FAQs
Install the CA4-04MK as a front-mounted auxiliary block on compatible AF09–AF16 contactors. Use the Push-In Spring terminals to connect each NC contact with a single push; ensure the wiring gauge matches 0.5–2.5 mm² for flexible conductors or 18–14 AWG rigid conductors as specified. Verify the orientation and mounting clips align with the carrier, then recheck all connections for secure, vibration-resistant operation.
The auxiliary circuit is rated for 690 V insulation with a rated frequency of 50/60 Hz. Conventional free-air thermal current is 16 A, and rated operational current for AC-15 is 2 A at 500 V, 2 A at 690 V; DC-13 ranges from 0.55–6 A depending on voltage. These ratings support reliable signaling while protecting control circuits in typical industrial environments.
Yes. The CA4-04MK complies with IEC/EN 60947-5-1, UL 60947-5-1, and CSA standards. It carries CE and UKCA markings, supports IP20 protection on auxiliary terminals, and aligns with RoHS/REACH requirements. This makes it suitable for global deployment in control cabinets and machine control systems.
The block measures 43 mm in width, 39.5 mm in depth, and 45 mm in height, with a net weight of 0.05 kg. This compact footprint helps maximize packing density in crowded control panels and enables multiple blocks to be installed side-by-side without crowding bus bars or wiring channels.
Push-In Spring terminals provide faster, tool-free wiring and more reliable connections by reducing looseness and vibration-induced faults. This translates to shorter installation times, lower labor costs, fewer field failures, and easier maintenance in high-demand environments such as automated conveyors and process lines.
