Pertanyaan yang Sering Diajukan
How do I select the correct amperage for my application?
Determine the continuous load of the circuit and select a breaker with an amperage rating equal to or greater than that load. Available ratings are 10 A, 15 A, 35 A, 50 A, 60 A, and 80 A.
What is the difference between the 10kA and 22kA interrupting ratings?
The interrupting rating indicates the maximum short-circuit current the breaker can safely interrupt. Choose 10kA for systems with lower available fault current, and 22kA for higher fault current scenarios, both at 120/240V AC. There is also a 10kA at 120V AC option for single-phase systems.
What are the available ground fault protection levels?
5 mA for people protection (GFI), 30 mA or 100 mA for equipment protection (EPD).
What is the maximum conductor length?
250 feet.
What standards do these breakers meet?
UL 489, UL 943 Class A, UL 1053, and CSA C22.2 (not applicable to 3-pole GFI).
