FAQs
The CA5-40N-W is a 4P auxiliary block designed to front-mount with ABB N-series starters such as N22E, N31E, and N40E. It provides four normally open contacts to signal machine status, interlocking signals, or safety interlocks, reducing wiring complexity and enabling reliable control logic coupling with the host contactor.
Installers should ensure tight, consistent torque on each screw terminal to maintain low contact resistance. The block is rated IP20 for auxiliary terminals, so keep connectors clean and dry in standard industrial environments. Use the front-access design to simplify wiring runs and facilitate quick field amendments without panel removal.
AC-15 ratings include up to 2 A at 500–690 V, while DC-13 ratings vary by voltage from 24 V to 250 V with currents from 0.3 A to 6 A depending on voltage. These figures support signaling and switching of auxiliary circuits in typical control panel applications, aligning with IEC 60947-5-1 guidelines.
The CA5-40N-W carries CE and UKCA declarations of conformity and UL certification, alongside RoHS and REACH compliance. These certifications support regulatory acceptance across Europe, the UK, and North America, easing procurement for multinational projects and ensuring documentation aligns with vendor quality programs.
Using a four NO auxiliary block reduces wiring errors, shortens commissioning time, and simplifies future maintenance by providing a clearly labeled signaling path. With a 90-piece MOQ and compatibility with standard ABB components, projects can achieve lower total cost of ownership through faster upgrades, easier spares management, and robust control reliability.
