Features and benefits:

• EverLink connection lugs accept flexible and solid copper conductors from 2.5 to 95 mm², simplifying field wiring
• Thermo-magnetic TMD protective unit provides both thermal (overload) and instantaneous (short-circuit) protection in a single device
• High breaking capacity of 25 kA at 415 V AC covers most industrial distribution requirements
• Compact 9-module DIN width fits space-constrained distribution boards
• One auxiliary slot each for OF (auxiliary switch), SD (alarm switch), and MN/MX (voltage release), enabling flexible signalling and remote tripping
• Suitable for isolation per IEC 60947-2, eliminating the need for a separate isolator in many installations

Applications:

• Main incoming protection in industrial and commercial power distribution boards
• Sub-distribution panels requiring high short-circuit breaking capacity
• Protection of outgoing feeders in low-voltage switchgear assemblies
• Machine and equipment supply circuits in factory environments

Compliant with EN/IEC 60947-2. Part of the Schneider Electric ComPacT NSXm new generation range.
