Eaton SRA – Frequently Asked Questions

1) Will the Eaton SRA spring release work on any Series NRX breaker, or is it frame-specific?
The SRA spring release is built for Eaton Series NRX breakers with a Universal frame, so one part number covers the compatible NRX frame sizes rather than requiring a different accessory per frame. If the breaker you are servicing is not a Series NRX with a Universal frame, this is not the accessory for it.
2) What control voltage does the Eaton NRX SRA spring release need?
It is rated 110-127 Vac/dc at 50-60 Hz, so it can be driven from either an AC or a DC control power source in that band. Standard 120 V control power falls inside the range. If your control circuit runs at 24 V, 48 V or 240 V, this version will not match and you need the spring release rated for that voltage.
3) Does the SRA accessory work with Digitrip trip units?
Yes. The spring release is specified for use with Digitrip trip units on Series NRX breakers, so it coordinates with the breaker's electronic trip unit for the trip action rather than working independently of it.
4) What does a spring release actually do on a circuit breaker, and how is it different from a shunt trip?
A spring release gives a spring-driven release action on the breaker, letting the breaker be operated in a controlled, repeatable way for testing, maintenance, or a protective response. Eaton catalogues the SRA under spring releases as a Series NRX circuit breaker accessory, and it supports remote or manual tripping of the breaker from the control circuit.
5) Can I add the SRA spring release to an existing NRX breaker already in service, or is it only for new gear?
Both. Eaton lists the SRA for new installations, retrofit work, and ongoing breaker maintenance programs on Series NRX breakers, so it is a field-added accessory for gear already installed as well as a factory-specified option.
6) What exact part number should I order for the Eaton NRX spring release at 120 V control power?
Order Eaton part number SRA. That is the single model offered for the Series NRX Universal frame spring release rated 110-127 Vac/dc, 50-60 Hz, so there are no finish or size choices to specify beyond confirming your control voltage falls in that band.
