Terminal block Simet SCB 25-Cu 1-potential combined 100A for conductors 4×2.5–25 mm² gray

Simet SCB 25-Cu is a 1-potential combined terminal block designed for multi-conductor connections and grounding in electrical distribution systems. Rated for 100 A and accommodating four conductors with cross-sections from 2.5 to 25 mm², this gray modular unit is intended for DIN-rail mounting in electrical panels and switchboards. The design provides compact, space-saving connection of multiple conductors while ensuring reliable clamping and continuity for protective and functional earthing or common potential distribution.

Advantages

The SCB 25-Cu offers a high current rating with a broad conductor range, allowing use with both small and large cross-section conductors without the need for adapters. Its combined multi-wire terminal reduces wiring time and saves space on DIN rails compared with multiple single terminals. The modular housing and screw-clamp connection deliver robust mechanical retention and low-resistance electrical contact, suitable for industrial and building installations where dependable potential distribution is required.

Suitable for

• Grounding and protective earth distribution in control panels
• Common potential bus for power and signal circuits
• Connecting multiple conductors in industrial switchboards
• Space-saving multi-wire termination on DIN rails

Key specifications

• Current rating: 100 A
• Conductor capacity: 4 conductors, 2.5–25 mm² each
• Poles: 1 potential (combined multi-wire)
• Mounting: DIN-rail compatible modular housing
• Connection type: screw-clamp for secure conductor fixation
• Color: gray

How to use

Mount the SCB 25-Cu on a standard DIN rail inside the panel, ensure power is isolated before wiring, and strip conductor insulation to the recommended length for screw-clamp connections. Insert up to four conductors into the terminal opening and tighten the screw clamps to the manufacturer’s recommended torque to ensure reliable electrical contact and mechanical retention. Verify continuity and secure mounting after installation and restore power only after confirming correct wiring and clamp tightness.

Usage recommendations

Use appropriately sized ferrules or tinned ends for fine-stranded conductors to improve clamp reliability. Observe the rated current and conductor cross-section limits, and follow local electrical codes and torque specifications when installing the terminal block.
