FAQs
The CA3-01 is a front-mounted auxiliary contact block designed to fit AS/L-09 to NS contactors. It uses screw terminals for secure connections and aligns with ABB mounting interfaces on AS09, AS12, AS16, ASL09, ASL12, ASL16, VAS09, VAS12, VAS16, VASL09, VASL12, VASL16, NS, and NSL families. When mounting, align with the contactor, tighten terminals to the recommended torque, and verify that the NC contact is clearly indicating the circuit status.
CA3-01 provides a 1 NC contact with 690 V insulation for auxiliary and main circuits and operates at 50/60 Hz. It has Ith rated at 10 A, and the rated operational currents include AC-15 and DC-13 values dependent on voltage. It supports short-time withstand currents up to 140 A for 0.1 s and 100 A for 1 s, suitable for typical industrial control panels.
Yes. The CA3-01/CA3 series carries CE, UKCA, UL, CCC, CQC, GOST, and RoHS/REACH declarations. It is designed to meet global compliance requirements for motor control and protection equipment, enabling smoother procurement across regions. Additional declarations include DoC and conformity statements for CCC and UKCA where applicable, ensuring wide market compatibility.
The CA3-01 measures 44.2 mm in width, 33.5 mm in height, and 9.5 mm in depth, with a weight of 0.011 kg. It uses screw terminals for both auxiliary and control circuits, and is IP20 protected. These dimensions and terminals support easy integration into compact control cabinets and straightforward field wiring.
By adding a 1NC auxiliary contact, the CA3-01 improves fault diagnosis and status indication without complex wiring, reducing commissioning time and wiring errors. Its compatibility with AS/NS contactors streamlines retrofits and upgrades, while global certifications simplify cross-border procurement and ensure regulatory compliance across plant locations.
