Predictika · Electrical equipment orders: molded case circuit breakers

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

An AI sales agent puts together an order for an HGM-type molded case circuit breaker from HYUNDAI ELECTRIC's HG-Series catalog: the frame and type, the rated current, the pole count, the short-circuit current and load at the site, the cabinet temperature and altitude, and the accessories. Before it goes out, the agent sends the order to Predictika, which checks it against a declarative model of the published tables and returns a verdict, every reason and the figures it computed.

Scope: HGM-type molded case circuit breakers, 32 to 800 AF: type and breaking capacity, rated current and dial, temperature and altitude derating, accessories and plug-in rules. See everything this validator covers

This validator models orders for one product line, the HGM-type breakers in the public HYUNDAI ELECTRIC HG-Series MCCB and ELCB catalog, using its selection, derating and accessory tables, not just the scenarios shown below.

  • Type and breaking capacity — the ten frames from HGM30 to HGM800 and the E, S, H and L breaking-capacity types offered on each, the ultimate breaking capacity at the system voltage, the rated currents listed per frame, and the pole counts offered.
  • Current and derating — the current-setting dial, the current the breaker carries at the cabinet temperature (10 to 70 degrees C) and at altitude (up to 5,000 m, with the voltage limit at altitude), compared with the load.
  • Accessories and plug-in types — the motor operator, mechanical interlock, terminal extensions, DIN rail adapter and undervoltage trip delay, and the plug-in types (TDM, TDF, TDA), each only on the frames and pole counts the catalog lists.
  • Stated figures — the breaking capacity and carrying current the agent states are compared with the catalog on every call.

Any order for these breakers that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (the catalog has none, so this validator produces no price build-up or line-item quote), earth leakage breakers and other series, trip-curve and coordination studies, cable and busbar sizing, and the 4-pole neutral arrangements beyond what the catalog lists.

The AI sales agentBuilds the breaker order from the conversation and says it is ready.

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
Breaking capacity that depends on frame, type and voltageOnly with care
Each frame and type has six voltage ratings; that is a grid of numbers to load and keep in step with the catalog, and a missed cell lets an under-rated breaker through.		The rating is looked up from the frame, type and voltage on every call and compared with the fault current.
A current rating that falls with temperatureOnly with workarounds
The current a breaker carries drops as the cabinet gets hotter, by a different curve for each frame group; a rule has to read the temperature and the frame together, which a single rated-current attribute cannot express.		The carrying current is computed from the frame, rating and temperature, then compared with the load.
Accessories that exist on some frames and pole counts onlyOnly with care
The motor operator, interlock, terminal extensions and DIN adapter each have their own list of frames and poles; each is a separate rule keyed to a model list.		Frame, poles and accessories are in one request and checked together.
Stated figures that disagree with the catalogOnly with care
The figures the agent states are free-entry fields; a rule can compare them with the catalog, but only if someone writes and maintains it for every frame.		The stated figures travel with the order and are compared with the computed ones on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is 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
Click to expand
    
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.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent puts together an order for an HGM-type molded case circuit breaker from HYUNDAI ELECTRIC's HG-Series catalog: the frame and type, the rated current, the pole count, and more. Before it goes out, the agent sends the order to Predictika, which checks it against a declarative model of the published tables and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote an HD Hyundai Electric HGM125 type S molded case circuit breaker, 2 poles, rated 125 A, at 380 V. The site has a prospective short-circuit current of 15 kA and a load of 90 A, in a cabinet at 40 degrees C at 1,000 m altitude. The rest of the request is on screen. The quote states a breaking capacity of 26 kA and a carrying current of 125 A at the site temperature.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with two findings, all in one answer. The motor operator is listed for 3-pole and 4-pole breakers only; the order has 2 poles. The DIN rail adapter is listed for the HGM30, HGM50 E/S, HGM60 and HGM100 only.
    6. 
      
  6. The validator returned two 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.
    7. 
      
  7. What this shows: for accessories that exist on some frames and pole counts only, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the model to HGM100 type S, the rated current to 100 A, the stated breaking capacity to 20 and the stated carrying current to 100.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. The motor operator is listed for 3-pole and 4-pole breakers only; the order has 2 poles.
    12. 
      
  12. One finding cleared. Still blocking: motor operator not offered on 2 poles.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the poles to 3.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared.
    18. 
      
  18. Two problems caught in one call, fixed in two passes, 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.
    19.
