39990701 | SOCOMEC Auxiliary Contact Block 1NO

Description

Product Overview

The SOCOMEC Auxiliary Contact Block 1NO is engineered as a high‑reliability, single‑pole terminal block that fits seamlessly into a wide range of industrial electrical assemblies. Constructed from a copper‑alloy base with a nickel‑plated finish, the block offers excellent conductivity and resistance to corrosion, ensuring long‑term performance even in harsh environments. Its compact footprint—measuring just 1.3 x 1.05 x 0.4 inches—allows designers to maximize panel density without sacrificing accessibility. The block features a screw‑type clamping mechanism that secures wire conductors firmly, reducing the risk of loosening under vibration. With a rated current of up to 10 A and a voltage rating of 250 V AC, it meets the demanding standards of IEC 60947‑1 and UL 508A. The product is supplied in a single‑unit package, making inventory management straightforward for distributors and end‑users alike.

Usage

This auxiliary contact block is ideally suited for control panels, programmable logic controllers (PLCs), motor starters, and safety interlock circuits where a single auxiliary contact is required. Its robust design tolerates temperature ranges from –25 °C to +85 °C, making it appropriate for both indoor automation systems and outdoor installations exposed to seasonal fluctuations. The block’s straightforward wiring—simply strip the wire, insert it into the terminal, and tighten the screw—facilitates rapid assembly and reduces the potential for wiring errors. Engineers often employ the 1NO variant in applications such as signal indication, status monitoring, and relay interfacing, where a normally‑open contact must close upon activation of a primary device. The compact size also enables its use in space‑constrained enclosures, such as compact motor control centers or distributed control units.

FAQ

What wire gauge sizes are compatible with this contact block?

The block accepts solid or stranded conductors ranging from 22 AWG to 12 AWG. For optimal performance, ensure the wire is stripped to the recommended length and fully seated before tightening the screw.

Can this block be used in hazardous locations?

While the block itself meets standard industrial electrical requirements, it is not intrinsically rated for explosive atmospheres. For hazardous locations, pair the block with an appropriately certified enclosure or barrier that complies with ATEX or IECEx standards.

Is the block compatible with both DIN rail and panel mounting?

Yes. The block includes mounting tabs that allow secure attachment to a DIN rail, as well as optional panel‑mount brackets for direct installation onto a control panel surface.

What is the recommended torque for the screw terminals?

Socomec advises a tightening torque of 0.5 Nm (4.4 in‑lb) for the screw terminals. This torque ensures a reliable connection without damaging the conductor or the terminal body.

How does Socomec handle warranty and replacement?

All SOCOMEC Auxiliary Contact Blocks are covered by a two‑year limited warranty against manufacturing defects. If a defect is identified, contact our support team with the product serial number and purchase documentation to arrange a replacement.
