Product FAQs

6 answers
What panels and equipment is the FS240020ASR01 compatible with?

This F-Frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. As a unit-mount breaker, it bolts directly to the chassis or bus of compatible enclosures.

Can the FS240020ASR01 replace older Cutler-Hammer breakers?

Yes, this 20A F-Frame breaker can successfully replace older EHD2020 and FDB2020 models, provided the 14kAIC at 480VAC interrupting rating meets your specific system requirements.

What wire sizes are accepted by the terminals on this breaker?

The standard lugs accept wire gauges ranging from 14 AWG to 1/0 AWG. When installing, ensure conductors are properly torqued according to the specifications printed on the breaker faceplate.

Can this circuit breaker be used in direct current (DC) systems?

Yes, the FS240020ASR01 is rated for use in DC applications up to 250VDC, where it provides a 10kA interrupting capacity. This makes it suitable for specific industrial control and battery system applications.

What type of protection does the trip unit provide?

It features a non-interchangeable thermal-magnetic trip unit with fixed thermal and fixed magnetic settings. This delivers standard long-time and instantaneous (LI) overcurrent and short-circuit protection for commercial and industrial power distribution.

Does this breaker provide ground fault or arc fault protection?

No, this is a standard thermal-magnetic breaker. It does not include Ground Fault Circuit Interrupter (GFCI) or Arc Fault Circuit Interrupter (AFCI) capabilities, which are typically required for certain residential or specialized commercial circuits.
