FAQs
Yes. CA4-04NK is a four-pole auxiliary block designed for NF-series contactors and their corresponding front-mounting interfaces. It uses Push-In Spring terminals for quick, secure terminations and aligns with standard 4-pole configurations commonly used in NF40/NFZ40 family assemblies, simplifying panel layouts and retrofit work.
The block provides four NC signals with a 690 V auxiliary circuit rating, operates at 50/60 Hz, and offers IP20 protection. It has a conventional thermal current Ith of 16 A at 40 °C, with AC-15 up to 2 A at various voltages and DC-13 up to 6 A (or lower depending on voltage). It supports up to 1200 cycles/hour (AC-15) and 900 cycles/hour (DC-13).
This block excels in motor-control panels, interlock signaling, and safety circuits where four NC signals are needed for NF-series contactors. It’s ideal for start/stop interlocks, machine-state signaling, and panel diagnostics in manufacturing lines, conveyors, and processing equipment.
CA4-04NK carries IEC/EN 60947-5-1, UL 60947-5-1, and CSA C22.2 No. 60947-5-1-14 certifications. RoHS and REACH declarations are provided, supporting global deployments and compliance in regulated markets while facilitating regulatory approvals and audits.
The Push-In Spring terminals and front-mounted design simplify wiring, reducing installation time and field errors. Fewer mis-wires translate to lower commissioning time, faster spare-parts strategy, and reduced downtime during maintenance or replacements, delivering a measurable reduction in total cost of ownership over the equipment’s life cycle.
