short-circuit current at your panelboard does not exceed 18 kA — your electrical engineer or a arc-flash/fault-current study can confirm this. If your system has higher fault levels, a higher-AIC frame in the I-Line family may be required. We're happy to help you identify the right option.
