When it may not be suitable

This terminal block is designed for standard DIN rail mounting and may not be suitable for applications requiring direct chassis mounting or specialized hazardous area certifications not specified for this model. It is intended for use with copper conductors within the specified cross-section range and should not be used for high-power applications exceeding its rated current or voltage limits.

Key specifications

• Conductor cross-section: 4mm²
• Rated current: 32A
• Rated voltage: 800V
• Connection type: 2-conductor
• Mounting type: DIN rail
• Color: Dark gray

How to use

To install the terminal block, snap it onto a standard DIN rail until it clicks securely into place. Strip the insulation from your conductors to the appropriate length and insert them into the terminal points. Tighten the screws to the recommended torque to ensure a firm mechanical and electrical connection. Ensure that all wiring complies with local electrical codes and that the total load does not exceed the rated capacity of the terminal block.

What to consider before purchase

• Verify that the 4mm² cross-section is compatible with your wire gauge requirements.
• Ensure the DIN rail type in your enclosure matches the mounting requirements of the terminal block.
• Check that the 32A and 800V ratings are sufficient for your specific circuit load.
• Confirm the total number of terminal blocks needed for your wiring layout.

Usage recommendations

Always ensure that power is disconnected before performing any wiring or maintenance on the terminal block. Use appropriate tools for tightening connections to prevent damage to the screw terminals and ensure optimal contact pressure.
