Distribution block Simet SIMBLOCK SUB 160 (81653002) — universal Al/Cu, gray

The Simet SIMBLOCK SUB 160 distribution block is a universal connector for aluminium and copper conductors designed for safe power distribution and branching. Its grey housing and compact form factor make it suitable for integration into switchgear, busbar systems and junction boxes where reliable conductor transition and secure clamping are required. The device supports mixed-metal connections and is intended for installations that require durable electrical continuity between Al and Cu cables.

Advantages

The SIMBLOCK SUB 160 provides a single-point solution for connecting aluminium and copper conductors without the need for separate adapters, reducing installation complexity. Its construction ensures stable mechanical clamping and low contact resistance, which contributes to predictable electrical performance. The grey insulating body protects conductive parts and helps organize wiring within confined electrical enclosures.

Suitable for

• Industrial and residential distribution boards and switchgear
• Busbar systems that require transition between Al and Cu conductors
• Junction boxes and cable branch points in power distribution circuits
• Applications demanding secure clamping and reliable electrical continuity

When it may not be suitable

The SIMBLOCK SUB 160 is intended for use with aluminium and copper conductors; it may not be suitable for specialized conductor types or unconventional conductor geometries that fall outside the manufacturer's specified range. It is also not a substitute for circuit protection devices and should not be used where overcurrent or fault protection is required without appropriate protective components in the circuit.

Key specifications

• Connector type: distribution block for mixed Al/Cu conductors
• Material: conductive contacts suitable for aluminium and copper; insulated housing in grey
• Application: power distribution and branching for Al and Cu cables
• Mounting: designed for integration in switchgear, busbar systems and junction boxes
• Electrical function: provides secure clamping and low-contact-resistance connections

How to use

Install the SIMBLOCK SUB 160 inside the electrical enclosure or onto the designated mounting rail according to the installation space available. Prepare conductor ends by stripping insulation to the appropriate length, ensure conductors are clean and free of oxidation, and insert aluminium and copper conductors into the respective ports. Tighten clamping screws to the torque values recommended by the connector manufacturer or by an installation standard, taking care to avoid over- or under-tightening. After installation, verify mechanical stability and measure contact continuity and resistance as part of commissioning.

What to consider before purchase

• Compatibility with conductor cross-sections and conductor types used in your installation
• Required mounting space and integration into switchgear or junction boxes
• Installation torque requirements and whether torque control tools will be used
• Compliance with applicable local electrical standards for mixed-metal connections

Usage recommendations

Use anti-oxidation treatment or jointing procedures recommended for aluminium-copper connections where required by local standards, and follow correct torque values and periodic inspection schedules to maintain long-term electrical and mechanical reliability.
