Thermal conditions
State operating temperature, exposure duration and the expected local temperature at the connection. Request applicable test evidence.
Ceramic and PPS terminal blocks for wiring projects with elevated-temperature requirements. Compare YC023 and YC024 as separate constructions: temperature capability alone does not establish current capacity or a suitable complete installation.

| Construction | Selection focus | Series reference |
|---|---|---|
| Steatite ceramic terminals | YC023 lists two- and three-pole models with individual ratings of 20, 32 or 57 A at 450 V. The published working-temperature range is −40°C to +425°C. | YC023 |
| PPS two-pole connectors | YC024 lists a 2.5–4.0 mm² wire range, 3 A at 380 V and a working-temperature range of −40°C to +300°C. These values do not apply to the ceramic range. | YC024 |
The product temperature limit is not a rating for the attached wire or the complete assembly.
State operating temperature, exposure duration and the expected local temperature at the connection. Request applicable test evidence.
Specify current and voltage for the actual operating conditions. Confirm any required derating rather than combining independent maximum values.
Check wire insulation, conductor preparation and terminal hardware suitability for the intended environment.
Use model-specific fixing dimensions and pole layout. Confirm clearances, mechanical protection and installation instructions.
Send the YC023 or YC024 model, operating temperature, electrical load, wire details and quantities.
Prepare an enquiryAgree the specification and required evidence before placing your order.
Explore manufacturingSpecify material, model, poles and quantity.
Provide continuous and peak conditions, exposure duration and installation environment.
Include wire specification, mounting drawing and nearby components.
Agree required test documentation and sample evaluation before purchase.

OEM & PACKING
Build your high temperature terminal blocks order around the selected models, identification and supply requirements.
Specify material, model, poles and quantity.
Provide part numbers, label artwork and any batch or traceability information required for the order.
Specify quantities per model, individual packs, outer cartons and delivery destination.
No. YC023 and YC024 differ in construction, electrical ratings, pole arrangements and dimensions. Compare the complete selected-model specification.
No. It is the published upper working-temperature value for YC023. YC024 lists +300°C. Confirm the selected model and assembly requirements.
Do not assume this without supporting operating data. Provide the intended load and thermal conditions for model-specific confirmation.
No. YC007 Bakelite strips remain in Terminal Strips & Barrier Blocks. A material name alone is not a basis for assigning the same high-temperature rating.
Send the YC023 or YC024 model, operating temperature, electrical load, wire details and quantities. Include the exact model quantities, delivery destination and required documentation.
Send your part numbers, label artwork, pack quantities and shipment requirements. Feasibility, sample requirements, minimum quantities and lead time are confirmed for the requested models.
