Terminal block Schelinger A18-MDB-215 — 30 poles, 2x15 arrangement (11×5.3 mm + 2×7.5 mm + 2×9.1 mm)

Schelinger A18-MDB-215 — 30 poles, 2x15 arrangement (11×5.3 mm + 2×7.5 mm + 2×9.1 mm) is a terminal block designed for organized connection of multiple conductors in control cabinets and automation panels. It groups thirty connection points into two parallel rows of fifteen positions each, combining different terminal sizes to accept a range of conductor cross-sections for signal distribution and low-voltage power wiring. The mixed-contact layout supports compact multi-circuit installations where both small and larger conductors are needed in a single assembly.

Advantages

The terminal block offers a compact 2×15 layout that maximizes connection density while keeping individual circuit access straightforward. By providing eleven smaller terminals alongside two medium and two larger terminals, it accommodates varied conductor sizes without requiring multiple separate blocks. The design supports neat DIN-rail or panel mounting and helps reduce wiring complexity in control cabinets by consolidating multiple circuits in a single modular component.

Suitable for

• Control cabinet wiring and distribution of signals
• Automation panel connections with mixed conductor sizes
• Electrical junctions requiring compact, multi-circuit terminal arrangement
• Industrial machine wiring where space-saving terminal solutions are needed

Key specifications

• Number of poles: 30 arranged as 2×15 positions
• Terminal sizes: eleven 5.3 mm contacts, two 7.5 mm contacts, two 9.1 mm contacts
• Mounting: suitable for DIN-rail or panel mounting
• Application: signal and low-voltage power distribution in control and automation equipment
• Form factor: mixed-size terminals in a compact modular housing

How to use

Install the terminal block onto the appropriate rail or secure it to the panel following the mounting requirements of the installation. Strip conductors to the recommended lengths for the respective terminal sizes and insert each conductor into the matching contact point, ensuring correct seating before tightening the terminal screws. Use the smaller 5.3 mm terminals for fine or signal wires and the 7.5 mm and 9.1 mm terminals for larger conductors or where higher current capacity is needed. Maintain proper labeling for each position to simplify maintenance and future modifications.

Usage recommendations

Check conductor cross-sections and torque specifications before final tightening, and ensure that insulation stripping length matches the terminal depth. For mixed-circuit applications, group similar circuits and clearly mark each row or pole to prevent wiring errors during installation and service.
