Product FAQs

8 answers
When should I use the Eaton FAZ-C40/1-SP supplementary protector?

A supplementary protector adds overcurrent protection within equipment. Select the Eaton FAZ-C40/1-SP when the equipment's protection design calls for supplemental protection of an individual circuit.

How should I use the 40A current rating when selecting this protector?

The rated current is 40A. Choose it when the circuit's load characteristics and conductor protection requirements call for a 40A protector.

Can I select this protector for either AC or DC operation?

It is rated 277VAC and 48VDC. Use the rating corresponding to your circuit type and verify that the circuit voltage stays within that rating.

How do I check whether its interrupting rating is sufficient?

The interrupting rating is 15kAIC at 277VAC. For a 277VAC installation, compare the available fault current at the installation point with this rating; the available fault current must not exceed it.

How do the C curve and fixed thermal-magnetic trip affect selection?

The thermal trip provides long-time overload response, while the magnetic trip provides instantaneous short-circuit response. Both settings are fixed, so select the C curve to suit the load's starting-current behavior rather than planning on field adjustment.

How is this protector mounted and operated?

It mounts on DIN rail and uses a toggle actuator. Plan the mounting location with space for conductor routing and access to the toggle.

What does the single-pole configuration mean for circuit design?

The single pole provides overcurrent protection for one circuit conductor. Select it when the circuit design calls for single-pole protection.

Does the AWG 18 minimum wire size determine the conductor size I should install?

AWG 18 is the minimum wire size for termination. Size the conductor for the circuit current and applicable installation rules, rather than using the terminal minimum as the circuit-sizing requirement.
