Product FAQs
7 answersIs the Eaton FAZ-B16/1-NA-SP rated as a branch circuit breaker or a supplementary protector?
The FAZ-B16/1-NA-SP is a UL 489 listed miniature circuit breaker, meaning it is fully rated for branch circuit protection. It can also be used in applications where UL 1077 supplementary protectors are permitted.
What does the B-curve trip characteristic mean for this Eaton FAZ-NA breaker?
The B-curve magnetic trip point is set between 3 and 5 times the rated current. This makes it ideal for applications with low inrush currents, such as resistive loads, lighting circuits, and control circuits where high startup surges are not expected.
Can the FAZ-B16/1-NA-SP be reverse fed?
Yes, power to this Eaton FAZ-NA series circuit breaker can be fed from either the line or the load side without affecting its protective function.
How does the FAZ-B16/1-NA-SP mount inside a control panel?
This miniature circuit breaker snaps directly onto a standard 35mm DIN rail, allowing for quick installation in industrial control panels and branch service applications.
What type of wire connections does the FAZ-B16/1-NA-SP accept?
It is equipped with standard box lug terminals that feature captive screws to prevent loss during installation. The lugs accept 18 to 6 AWG for a single wire, or 18 to 10 AWG when landing two wires.
Is the Eaton FAZ-B16/1-NA-SP a current-limiting circuit breaker?
Yes, it features a current-limiting design that provides fast short-circuit interruption. This reduces the peak let-through energy, offering superior protection against potential damage to the downstream circuit.
Does this breaker provide visual indication of its trip status?
Yes, the FAZ-B16/1-NA-SP features a color-coded indicator that provides immediate visual confirmation of the contact status, displaying red for ON and green for OFF.
