Key specifications

• Compatible with aluminum and copper conductors
• Screw-type connection mechanism
• Designed for standard rail mounting
• High-strength insulating housing
• Suitable for industrial and residential use

How to use

To install the Simet STB 185, first ensure that the power supply to the circuit is completely disconnected. Mount the terminal block onto the standard DIN rail until it clicks into place. Strip the insulation from the conductor to the recommended length, ensuring the wire is clean and free of oxidation. Insert the conductor into the terminal opening and tighten the screw to the specified torque to ensure a secure connection. Verify that the wire is firmly held in place before restoring power to the system.

What to consider before purchase

• Verify the cross-section of your conductors matches the terminal capacity
• Ensure the mounting rail type is compatible with the block design
• Confirm the current and voltage requirements of your installation

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended torque settings to prevent damage to the conductors or the terminal block itself.
