ABB 1SBN010040R1204 Auxiliary Contact Block - 4-Pole N

Feature: The 4-pole, front-mounted design with screw terminals provides a compact interface that fits alongside ABB contactors in tight control panels. It reduces wiring reach and simplifies panel routing for faster assembly. The screw-terminals deliver robust, vibration‑resistant connections that maintain signal integrity in demanding industrial environments. Business Impact: By matching terminal arrangements to 4‑pole N-series relays, the block minimizes mis-wiring and speeds up replacement during maintenance. This consistency also supports shorter training cycles for technicians and reduces spare-part variety across projects. In practice, it translates to lower downtime and more predictable maintenance windows. Application: The CA5-04N variant offers 0 normally open and 4 normally closed instantaneous contacts, aligning with common control schemes for interlocks and safety circuits in machine automation. The 4‑pole configuration enables status feedback for multiple lines without adding separate devices. Its terminal assortment is designed to mirror the marking of 4-pole N-series relays, simplifying documentation and wiring diagrams. Installation: Front-mounting simplifies mounting on standard contactors and reduces installation time in legacy panels. The screw terminals accept common conductor sizes, supporting a wide range of wire gauges and enabling secure field connections. The block is designed to integrate with ABB protection and circuit-control ecosystems, ensuring compatibility with existing relays, wiring harnesses, and mounting hardware. Inventory and planning: The product is listed with a 25‑day lead time in typical sourcing scenarios, helping procurement teams schedule stocking and avoid stockouts. It is available in multiple supplier configurations to support regional deployment, with stock that enables From stock if available and predictable delivery timelines. This improves project scheduling and maintenance planning for industrial facilities. Industry relevance and business outcomes: As a standard accessory in electrical protection and circuit control, this block enables reliable control logic, safer interlocks, and traceable wiring documentation. In high-volume manufacturing, its consistent form factor reduces engineering overhead and accelerates time-to-value for new line installations. Overall, it contributes to improved uptime, safer operations, and lower total cost of ownership.
