FAQs
The CA4-40EK auxiliary block is specified for use with AF09 through AF96 contactors, providing four normally open signaling contacts. This ensures consistent mechanical and electrical interface, simplifying replacement and upgrades in existing installations without re-wiring cabinets.
Rated auxiliary circuit voltage is up to 690 V with a frequency of 50/60 Hz. For AC-15 operation, typical currents range from 2 A at higher voltages down to 6 A at low-voltage options; DC-13 currents vary by voltage (example: 6 A at 24 V up to 0.1 A at 600 V). Short-time withstand current is 140 A (0.1 s) and 100 A (1 s).
Push-In Spring terminals allow a single push to secure conductors, reducing wiring time and increasing connection reliability. They support both flexible and rigid conductors within specified cross-sections, improving field installation speed and consistency across panels.
The block complies with IEC/EN 60947-5-1, UL 60947-5-1, and CSA C22.2 No. 60947-5-1-14. These certifications support global deployment, safety validation, and alignment with regional electrical codes for control components.
The unit has a compact 43 mm width, 39.5 mm depth, and 45 mm height with IP20 protection in the auxiliary terminals. Its slim form and front-mounting design make it suitable for retrofit projects in existing AF contactor assemblies, minimizing panel intrusion and facilitating quick upgrades.
