CQ4M 03/2 ILME Male insert 3+2p +PE 40 amp crimp Size 21.21

Why Choose the ILME CQ4M 03/2 Male Insert?

The ILME CQ4M 03/2 is a compact male industrial connector insert from the ILME CQ series, combining 3 main poles, 2 auxiliary poles and protective earth (3+2P+PE) within the space-saving size 21.21 format. Designed for crimp termination, it provides high-current power connections alongside lower-current auxiliary circuits in one compact heavy-duty connector interface.

The three main contacts are rated at 40 A, 400 V, while the two auxiliary contacts are rated at 10 A, 250 V. This mixed-contact arrangement makes the CQ4M 03/2 particularly useful for machinery and automation applications requiring power and auxiliary control, signalling or monitoring circuits through the same detachable connector.

The insert is supplied without crimp contacts, allowing the appropriate male contacts to be selected according to conductor size. Compatible 40 A contacts accommodate conductors from 1.5–6 mm², while the compact polycarbonate insert provides durable insulation and reliable service in demanding industrial environments.

Key Advantages

• Combines 3 high-current poles + 2 auxiliary poles + PE in one compact insert.
• Main contacts rated at 40 A, 400 V for industrial power connections.
• Auxiliary contacts rated at 10 A, 250 V for control and signalling circuits.
• Compact size 21.21 format saves installation space.
• Crimp connection provides reliable, repeatable conductor termination.
• Separate crimp contacts allow conductor sizes to be matched precisely to the application.

Compact Power and Auxiliary Connectivity in One Insert

The ILME CQ4M 03/2 is designed for applications where higher-current power circuits and lower-current auxiliary connections need to pass through the same compact connector. Its three 40 A main poles can handle demanding power circuits, while two dedicated 10 A auxiliary poles provide connections for controls, sensors, interlocks or signalling without requiring a separate connector.

Crimp termination provides a reliable connection method for machinery subject to vibration and repeated servicing. The 40 A male contacts are available for 1.5 mm², 2.5 mm², 4 mm² and 6 mm² conductors and are ordered separately, allowing the connector assembly to be configured for the exact cable requirements of the installation.

Typical Applications

• Industrial machinery and machine building.
• Motor and drive connections with auxiliary circuits.
• Factory automation and production equipment.
• Robotics and automated machinery.
• Compact power and control interfaces.
• Packaging and processing equipment.
• Conveyors and material handling systems.
• Industrial equipment requiring combined power, control and protective earth connectivity.
