Simet OTL50-3 Screw Terminal Block for AL/CU Conductors 1.5-50 mm2, TS 35 Rail, 1-Pole, 6 Connections, Blue

The Simet OTL50-3 is a professional 1-pole screw terminal block engineered for the secure and reliable connection of both aluminum and copper conductors. With a versatile capacity for wire cross-sections ranging from 1.5 to 50 mm2, this terminal block features 6 clamping points, making it an ideal choice for complex electrical distribution tasks. Designed for seamless integration into standard TS 35 DIN rail systems, it provides a robust solution for maintaining high electrical conductivity and long-term durability in demanding environments.

Advantages

This terminal block offers exceptional versatility by allowing the direct connection of aluminum and copper wires, which simplifies installation processes in mixed-material electrical systems. The robust screw-clamping mechanism ensures a high-pressure contact that minimizes resistance and prevents overheating, contributing to the overall safety and efficiency of the electrical circuit. Its compact 1-pole design with multiple connection points optimizes space within control cabinets and distribution boards, while the high-quality materials ensure resistance to mechanical stress and environmental factors.

Suitable for

• Industrial electrical distribution panels
• Commercial building wiring systems
• Power supply distribution for machinery
• Connecting aluminum and copper conductors in control cabinets

When it may not be suitable

This terminal block is not intended for use in environments with extreme vibration or high-corrosion conditions unless additional protective enclosures are utilized. It is also not suitable for conductors exceeding the specified 50 mm2 cross-section or for applications requiring specialized high-current busbar connections that fall outside the standard TS 35 rail mounting configuration.

Key specifications

• Conductor range: 1.5 - 50 mm2
• Material compatibility: Aluminum and Copper
• Mounting type: TS 35 DIN rail
• Number of poles: 1
• Number of connection points: 6
• Color: Blue

How to use

To install the Simet OTL50-3, first ensure that the power supply to the circuit is completely disconnected. Snap the terminal block onto a standard TS 35 DIN rail until it clicks securely into place. Strip the insulation from the ends of the aluminum or copper conductors according to the required length. Insert the conductors into the designated clamping points and tighten the screws firmly to ensure a secure mechanical and electrical connection. Verify that the wires are held tightly and cannot be pulled out before restoring power to the system.

What to consider before purchase

• Verify the cross-section of your conductors falls within the 1.5-50 mm2 range.
• Ensure your installation environment supports TS 35 rail mounting.
• Confirm the total number of connections required for your specific circuit layout.
• Check local electrical regulations regarding the use of aluminum conductors in your specific application.

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended specifications to prevent damage to the conductors or the terminal block itself. Regularly inspect connections in high-load applications to ensure long-term stability.
