Predictika · Automotive blade fuse orders

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

An AI sales agent prepares an order for 32 V DC automotive blade fuses with the series, ampere rating, plating, package size, circuit voltage, available fault current, ambient temperature and the continuous load. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public datasheets and returns a verdict, every reason and the figures it computed.

Scope: Littelfuse ATOF, MINI and MAXI blade fuse orders: ampere rating offered per series, plating and package size, 32 V DC rating, interrupting rating and the ambient-temperature derating of the continuous load. See everything this validator covers

This validator models orders for three Littelfuse 32 V DC blade fuse series (ATOF 0287, MINI 0297 and MAXI 0299), not just the scenarios shown below.

  • Ampere ratings — each series is offered in its own list of ratings (ATOF 1 to 40 A, MINI 2 to 30 A, MAXI 20 to 80 A); a rating the series does not list is blocked.
  • Plating and package size — the datasheet ordering tables list which plating comes in which package size for each series; a combination not listed is blocked, and a stated piece count is compared with packs times package size.
  • Voltage and fault current — the three series are rated 32 V DC with an interrupting rating of 1000 A at 32 V DC; a circuit above either is blocked.
  • Temperature derating — the continuous load is compared with the maximum load the datasheet table gives for that fuse at the ambient temperature (the next column at or above it); a temperature outside the table is blocked.

Any order for these three series that touches these rules is in scope — not only the scenarios pictured here. Not covered: shunt versions, other Littelfuse fuse families, holders, wire and terminal effects, and prices (no public price list was used).

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 the series does not offerOnly with care
A per-series list of valid ratings that has to be written and maintained for each series.
The series and the rating are in one request and checked on every call.
A load that is too high for the ambient temperatureOnly with workarounds
The limit comes from a two-way table of rating by temperature; it takes a lookup table or many formulas, kept for each series.
The load, rating, series and temperature are compared with the datasheet table on every call.
A plating and package combination that is not listedOnly with care
Each series has its own ordering table, so each needs its own validation rule.
Series, plating and package size are checked together on every call.
A piece count that disagrees with packs times package sizeOnly with workarounds
The count is a derived figure; checking a stated total against it takes extra formulas that interact with the rest.
The stated piece count is a field in the request and is compared with the computed one.

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 continuous load is 14.5 A; the datasheet gives 14 A as the maximum load for this fuse at the ambient temperature.
2The continuous load is 7.5 A; the datasheet gives 7 A as the maximum load for this fuse at the ambient temperature.
3The ambient temperature of 126 degrees C is outside the datasheet derating table for this series.
4The ambient temperature of -41 degrees C is outside the datasheet derating table for this series.
5The continuous load is 15 A; the datasheet gives 14 A as the maximum load for this fuse at the ambient temperature.
6The ATOF series is not listed in the 50 A rating.
7The continuous load is 2 A; the datasheet gives 1.9 A as the maximum load for this fuse at the ambient temperature.
8The ambient temperature of 101 degrees C is outside the datasheet derating table for this series.
9The MINI series is not listed in the 1 A rating.
10The MINI series is not listed in the 35 A rating.
11The continuous load is 40 A; the datasheet gives 35 A as the maximum load for this fuse at the ambient temperature.
12The MAXI series is not listed in the 10 A rating.

The text of the narrated walkthrough, step by step.

  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order for 32 V DC automotive blade fuses with the series, ampere rating, plating. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the figures in the public datasheets and returns a verdict, every reason and the figures it computed.
  2. I will start with the first request by the agent.
  3. The agent says. Please quote 20 packs of 10 tin plated Littelfuse MAXI blade fuses rated 60 A (200 pieces in all), for a 24 V DC circuit with a continuous load of 40 A. The order states 100 pieces. The rest of the request is on screen.
  4. Before it goes out, the agent calls the validator.
  5. Blocked, with three findings, all in one answer. The datasheet ordering table does not list the MAXI series in Tin plating in a package of 10. The continuous load is 40 A; the datasheet gives 35 A as the maximum load for this fuse at the ambient temperature. The order states 100 pieces; 20 packs of 10 come to 200.
  6. The validator returned three 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. What this shows: for a piece count that disagrees with packs times package size, a rules-based CPQ can do this only with workarounds.
  8. Now the agent resubmits.
  9. The corrected request. It changes the rating to 80 A and the stated pieces as to 200.
  10. It calls the validator again.
  11. Still blocked, with one finding, all in one answer. The datasheet ordering table does not list the MAXI series in Tin plating in a package of 10.
  12. Two findings cleared; still blocked on plating and package size not offered.
  13. The agent resubmits once more.
  14. The revised request. It changes the plating to silver.
  15. It calls the validator once more.
  16. This time the validator clears it.
  17. The earlier finding is cleared, and the validator's figure matches the quote.
  18. Three 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.
