Predictika · Moulded case circuit breaker quotes

An AI sales agent's circuit breaker quote, checked before it goes out

An AI sales agent prepares a quote for moulded case circuit breakers: a frame, a current rating, poles, a trip unit, a breaking capacity, accessories such as a motor operator or a voltage release, the site fault level and a discount. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the DN-Line frames and returns a verdict, every reason and the totals it computed.

Scope: L&T DN-Line moulded case circuit breakers (frames DN0, DN1, DN2 and DN3): frame and rating, breaking capacity against the site fault level, trip unit, accessories and discounts. See everything this validator covers

This validator models DN-Line breaker quotes of this kind, not just the scenarios shown below.

  • Frame and rating — the current range of each of the four frames, 3-pole or 4-pole breakers and a switched neutral, and the total amperes the quoted breakers add up to.
  • Breaking capacity and trip unit — the highest breaking capacity each frame offers, the site fault level against it, and which trip unit (thermal-magnetic or electronic) each frame takes.
  • Accessories and approvals — the shunt trip, undervoltage release, motor operator and rotary handle combinations that are allowed, and the thin fault-level margin, high ambient temperature and discount that need a person to approve.

Any DN-Line breaker quote that touches these rules is in scope — not only the scenarios pictured here. The DN-Line frame names, 3-pole and 4-pole breakers, thermal-magnetic release, IS/IEC 60947-2 and the 25 to 70 kA breaking-capacity classes come from public distributor and marketplace listings; the frame current ranges, the highest breaking capacity per frame, trip unit by frame, accessory compatibility, the fault-level margin, the ambient limit and the discount thresholds are modeled from comparable breaker families and are not published by Larsen & Toubro. No prices are modeled. Not covered: other L&T breaker ranges, air circuit breakers, protection relays, installation and taxes.

Where rules-based CPQ gets it wrong

Click to expand

Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

What the validator caughtTypical rules-based CPQPredictika
A rating that must fit the frame chosenOnly with care
Each of the four frames has its own current range, so every frame needs a rule that compares it with the rating, both above and below.
The frame and the rating are fields of one request and are checked together on every call.
A breaking capacity that depends on the frame and the siteOnly with care
The highest capacity differs by frame, and it must also exceed the site fault level, with a thin margin sent for review, so several figures are compared at once.
The frame, breaking capacity and fault level are in one request and checked together on every call.
Trip unit and accessory combinationsOnly with care
Electronic and thermal-magnetic trip units are limited by frame, a motor operator is not offered on one frame, and some accessories exclude each other, so each pair needs its own rule.
The frame, trip unit and every accessory are checked together on every call.
A stated total that must match the quoted breakersOnly with workarounds
The total amperes come from the quantity times the rating, so a separate rule must recompute it and compare it with the stated figure.
The stated total is a field of the request and is compared with the computed total on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as a step is saved or completed, so a rep often fixes one error and meets the next.
All findings come back together, whatever order the choices arrived in.

What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

1The rating is 125 A; the selected frame goes up to 100 A.
2The rating is 320 A; the selected frame goes up to 250 A.
3The rating is 100 A; the selected frame starts at 160 A.
4The requested breaking capacity is 70 kA; the selected frame offers at most 50 kA.
5The site fault level is 40 kA; the breaker breaking capacity is only 36 kA.
6The site fault level of 36 kA is within 10 percent of the 36 kA breaking capacity; an engineer should confirm.
7The site fault level of 33 kA is within 10 percent of the 36 kA breaking capacity; an engineer should confirm.
8The selected trip unit is not offered on this frame (electronic from DN2 up, thermal-magnetic up to DN1).

Narration transcript

The text of the narrated walkthrough, step by step.

  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a quote for moulded case circuit breakers: a frame, a current rating, poles, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the DN-Line frames and returns a verdict, every reason and the totals it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote three 160 A breakers on the DN0 frame, 3-pole, electronic trip unit, with a breaking capacity of 50 kA. The quote states 600 A in total. The rest of the request is on screen.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with eight findings, all in one answer. The rating is 160 A; the selected frame goes up to 100 A. The requested breaking capacity is 50 kA; the selected frame offers at most 36 kA. The selected trip unit is not offered on this frame (electronic from DN2 up, thermal-magnetic up to DN1). The other five are on screen.
  6. The validator returned eight blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other and against the stated total.
  7. What this shows: for a stated total that must match the quoted breakers, a rules-based CPQ can do this only with workarounds.
  8. Now the agent resubmits.
  9. The corrected request. It changes the frame to DN2, the poles to 4-pole, the undervoltage release to no, the rotary handle to no and the total stated on the quote to 480.
  10. It calls the validator again.
  11. This time the validator clears it.
  12. All eight earlier findings are cleared.
  13. Eight problems caught in one call, fixed in one pass, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
