Product information

Description

The Simet STB 50-3 SIMBLOCK is a professional-grade threaded rail terminal block engineered for the secure termination of both aluminum and copper conductors. Designed for integration into electrical distribution panels, this blue terminal block provides high mechanical stability and consistent electrical conductivity. It is a reliable component for managing power distribution in industrial and residential electrical systems, ensuring a firm connection on standard DIN rails.

Advantages

This terminal block offers exceptional versatility by supporting both aluminum and copper wiring, which simplifies inventory management and installation processes.

DIN rail mounted electrical installations

When it may not be suitable

This terminal block is not intended for use with conductors outside of the specified cross-section range or for applications requiring specialized environmental protection against extreme moisture or corrosive gases. It should not be used in circuits exceeding the rated voltage or current capacity specified for this component.

Key specifications

Conductor compatibility: Aluminum and Copper
Mounting type: DIN rail
Color: Blue
Connection type: Threaded

How to use

To install the Simet STB 50-3, snap the terminal block onto a standard DIN rail until it clicks into place. Strip the insulation from the end of your aluminum or copper conductor to the required length. Insert the conductor into the terminal opening and tighten the screw using an appropriate screwdriver to ensure a secure mechanical connection. Verify that the wire is firmly held and cannot be pulled out before energizing the circuit.

What to consider before purchase

Ensure the conductor cross-section matches the terminal capacity
Verify the available space on the DIN rail within the enclosure
Confirm compatibility with the specific wire material being used

Usage recommendations

Always ensure that the power supply is disconnected before performing any installation or maintenance work on electrical terminals. Use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended torque settings to prevent damage to the conductors.
