FAQs
CAL4-11RT is designed to clip onto ABB AF09–AF38(Z)B..RT contactors and NFZB..RT relays, and can be mounted on either the left or right side of the carrier. The unit uses non-detachable screws with conic washers for fast, secure cable termination, and its compact form enables retrofits in crowded panels without sacrificing performance.
For AC-15 applications, CAL4-11RT supports up to 2 A at higher voltages (up to 500 V or 690 V depending on the circuit), and up to 6 A for lower voltage ranges (24/127 V, 220/240 V, 400/440 V). For DC-13, ratings vary by voltage (e.g., 24 V up to 6 A, 48 V up to 2.8 A, down to 600 V with progressively lower current). These values enable signaling across diverse control circuits while staying within insulation and safety limits.
CAL4-11RT complies with IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10, with additional CE/UKCA conformity. This matters for regulatory compliance, safety certification, and cross-border procurement, reducing integration risk in multi-site projects and simplifying supplier qualification for industrial automation used in rail and general machinery.
The auxiliary contact block has a net width of 12 mm, net depth of 60 mm, and net height of 69.4 mm, with a product net weight of 0.04 kg. These compact dimensions support dense panel layouts and lightweight, scalable installations in both new builds and retrofits.
Use the screw terminals with ring-tongue ferrules for secure terminations, and tighten to 1.2 N·m as specified. The right- or left-side clipping allows flexible mounting on AF contactors, reducing cabling complexity. These practices minimize loose connections, improve vibration resistance, and shorten service time during maintenance or upgrades.
