FAQs
Yes. The CA4-01K-T is designed as a 1-pole front-mounted auxiliary contact block compatible with ABB AF09 through AF96 contactors and NF contactor relays. It features a 10 mm width and Push-In Spring terminals for quick, secure wiring, enabling straightforward retrofits and uniform control logic across multiple ABB families.
The block offers an auxiliary circuit voltage of up to 690 V with a rated frequency of 50/60 Hz. It provides a conventional free-air thermal current of 16 A (Θ = 40 °C) and supports AC-15 and DC-13 operational currents across a range of voltages, plus a 6 kV impulse withstand and 140 A short-time current for 0.1 s. These specs support reliable control circuit operation in typical industrial panels.
Push-In Spring terminals enable tool-free wire insertion, reducing commissioning time and wiring errors. They accept flexible and solid conductors within specified cross-sections, support rapid field connections, and promote consistent termination quality across installations. This makes on-site assembly faster and maintenance less prone to loosening or miswiring issues.
The CA4-01K-T adheres to IEC/EN 60947-5-1, UL 60947-5-1, and CSA C22.2 standards, with RoHS and WEEE compliance. These approvals reduce regulatory risk in global deployments, ensure safety and interoperability with other ABB devices, and support traceability for audits and certifications in diverse markets.
Using the CA4-01K-T standardizes auxiliary contacts across ABB AF-series panels, enabling bulk procurement and consistent wiring practices. It reduces installation time with Push-In Spring terminals, improves reliability in control circuits, and lowers maintenance overhead through compliant, globally recognized specifications.
