FAQs
Install the 4-pole block as a front-mounted accessory on the AF series contactor range. Use screw terminals compatible with ring tongue ferrules, tighten to 1.2 N·m for the auxiliary circuit, and connect the NO contacts to the control signaling circuit rated up to 690 V and 50/60 Hz. Verify correct NONC configuration and perform a functional test before commissioning.
The auxiliary circuit is rated up to 690 V with 50/60 Hz operation. Rated operational currents for AC-15 vary by voltage (up to 4 A at common industrial voltages) and DC-13 ratings include several voltages (for example 24 V up to 125 V and currents around 0.55–6 A depending on voltage). Short-time withstand and insulation ratings meet IEC/EN 60947-5-1 standards.
This auxiliary block is designed for AF09B, AF09ZB, AF12B, AF12ZB, AF16B, AF16ZB, AF26B, AF26ZB, AF30B, AF30ZB, AF38B, and AF38ZB contactors. The 4 NO configuration supports signaling across the full AF range, enabling consistent interlocks and status feedback in panel designs.
It conforms to IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10. Additional declarations include CE and UKCA, RoHS and REACH compliance, and WEEE B2B classification. These certifications support regulatory compliance, sustainability goals, and safer, traceable product usage in industrial environments.
Product net width is 45 mm, depth 39.8 mm, and height 43 mm, with a net weight of 0.05 kg. The front-mounted design with screw terminals for ring tongue ferrules enables fast wiring and secure connections in compact 45 mm-wide enclosures, reducing panel depth and enabling tighter layouts in control cabinets.
