FAQs
The block is designed for AF09B, AF09ZB, AF12B, AF12ZB, AF16B and AF16ZB contactors. This compatibility ensures plug-in mounting and consistent terminal spacing, simplifying panel design and reducing part proliferation in control systems.
The block provides 4 poles with 3 normally open and 1 normally closed contacts. The auxiliary circuit is rated up to 690 V with AC-15 and DC-13 operating currents suitable for a wide range of signaling and interlocking applications in industrial automation.
Yes. It conforms to IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10, with CE and UKCA declarations. This makes it appropriate for compliance-driven panel builds in global installations, including railway rolling stock applications referenced in the accompanying data sheet.
The front-mounted design with screw terminals for ring-tongue ferrules allows secure, repeatable terminations and faster wiring. The compact 45 x 39.8 x 43 mm footprint enables higher panel density, while the 1.2 N·m tightening torque ensures consistent connections and long-term reliability.
By standardizing signaling with a robust, field-installable accessory, maintenance reduces due to fewer miswired connections and fewer recalibrations. The block’s durable materials, broad voltage range, and clear terminal layout contribute to lower downtime and a favorable return on investment in automation projects.
