SPIDER Automation PCT-218 8-Pole Quick Connection Terminal Block | PA66 Spring-Lever Electrical Wire Connector
Description
The SPIDER Automation PCT-218 8-Pole Quick Connection Terminal Block is a compact electrical connector designed for multi-conductor wiring in distribution boxes, junction boxes, electrical panels and equipment assemblies. Its eight-position configuration consolidates multiple conductor connection points into one terminal body, supporting organised wiring in installations where space and connection accessibility are important.
The terminal uses a spring-lever locking mechanism with individual operating levers for conductor insertion and release. Its housing is manufactured from modified PA66 nylon, while the internal contact components are stainless steel. This construction combines an insulating terminal body with a lever-operated spring connection arrangement.
The PCT-218 supports solid conductors from 0.08–2.5mm² and stranded conductors from 0.08–4.0mm². It has a stated rated voltage of 250V, rated current of 32A and operating temperature range of -20°C to +80°C. The terminal body has a specified length of 41mm.
Key Features

- Stranded Conductor Compatibility: Supports stranded wire cross-sections from 0.08–4.0mm².
- 250V Rated Voltage: Provides a stated voltage rating for compatible electrical applications.
- 32A Rated Current: Offers a stated current rating, subject to conductor size and installation conditions.
- Modified PA66 Housing: Uses a modified nylon insulating body for the terminal assembly.
- Stainless-Steel Contact Components: Incorporates stainless-steel contacts in the conductor connection assembly.
- Operating Temperature Range: Has a stated operating range of -20°C to +80°C.
- Compact Body: The 41mm specified length supports space-conscious wiring arrangements.
- Multiple Colour Options: Available in grey and orange versions.
Terminal Configuration & Connection Mechanism
The PCT-218 is identified as an 8-pole terminal connector with eight contact positions. Each position uses a spring-lever mechanism to control conductor clamping. Operating the corresponding lever allows the conductor to be inserted or released without relying on a conventional screw-clamping arrangement.
For connection, operate the relevant lever, insert the prepared conductor into its designated terminal position and close the lever to engage the spring clamp. Check conductor retention after connection. Confirm the internal electrical arrangement and pole assignments from the product wiring diagram before connecting different circuits.
Housing & Contact Construction
The terminal body is manufactured from modified PA66 nylon, providing the insulating enclosure for the internal connection assembly. Stainless steel is identified as the contact material. The spring-lever design provides controlled conductor clamping while keeping the connection points accessible for wiring and maintenance.
The compact construction is suitable for organised conductor connections in electrical enclosures and equipment assemblies. The specified operating temperature range is -20°C to +80°C.
Electrical & Conductor Compatibility
The PCT-218 accommodates different conductor types with separate cross-section ranges: 0.08–2.5mm² for solid wire and 0.08–4.0mm² for stranded wire. Its stated rated voltage is 250V and rated current is 32A.
Conductor selection must account for the circuit load, conductor type, enclosure conditions and applicable electrical installation requirements. Do not treat the rated current as suitable for every supported wire size under all operating conditions.
Mechanical Design & Dimensions
The PCT-218 has a specified body length of 41mm. Its compact terminal arrangement is intended to consolidate eight conductor connection positions within a single assembly. Verify the complete body dimensions and available installation clearance before incorporating the terminal into a panel or enclosure layout.

Connection & Operating Recommendations
- Isolate the Power Supply: Disconnect the electrical supply and verify that the circuit is de-energised before wiring or servicing the terminal.
- Select the Correct Conductor: Use solid conductors within 0.08–2.5mm² or stranded conductors within 0.08–4.0mm².
- Prepare the Wire Ends: Strip insulation carefully and avoid damaging the conductor strands or leaving loose strands exposed.
- Operate the Correct Lever: Open the corresponding spring lever before inserting or removing a conductor.
- Secure the Connection: Close the lever fully and check that each conductor is properly retained.
- Verify Contact Assignments: Confirm the internal connection arrangement and pole assignments from the applicable wiring diagram before connecting circuits.
- Observe Electrical Ratings: Keep the installation within the stated 250V voltage and 32A current ratings, accounting for conductor size and operating conditions.
- Maintain Temperature Limits: Use the terminal within its stated operating temperature range of -20°C to +80°C.
- Inspect Each Position: Check for incomplete insertion, damaged insulation, loose strands or improperly closed levers.
- Provide Suitable Enclosure Protection: Install the terminal in an enclosure appropriate for the electrical and environmental conditions.
- Test Before Energising: Carry out suitable continuity and electrical checks after completing the connections and before restoring power.
