Why Choose the Ilme CQ4F03 Female Insert?

The Ilme CQ4F03 is a compact 3-pole plus earth female multipole connector insert designed for high-current electrical connections in industrial machinery, automation equipment and control systems. Part of the Ilme CQ4 series, it combines a compact size 21.21 format with crimp termination and a rated current of 40 A.

The CQ4F03 uses female crimp contacts, providing a secure, vibration-resistant connection when assembled with the appropriate Ilme contacts and correctly crimped conductors. Crimp termination is particularly well suited to production wiring and industrial equipment where consistent electrical and mechanical performance is important.

With 3 poles plus protective earth and a 40 A current rating, the CQ4F03 provides substantial power-handling capability within a compact connector footprint. When paired with the corresponding male insert and a suitable Ilme size 21.21 hood or housing, it forms a durable detachable connection for motors, machinery and industrial power circuits.
