CQ4M03 Ilme Male insert 3 pole and earth 40 amp crimp Size 21.21

Why Choose the ILME CQ4M03 Male Insert?

The ILME CQ4M03 is a compact 3-pole plus protective earth male connector insert designed for high-current heavy-duty industrial connections. Part of the ILME CQ series, it combines a 40 A, 400 V rating with crimp termination in the space-saving size 21.21 format.

The CQ4M03 is supplied without crimp contacts, allowing the appropriate ILME 40 A male contacts to be selected separately for the conductor size required. Compatible silver-plated CXMA crimp contacts are available for conductors from 1.5–10 mm², providing flexibility for industrial power wiring while maintaining a secure and repeatable termination method.

With a 6 kV rated impulse withstand voltage, pollution degree 3 and mechanical durability of at least 500 mating cycles, the CQ4M03 provides dependable connectivity for industrial machinery and automation equipment. When fitted into a suitable ILME size 21.21 enclosure, the connector assembly can provide high levels of ingress protection for demanding operating environments.

Reliable High-Current Connections in a Compact Format

Industrial machinery often requires detachable power connections capable of carrying substantial current while using minimal installation space. The ILME CQ4M03 combines three power contacts with a dedicated protective-earth connection in the compact size 21.21 format, providing a practical interface for machinery, motors and industrial power distribution.

The separate crimp-contact system allows the appropriate contact to be selected for conductors from 1.5–10 mm² and securely terminated before insertion into the connector body. When paired with the corresponding female insert and installed in a compatible ILME size 21.21 enclosure, the CQ4M03 forms part of a robust heavy-duty connector system for reliable equipment installation and servicing.

Typical Applications

• Industrial machinery and production equipment.
• Three-phase motor and machine connections.
• Factory automation systems.
• Electrical control panels and cabinets.
• Conveyor and material handling equipment.
• Compact high-current detachable power interfaces.
