Built for electrical engineers.
Multi-sheet schematic, SLD, power, terminal, wiring and earthing on the same project. Switch the standard, the wire colours and designators follow — for teams in Worldwide.
For Worldwide: KKE Circuit is available across Global in English. Region: Global (INT).
15 drawing types, one symbol library
Schematic / control, single-line diagram, three-phase power, motor starters (DOL, Star-Delta, VFD), switchgear and busbar, wiring with cable schedule, terminal drawings, panel front views, earthing, incomer drawings — all on the same project, sharing the same components and netlist.
Switch the standard, the project follows
Choose IEC 60617, UL 508A (NFPA 79 / NEC), cUL/CSA dual-marked, CSA C22.2 No. 14, AS/NZS 3000 or NEMA ICS at project creation. The wire colours, reference designators (K / F / M for IEC vs CR / FU / MTR for UL), default net labels (24VDC vs +24V) and the terminal-strip wire palette switch project-wide.
Cable sizer (IEC 60364-5-52)
Inputs: load (kW / kVA / A), voltage, cores, install method (A / B / C…), ambient temperature, length. The sizer returns the 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.
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. Recompute on demand — never a stale wiring schedule.
Cross-sheet net labels
Same name on different sheets means the same net. The netlist resolver reconciles connectivity across all sheets, flags floating nets (single pin) for review, and powers the cable schedule, terminal generation and PLC I/O list.
Multi-variant symbols
One library part stores up to seven variants of itself. Add a Siemens 3RT2027 contactor once; it shows up correctly on schematic, SLD, panel front view and terminal drawing — no redrawing.
