SPIDER Automation PCT-SPL-42 4:2 Pole Spring-Lever Wire Connector | Modified PA66 Multi-Conductor Terminal Block
Description
The SPIDER Automation PCT-SPL-42 4:2 Pole Wire Connector Terminal Block is a specialised spring-lever connector designed to create a two-wire connection from two pairs of conductor connections. Its 4:2 arrangement supports organised conductor joining in electrical distribution boxes, junction boxes, control cabinets and equipment wiring assemblies.
The terminal uses a spring-lever locking mechanism with operating levers for conductor insertion and release. Its insulating body is manufactured from modified PA66 nylon, while the contact components are stainless steel. This compact construction supports structured wiring in installations where multiple conductors need to be consolidated into a two-wire connection arrangement.
The PCT-SPL-42 supports solid conductors from 0.08–2.5mm² and stranded conductors from 0.08–4.0mm². Its stated rated current is 32A, and its operating temperature range is -20°C to +80°C. The rated-voltage entry requires clarification before a definitive voltage specification can be assigned.
Key Features

- Compact Connection Design: Helps consolidate multiple conductor connections within a compact terminal assembly.
- Multiple Colour Options: Available in blue, grey and orange versions.
4:2 Terminal Configuration & Connection Mechanism
The PCT-SPL-42 is designed around a four-to-two conductor connection arrangement. It allows two pairs of conductor connections to be combined into a two-wire connection arrangement. This configuration is useful where separate conductor pairs need to be consolidated through a dedicated terminal connector.
The spring-lever mechanism controls conductor retention. Operate the corresponding lever, insert the prepared conductor into its designated connection position and close the lever to engage the spring clamp. The precise internal contact mapping should be checked against the manufacturer’s wiring diagram before connecting conductors, particularly where different circuits or supply paths are involved.
Housing & Contact Construction
The terminal features a modified PA66 nylon housing that forms the insulating body around the connection assembly. Its contact components are identified as stainless steel. Operating levers provide access to the spring-clamping mechanism for conductor insertion and release.
The compact construction supports organised wiring in electrical enclosures and equipment assemblies. The specified operating temperature range is -20°C to +80°C.
Electrical & Conductor Compatibility
The connector accommodates two conductor types with separate cross-section ranges: 0.08–2.5mm² for solid conductors and 0.08–4.0mm² for stranded conductors. Its stated rated current is 32A.
Select conductor sizes according to the circuit load, conductor type and installation conditions. The stated current rating should not be assumed to apply to every supported conductor size under all operating conditions. Confirm the rated operating voltage and impulse withstand rating from the manufacturer’s technical documentation before selecting the terminal for a particular circuit.

Connection & Operating Recommendations
- Isolate the Electrical Supply: Disconnect power and verify that the circuit is de-energised before making or modifying connections.
- Confirm the 4:2 Wiring Arrangement: Identify the intended conductor pairs and verify their corresponding terminal positions against the manufacturer’s connection diagram.
- Select Compatible Conductors: Use solid conductors within 0.08–2.5mm² or stranded conductors within 0.08–4.0mm².
- Prepare Conductor Ends: Strip insulation carefully without damaging the conductor or leaving loose strands exposed.
- Operate the Appropriate Lever: Open the corresponding spring lever before inserting or removing a conductor.
- Insert Conductors Fully: Position each conductor correctly in its designated connection point before closing the lever.
- Check Conductor Retention: Verify that each conductor is firmly held and that no loose strands remain exposed.
- Observe Current Rating: Keep the installation within the stated 32A rating while accounting for conductor size and operating conditions.
- Verify Voltage Suitability: Confirm the rated operating voltage and impulse voltage from the manufacturer’s technical documentation before use.
- Maintain Temperature Limits: Operate the terminal within its stated -20°C to +80°C temperature range.
- Inspect Before Energising: Check the completed connections and perform suitable continuity and electrical tests before restoring power.
