Weidmüller 1003170000 HDC HQ 4/2 MC Male Insert Explained

The Weidmüller 1003170000 HDC HQ 4/2 MC is a compact hybrid insert created for industrial applications where power and auxiliary circuits need to coexist in one rugged connector interface. In modern automation design, compactness is not just convenient. It often determines whether a cabinet layout, machine module, or field connection strategy remains practical over time. The Weidmüller HDC HQ 4/2 MC is designed precisely for that kind of space-conscious engineering.

This product is the male insert version in the HQ hybrid family. It uses a crimp connection, carries a general specification of 690 V and 40 A, and is described as having 6 poles within the HQ installation size. Product documentation and related hybrid data also identify the configuration as 4/2 (+PE), reflecting its mixed-contact design for combined duties inside one insert body.

What Makes the Weidmüller 1003170000 Different

The most distinctive feature of the Weidmüller 1003170000 HDC HQ 4/2 MC male insert is that it combines compactness with functional versatility. In industrial connector selection, engineers are often forced to balance available space against electrical requirements. The HQ format helps address that trade-off by providing a relatively compact installation size without abandoning the durability associated with heavy-duty connector platforms.

The “MC” designation identifies the insert as the male mating side. Together with the corresponding female version, it forms part of a connector solution that can carry both higher-power and auxiliary-level connections through a single structured interface. That makes it particularly useful in modular equipment, servo-related assemblies, compact motor connections, and machinery that needs dependable yet efficient connection architecture.

Electrical and Mechanical Characteristics

The Weidmüller HDC HQ 4/2 MC is defined as an HDC insert, male, 690 V, 40 A, with crimp connection, installation size HQ. Supporting technical references identify the hybrid arrangement as 4/2 (+PE) with a 40/10 A current profile and 690 / 250 V rated voltage context. This mixed specification is what makes the insert useful in systems where one connection interface must support more than one electrical duty.

Dimensionally, the product is listed with approximately 41.6 mm depth, 48 mm height, and 22.4 mm width, with a net weight of around 20.24 g. Those figures matter because connector selection is never purely electrical. Fit, spacing, routing clearance, and enclosure compatibility are just as important in real installations.

The insert works with crimp contacts, which are not included with the insert body. This allows the user to choose the correct contact elements based on conductor cross-section and application needs. In industrial practice, that flexibility is useful because it supports standardized connector bodies across different wiring requirements.

Why the HQ 4/2 MC Format Works Well in Industry

The Weidmüller 1003170000 HDC HQ 4/2 MC connector insert is particularly attractive in applications where every millimeter matters. Hybrid inserts reduce the number of separate connector interfaces, which can simplify installation, reduce panel congestion, and improve service access.

In machine building and industrial automation, fewer separate connectors often mean fewer potential failure points, simpler spare-parts logic, and more consistent assembly processes. That is why this type of insert is commonly considered for compact machine modules, decentralized equipment, handling systems, and equipment with both power and auxiliary connection needs.

Selection Considerations

The insert should always be selected as part of a full connector system. That means verifying the matching female insert, the appropriate HQ housing, and the correct contact elements. Engineers should also consider conductor size, current distribution across the hybrid layout, and the environmental requirements of the final installation.

FAQ

What is the Weidmüller 1003170000 HDC HQ 4/2 MC?

It is a male hybrid heavy-duty connector insert in the HQ series with a crimp connection and a mixed 4/2 (+PE) layout.

What are the main ratings of the Weidmüller HDC HQ 4/2 MC?

The product is generally specified at 690 V and 40 A, with hybrid technical references showing 40/10 A and 690 / 250 V according to contact grouping.

Is this insert male or female?

The Weidmüller 1003170000 is the male version. The FC version is the female counterpart.

Does this insert include contacts?

No. The insert body is typically supplied without crimp contacts, so the contact elements are chosen separately to suit the wiring specification.

Why choose a hybrid insert like the HDC HQ 4/2 MC?

It allows power and auxiliary circuits to be combined in one compact connector interface, which can simplify layout and reduce installation complexity.

Where is the Weidmüller 1003170000 commonly used?

It is commonly used in automation systems, machine modules, compact industrial equipment, and applications where connector density and ruggedness are both important.
