The CA4-22MRT provides four poles with two normally open and two normally closed auxiliary contacts, enabling robust signaling and safe interlocking in control circuits. The 4P design reduces the number of separate devices in a control panel, lowering wiring complexity and improving diagnostic clarity in conveyor and machine automation applications. Front-mounted screw terminals designed for ring tongue ferrules with a conic washer deliver quick, vibration-resistant terminations and dependable long-term performance. This installation approach minimizes wiring time on the shop floor and reduces maintenance calls due to loose connections in high-vibration environments such as packaging lines and mills. Rated for auxiliary circuits up to 690 V and 50/60 Hz, with I_th of 16 A at 40°C and individual Ie ratings across voltages, it supports AF09–AF16 contactors and simplifies spare-part inventories. Built to IEC/EN 60947-5-1, UL 508 and CSA C22.2 No. 14-10, the block ensures regional compliance, IP20 protection, and a tightening torque of 1.2 N·m for reliable field installations. Its compact dimensions (45 mm width, 39.8 mm depth, 43 mm height) and light 0.05 kg weight ease panel layout, making it a practical accessory for automation projects, compatible with AF09B AF09ZB AF12B AF12ZB AF16B AF16ZB series contactors and supported by available data sheets and CAD drawings to accelerate design cycles.

FAQs
The CA4-22MRT is a front-mounted, four-pole auxiliary contact block designed to accompany ABB AF09B, AF09ZB, AF12B, AF12ZB, AF16B and AF16ZB contactors. It provides two normally open and two normally closed auxiliary contacts, and uses ring-tongue terminals for secure terminations. This compatibility minimizes wiring changes during panel modernization and maintains consistent signaling across the controller family.
The auxiliary circuit is rated for 690 V and 50/60 Hz, with a Conventional Free-air Thermal Current (I_th) of 16 A at 40°C. Rated Operational Current for AC-15 is up to 2 A at multiple voltages, and DC-13 up to 6 A at 24 V to 600 V ranges. It also offers a 6 kV impulse withstand voltage and a maximum mechanical switching frequency of 3600 cycles per hour.
Yes. The CA4-22MRT is referenced in data sheets for rolling stock motor control and protection, and it complies with IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10. It is designed for industrial control panels as well as rolling stock applications, offering robust signaling, high reliability, and broad regional certification to support global deployments.
The accessory uses screw terminals with ring-tongue ferrules and a conic washer for secure termination. Tightening torque for the auxiliary circuit is 1.2 N·m, with UL/CSA torque specified at 11 in·lb. The IP20 protection rating helps safeguard against dust ingress in typical industrial environments, while the compact 45 mm width and 43 mm height simplify panel fitment.
Using the CA4-22MRT reduces wiring complexity with a single 4P block, lowering panel assembly time and fault risk from loose connections. Its compatibility with AF09–AF16 family minimizes spare-parts inventory, while CE/UL/CSA certifications ease multi-region deployments. The compact form factor and lightweight design also support lean manufacturing and faster time-to-market for automation projects.
