Product FAQs
6 answersIs the Eaton FAZ-B40/1-SP rated for branch circuit protection?
No, the FAZ-B40/1-SP is a UL 1077 supplementary protector. It is designed to provide additional overcurrent protection within appliances or control panels where a UL 489 branch circuit breaker or fuse is already installed upstream.
What applications are best suited for the B trip curve on this breaker?
The B curve magnetic trip point is set at 3 to 5 times the rated current. This is ideal for applications with very low inrush currents, such as resistive heating loads, control circuits, PLCs, and long wiring runs that require sensitive short-circuit protection.
What wire sizes do the terminals on the FAZ-B40/1-SP accept?
The box terminals can accommodate a single conductor from 18 AWG to 6 AWG, or two conductors from 18 AWG to 10 AWG.
What are the terminal torque specifications for this supplementary protector?
The tightening torque depends on the wire gauge: use 21 lb-in for 18-12 AWG, 25 lb-in for 10-8 AWG, and 36 lb-in for 6 AWG wire.
Can the FAZ-B40/1-SP be used in DC control circuits?
Yes, this single-pole supplementary protector carries a DC voltage rating of up to 48 VDC, making it suitable for low-voltage DC control and automation panels.
What does the -SP suffix mean in the FAZ-B40/1-SP part number?
The -SP suffix indicates single packaging. The breaker itself is identical in form, fit, and function to the standard FAZ-B40/1 supplementary protector.
