FAQs
CAT4-11MRT is designed for AF09B, AF09ZB, AF12B, AF12ZB, AF16B and AF16ZB contactors. The front-mounted A1/A2 coil terminals and ring-tongue-compatible screw terminals streamline wiring in tight panels, reducing miswiring risk. Always verify dimensions against your enclosure and check that the 2P form factor aligns with your control scheme.
The unit provides a 690 V auxiliary circuit rating with 50/60 Hz operation for both auxiliary and control circuits. It offers 1 NO and 1 NC contact, I_th of 16 A, and maximum switching frequencies of AC-15 up to 1200 cycles/hour and DC-13 up to 900 cycles/hour, supporting reliable signaling in standard automation tasks.
Yes. With IP20 protection, compact 45 × 31.6 × 43 mm dimensions, and RoHS/REACH compliance, the CAT4-11MRT is well-suited for industrial panels and rolling stock control applications where space and regulatory compliance matter. Its 2P design and dual NO/NC contacts enable versatile signaling and feedback in automated systems.
The CAT4-11MRT meets IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10, ensuring global compatibility and safe integration into electrical control panels. This compliance supports safer installations, easier cross-border procurement, and adherence to electrical safety and performance requirements in industrial environments.
By using ring-tongue terminals and a front-mounted design, wiring time is reduced and connection reliability is improved, lowering maintenance events and downtime. Clear data sheets, CAD drawings, and installation instructions streamline engineering validation, while compatibility with AF09–AF16 variants simplifies inventory, reducing procurement complexity and total cost of ownership.
