Terminal block ProBase 0024359 for electrical connections, 32A 450V, 5 conductors, for 0.2–4 mm²

ProBase 0024359 is a five-position terminal block designed for secure distribution and termination of electrical conductors. Rated for continuous operation at 32A and 450V, this connector accepts wire cross-sections from 0.2 to 4 mm² and provides reliable clamping for both solid and stranded conductors. Its compact form factor and straightforward screw-clamp terminals simplify wiring and maintenance in control panels, junction boxes and general electrical installations.

Advantages

The terminal block offers robust current and voltage ratings suitable for a wide range of low-voltage industrial and building installations. Its screw-clamp design ensures a stable electrical connection and easy retermination when circuits are modified. The five-position layout allows distribution across multiple conductors while maintaining clear separation between conductors. Materials and construction provide mechanical stability and consistent contact pressure, reducing the risk of loosening under normal operating conditions.

Suitable for

• Control panels and automation cabinets
• Junction boxes and distribution blocks
• General electrical installations in commercial and residential buildings
• Signal and low-voltage power distribution
• Maintenance and retrofit wiring tasks

Key specifications

• Number of positions: 5 conductors
• Rated current: 32 A
• Rated voltage: 450 V
• Accepted conductor cross-section: 0.2–4 mm²
• Compatible conductor types: solid and stranded conductors
• Termination method: screw-clamp connections
• Mounting: DIN-rail or panel mounting compatible (depending on installation configuration)

How to use

Prepare conductors by stripping insulation to the recommended length for secure insertion into the screw-clamp terminals. Insert each conductor fully into the corresponding terminal and tighten the screw to the torque recommended by installation standards to ensure reliable contact. Verify polarity and circuit layout before energizing. For multi-conductor distribution, use the five positions to organize input and outgoing conductors, keeping clear labeling to simplify future maintenance. Follow applicable electrical codes and safety procedures during installation and testing.

Usage recommendations

Ensure that conductor sizes remain within the specified 0.2–4 mm² range and that tightening torques follow local electrical standards. Regularly inspect terminal connections for signs of corrosion or loosening in environments subject to vibration or humidity. Use appropriate ferrules for fine-stranded wires when recommended to improve contact reliability.
