Why Choose the Ilme CKF03RY Female Insert?

The Ilme CKF03RY is a high-temperature female industrial connector insert with 3 poles plus protective earth (3P+PE), designed for reliable power and control connections in demanding machinery and automation applications. Part of the Ilme CK RY series, it combines screw-terminal wiring with silver-plated female contacts and a compact size 21.21 format.

The CKF03RY is rated at 10 A and 230/400 V, with a rated impulse withstand voltage of 4 kV and pollution degree 3. Its screw terminals accept conductors from 0.75–2.5 mm², equivalent to AWG 18–14, providing a straightforward and dependable termination method for industrial wiring.

Unlike standard CK inserts, the CKF03RY is specifically engineered for applications up to 180 °C. Its PPS insulating body and turned silver-plated contacts make it suitable for high-temperature industrial installations while maintaining the compact dimensions and modular compatibility of the Ilme size 21.21 connector system.
