4743 >> Auxiliary contact block
Four normally open contacts in a 4P auxiliary block ensure independent signaling across four circuits, boosting reliability while simplifying panel wiring. This configuration reduces cross-talk and mis-assembly risk, delivering consistent control signals to NFZB/NFB contactor relays in manufacturing lines. Front-mounted design with screw terminals for ring tongue ferrules improves installation speed and termination security. The non-detachable conic washer enables fast, high-torque cable tightening, minimizing loose connections and post-installation faults in crowded control cabinets. Rated for auxiliary circuits up to 690 V and 50/60 Hz, with Ith of 16 A and varied Ie values across voltages, it supports common industrial control loads while preserving safety margins. The combination of 6 kV impulse withstand and UL/CSA CE certifications provides regulatory confidence and longer service life in rail, machine tool, and packaging lines. IP20 protection on auxiliary terminals guards against incidental dust ingress in indoor panels, while the specified tightening torque of 1.2 N·m ensures robust, repeatable terminations. Compatibility with NFZB22E/NFB22E, NFZB31E/NFB31E, NFZB40E/NFB40E series contactors simplifies spare parts planning and stocking for OEMs and integrators. Using the CA4..RT family block with AF09..38(Z)B relays streamlines retrofits and upgrades, supporting faster project delivery and lower total cost of ownership. Compliance and documentation—CE, UL/CSA, UR Certificates, and DoC—help meet procurement requirements and accelerate approvals.

FAQs
The 1SBN010142R1240 is a CA4 family auxiliary block designed for front-m mounting with NFZB/NFB contactors and NF(Z)B..RT relays. It uses screw terminals and is intended for front mounting on compatible AF range assemblies. Ensure ring-terminal ferrule connections are tightened to 1.2 N·m for reliable terminations in standard industrial panels.
Auxiliary circuit rated at 690 V with a frequency of 50/60 Hz. Conduction is rated for 16 A Ith, with operational currents (Ie) specified across voltages up to 690 V. It also features a 6 kV impulse withstand voltage and a conservative AC-15/DC-13 switching profile, suitable for common control and signaling tasks in industrial equipment.
The block adheres to IEC/EN 60947-5-1, UL 508, and CSA C22.2 No. 14-10. It carries CE marking and UL/CSA listing with UR and DoC documentation, and IP20 protection on auxiliary terminals, supporting global regulatory compliance and safe operation in multiple regions.
Screw terminals designed for ring tongue ferrules enable secure, corrosion-resistant terminations with straightforward tightening. The conic washer facilitates fast, reliable tightening, reducing installer time and the risk of loose connections. This translates into lower maintenance needs and fewer intermittent contact issues in dense control cabinets.
Yes. The CA4-RT family compatibility with NFZB/NFB contactors supports retrofits and upgrades, reducing stock variety and enabling faster project delivery. This makes it easier to replace aging auxiliary blocks without changing the contactor baseline, while maintaining compliance with CE/UL/CSA standards and preserving control reliability.
