Rittal electrical complete connector 2 model 2500.620, conductor cross-section 0.25–1.5 mm², black, pack of 5

Rittal 2500.620 is a compact complete electrical connector designed for feed-in and through-wiring in control cabinets and panel installations. The two-pole connector accepts conductor cross-sections from 0.25 to 1.5 mm², is supplied in black and is sold in packs of five. It is intended for applications where small form factor, clear polarity and reliable electrical contact are required for signal and low-power circuits.

Advantages

This connector provides a ready-to-install solution that reduces assembly time compared with loose components. Its two-pole design and defined conductor range simplify wiring tasks and help maintain consistent contact quality across multiple terminations. The compact dimensions allow space-saving placement inside control enclosures and panels while the black housing offers visual consistency with typical industrial equipment.

Suitable for

• Feed-in and through-wiring of signal and low-power circuits in control cabinets
• Panel wiring where compact two-pole connections are required
• Maintenance and retrofit work that benefits from preassembled connector packs
• Applications with conductors sized between 0.25 and 1.5 mm²

When it may not be suitable

This connector is designed for low-power and signal wiring; it is not intended for high-current power distribution or applications requiring larger conductor cross-sections than the specified 0.25–1.5 mm² range. Environments requiring special protection ratings (for example, high ingress protection, corrosive atmospheres, or extreme temperatures) may require connectors with specific sealing, material or certification features that this standard housing does not provide.

Key specifications

• Poles: 2
• Acceptable conductor cross-section: 0.25–1.5 mm²
• Colour: black
• Pack quantity: 5 pieces
• Typical use: feed-in and through-wiring for control cabinets and panels

How to use

Strip conductors to the manufacturer-recommended length, insert each conductor into the corresponding pole of the connector and secure according to the connector’s termination method (for example, screw or push-in as applicable). Mount the connector in the panel or wiring channel in the required orientation and verify correct polarity and tightness of each connection. After installation, perform a basic continuity and insulation check to confirm reliable contact and correct wiring.

What to consider before purchase

• Verify that conductor sizes to be used fall within the 0.25–1.5 mm² range
• Confirm that a two-pole connector meets the circuit and polarity requirements of your application
• Assess environmental and mechanical requirements (vibration, temperature, ingress protection) to ensure the connector’s housing and materials are suitable
• Ensure the pack quantity of five meets your project needs or ordering strategy

Usage recommendations

Use the connector for signal-level and control wiring inside electrical cabinets and panels where compact, consistent connections are needed. Follow standard installation practices: correct conductor preparation, secure termination, and post-installation electrical checks to ensure reliable operation.
