ABB 2CHX578744A4000 Flush Mounted Inserts - 2 NC, 10 A
Part Number: 2CHX578744A4000
Quick Summary
ABB 2CHX578744A4000 flush mounted inserts provide two NC contacts for 1-gang, 2-pole control. Engineers often struggle with wiring complexity and limited panel space when retrofitting control points. RoHS and REACH declarations, along with WEEE classification, reinforce regulatory compliance across Europe for durable, responsible production. The assembly features IP20 protection and a 10 A rating, delivering reliable performance in enclosed panels. With compact mounting and screw or claw fastening, these inserts streamline installation, reduce labor time, and improve long-term maintenance in industrial control cabinets. Design tolerances align with common panel cutouts and 2P 1-gang configurations, minimizing rework. In projects targeting high reliability, these inserts help meet uptime targets and reduce cascade failures in automation lines.

FAQs
This ABB insert supports flush-mounted installation with mounting via claw or screw, enabling a low-profile fit on 1-gang, 2-pole front panels. The combination simplifies retrofits and standardizes panel interfaces, reducing the need for custom mounting brackets and minimizing panel interference during installation.
Yes. The device uses a rocker push-switch mechanism designed in line with IEC 60947-5-1 standards and provides two Normally Closed (NC) contacts for 1-gang, 2-pole control. This configuration supports reliable interlocks and safe shutdown signaling in typical machine-control circuits.
The insert includes RoHS and REACH declarations, along with a WEEE category designation. These assurances support regulatory compliance for European manufacturing and facilitate supplier qualification in audited supply chains.
The device is rated for 250 V and 10 A, with two NC contacts and 2P configuration. Built-in depth is 12 mm, and the unit weighs 42.287 g, making it suitable for compact, space-constrained control panels without sacrificing performance.
Its compact profile, screw/claw mounting options, and robust regulatory compliance reduce installation time, minimize panel rework, and lower maintenance costs. The two NC contacts provide reliable signaling for interlocks, contributing to higher uptime and lower downstream downtime in automation lines.
