The 10 features that turn 4 tools into 1.
KKE Circuit is built around the actual workflow of an electrical, process or automation engineer. These are the features that pull schematics, P&IDs, panel layouts and BOMs into a single tool — for teams in Worldwide.
For Worldwide: KKE Circuit is available across Global in English. Region: Global (INT).
1. Multi-variant symbols
One library part stores up to seven variants of itself — schematic, single-line (SLD), three-phase, P&ID, control, panel front view, terminal. Add a Siemens 3RT2027 contactor once; it shows up correctly on schematic, SLD, panel layout and terminal drawings without redrawing.
2. Switch the electrical standard, the project follows
Choose IEC, UL 508A (NFPA 79 / NEC), cUL/CSA, CSA C22.2 No. 14, AS/NZS 3000 or NEMA ICS at project creation. The wire colours, reference designators (K vs CR for contactor), default net labels (24VDC vs +24V) and terminal-strip wire palette switch project-wide.
3. P&ID lines auto-colour by fluid
To ISA-5.1 / ISO 10628. The kind attribute on a symbol pin (electric / air / oil / water) drives the line colour: water blue, oil red, air cyan, hydraulic. Engineers don't have to remember the convention.
4. Built-in cable sizer (IEC 60364-5-52)
Inputs: load (kW / kVA / A), voltage, cores, install method (A / B / C…), ambient temperature, length. Output: recommended copper PVC/XLPE cross-section in mm², with the rule it applied (Iz table, derating, grouping factor, voltage-drop check). One click to apply to the selected wire.
5. Terminal strips auto-generated
Assign components to physical panels in the Panel Manager. Wherever a wire crosses a panel boundary or panel ↔ field, the system generates a terminal row with a sequential per-panel number (X1, X2…), net name, internal/external references (e.g. K1:T1 ↔ M1:U1), the next sequential IEC or UL wire colour from the standard palette, plus cable ID and cross-section. Recomputed on demand — no stale wiring schedules.
6. PR-style drawing reviews
Request a review with optional revision label and notes. Reviewer sees the change set and decides: approve, request changes or reject. Both parties get notified. Full history of past reviews lives under the current one.
7. Read-only share — no login required
/view/<token> share links so contractors and clients can open the drawing on a phone, tablet or laptop without signing up. Optional expiry date. Folder and project shares at viewer / commenter / editor / owner level for collaborators who do have accounts.
8. Odoo integration
XML-RPC connection per organisation, encrypted API key, test-connection button. Sync product.product from Odoo into the parts library so reference designators map to your internal codes. Push the project BOM straight to Odoo as a mrp.bom for manufacturing planning. Optional SSO via Odoo credentials — users on existing deployments don't need a separate password.
9. Browser-native, nothing to install
Built on Konva.js. Works on Chrome, Edge, Safari, on a laptop, tablet, and on a phone for read-only viewing. No Java, no plug-ins, no admin rights, no IT ticket.
10. Engineering grid you actually want to use
Click-to-place from the symbol library, smart non-overlapping placement, drag-select with marquee, Manhattan-or-freeform wire routing (press R to flip the axis), auto-hop arcs over crossings, floating-net warnings, undo/redo command history, multi-sheet drawing packages with automatic Sheet X of Y, A0–A4 page sizes, customisable title block. Auto-save every 60 seconds.
