How the BE-SRPE100A100 Substitute for Part #SRPE100A100 Solves GE Rating Plug Gaps

The BE-SRPE100A100 is a direct substitute for rating plug SRPE100A100. See how it restores current protection without replacing the whole breaker.

BE-SRPE100A100. Substitute for Part #SRPE100A100

The BE-SRPE100A100 is BRAH Electric’s direct substitute for General Electric part SRPE100A100, a 100A rating plug for GE Spectra Series molded case circuit breakers. The GE original is marked obsolete in the catalogue. When that plug is missing or damaged, the breaker has no valid rating and should not go back into service, even if nothing else is wrong with it. The substitute closes that gap: it sets a 100A rating on a breaker with a 100A sensor, in SEDA, SEHA, SELA, SEPA frames.

This guide gives the specification of the substitute, the other ratings for the same sensor, and the look-alike plugs that are easy to order by mistake.

What a rating plug gap is

A molded case breaker with an electronic trip unit can stay in service for decades. The rating plug is a separate, removable part, and it can go missing. Plugs get pulled during testing, moved between breakers, lost in a shutdown, or damaged when a breaker is handled. If the manufacturer no longer supplies the plug, a sound breaker is left without the one small part that defines its rating.

That is the gap. The usual alternatives are to replace the breaker or to rework the panel, both of which cost far more time than the part that is missing. A substitute plug that matches the original lets the existing breaker carry on. The wider subject is covered in the guide to what to do when industrial electrical parts become obsolete.

How the substitute matches the SRPE100A100

A rating plug works with the sensors in the breaker and the trip unit it plugs into. The sensors measure the current, and the plug fixes the ampere rating the trip unit works to, up to the sensor rating. For a substitute to be a direct replacement, it has to agree with the original on four points:

  • the plug rating, here 100A;
  • the sensor rating it is made for, here 100A;
  • the breaker frames it fits, here SEDA, SEHA, SELA, SEPA;
  • the trip unit, here Spectra RMS.

The BE-SRPE100A100 is listed with those four values, so it goes into the breaker in place of the original with no change to the breaker or the trip unit. The 100A plug on a 100A sensor is the full rating of that sensor.

Other ratings for the 100A sensor

A gap is sometimes also a chance to correct a rating. If the load on the circuit has been reduced, or the drawings show a rating below 100A, the same breaker can take a lower plug from the 100A group.

All four are listed for a 100A sensor, the same four frame types and the Spectra RMS trip unit. Replace like for like unless the change of rating has been approved by whoever is responsible for the system design.

Plugs that are close to the SRPE100A100 but not the same

Three kinds of near miss cause most wrong orders: the top plug of the sensor below, the plugs of the sensor above, and a 100A plug made for a different Spectra frame.

The BE-SRPF250A100 deserves a second look. It is also a 100A plug, but it is listed for a 250A sensor in SFDA, SFHA, SFLA and SFPA frames. It is a different part from the SRPE100A100 and should not be ordered for an SE-type breaker. The same caution applies between sensor ratings in one frame: a breaker with a 150A sensor takes the SRPE150A plugs, and a breaker with a 60A sensor takes the SRPE60A plugs. The 60A part is described in the BE-SRPE60A60 rating plug guide.

The sensor rating in the table is the value the catalogue gives as the maximum frame amperage for each plug. For anything not in the table, call (855) 355-2724 with the part number.

What to check on the breaker before ordering

  • The catalogue number on the breaker label. For this plug it begins with SEDA, SEHA, SELA or SEPA.
  • The sensor rating marked on the breaker. It must be 100A.
  • The label on the old plug, if you still have it: SRPE100A100.
  • The trip unit type: Spectra RMS.
  • The rating the circuit calls for. Confirm 100A against the panel schedule or one-line diagram.

Compare the photos and datasheet on the BE-SRPE100A100 product page with the plug opening on your breaker. If the plug does not push in easily by hand, do not force it. Recheck the frame type and sensor rating.

Substitute plug or new breaker

Fitting a substitute plug makes sense when the breaker itself is healthy: it operates freely, shows no heat damage, and has only lost its plug. In that case the breaker, its mounting and its connections stay as they are.

A plug does not repair a breaker. If the breaker has a history of unexplained trips, a damaged case, or a mechanism that binds, have it inspected and tested before spending money on parts. NFPA 70B is the standard that covers maintenance of electrical equipment.

BRAH Electric designs its parts in-house and tests them at its facility in Carlsbad, California. It is an aftermarket manufacturer and is not an authorized distributor for General Electric. Rating plugs come with a 2-year warranty from the invoice date. In-stock orders received before 3:00 PM Pacific ship the same business day, and shipping is calculated at checkout.

Safety when fitting the plug

Fit or remove a rating plug only with the breaker open and the circuit de-energized and locked out. Verify the absence of voltage before touching the breaker. The work is for qualified personnel following the breaker manufacturer’s instructions and the practices in NFPA 70E.

BE-SRPE100A100 FAQs

What is the purpose of a rating plug in a circuit breaker?

It sets the ampere rating of an electronic trip breaker, within the limit of the sensors fitted to the breaker.

Is the BE-SRPE100A100 a direct replacement for the SRPE100A100?

Yes. The catalogue lists it as a direct replacement with the same 100A rating, 100A sensor, frame types and trip unit. No modification to the breaker is involved.

Why is the SRPE100A100 hard to find?

The catalogue marks the GE original as obsolete, while many of the breakers it fits are still in service. That is the reason substitutes are made.

Will the BE-SRPE100A100 fit a 150A Spectra breaker?

It is listed for a 100A sensor. A breaker with a 150A sensor takes a plug from the SRPE150A group: 110A, 125A or 150A.

Is an SRPF250A100 the same as an SRPE100A100?

No. Both are 100A plugs, but the SRPF250A100 is listed for SF-type frames with a 250A sensor.

Who can help confirm the right plug?

Call BRAH Electric on (855) 355-2724, Monday to Friday, 6AM to 5PM Pacific, with the breaker catalogue number and the number on the old plug.
