DIN Rail Mount 20 Position Screw Terminal Block Distribution Module with 10 Channel Fuses

Description

Product Overview

The CZH-LABS DIN rail mount terminal block is engineered for high‑density wiring applications where space, reliability, and safety are paramount. Featuring a 20‑position layout, each terminal is capable of handling up to 30 A at 300 V, while the integrated fuse channels provide 10 A protection per circuit, ensuring that overloads are quickly isolated without compromising the rest of the system. Constructed from fire‑proof nylon for the DIN‑rail carrier, the module resists heat and flame, meeting stringent industrial safety standards. The terminal contacts are forged brass, delivering excellent conductivity and long‑term wear resistance, while the M3 steel screws are plated with chromium‑zinc for corrosion resistance and secure clamping. Wire ranges from 26 AWG to 10 AWG (4 mm²), with a 7.62 mm pitch that aligns with standard DIN‑rail spacing, making installation straightforward on 35 mm wide rails. The fuse holders accept D5 mm × L20 mm tube fuses, allowing quick replacement and minimal downtime during maintenance. Designed and manufactured in Taiwan using high‑quality materials, this block avoids the pitfalls of low‑cost, China‑origin carriers, delivering a robust solution for demanding industrial environments.

Usage

This terminal block excels in a variety of settings, from factory automation panels and motor control centers to renewable energy inverters and building management systems. Its compact 20‑position design enables dense circuit layouts, ideal for space‑constrained control cabinets where every millimeter counts. The built‑in fuse channels simplify wiring by eliminating the need for separate fuse holders, reducing both part count and assembly time. Electricians and system integrators will appreciate the clear labeling of each terminal position (01‑01, 02‑02, …, 10‑10) and the direct‑connect fuse positions (F1‑F1′, F2‑F2′, …, F10‑F10′), which streamline troubleshooting and future upgrades. The module’s robust construction makes it suitable for harsh environments, including high‑temperature factories, outdoor enclosures with limited ventilation, and applications subject to vibration or mechanical shock. Its fire‑proof carrier and brass contacts ensure reliable operation even under fault conditions, providing peace of mind for critical infrastructure where downtime is costly.
