Distribution block - tap-off SCB 25-2 Al/Cu 80120 SIMBLOCK black 81505007

Distribution block – branch, a compact solution for demanding installations

The SCB 25-2 distribution block is a single-pole device from the SIMBLOCK series, designed for safe and efficient connection of aluminum (Al) and copper (Cu) wires in industrial installations, commercial buildings and modern low-voltage switchboards. Designed to operate at a rated voltage of up to 1000V AC/DC, it is a reliable solution for professionals and end users.

Construction and application

The SCB 25-2 block features a well-thought-out design that ensures stable and durable electrical connections. Two wire fixing screws guarantee even pressure on the conductor, minimizing the risk of loosening connections even under vibration or temperature changes. The ability to handle aluminum and copper wires with a cross-section of 2.5–25 mm² (solid) and 1.5–16 mm² (stranded with ferrule) increases the product's versatility.

Compact dimensions – only about 41 mm wide – allow for efficient use of space on the TS 35 mounting rail. This is particularly important in modern switchboards, where every millimeter counts. The rated current of 152A/100A ensures stable operation under high loads. The housing made of thermoplastic material with a flammability class of UL94 V0 ensures safe use and protects against accidental contact with live parts. Mounting is quick and easy on a standard DIN TS 35 rail.

Key features and benefits

• Versatility: Support for aluminum and copper wires eliminates the need to use different distribution blocks for different types of wires.
• Safety: Two fixing screws ensure a stable connection and minimize the risk of wire loosening, and the UL94 V0 material housing protects against electric shock and prevents the spread of fire.
• Compactness: The narrow design saves space in the switchboard, which is particularly important in limited mounting spaces.
• High reliability: Durable materials and precise workmanship guarantee long-lasting and trouble-free operation of the device.
• Easy installation: Quick mounting on the DIN TS 35 rail shortens installation time and reduces labor costs.
