Features and benefits:

• Micrologic 2.3 electronic trip unit with adjustable Ir and Isd settings enables precise selective coordination with upstream and downstream protective devices
• Breaking capacity up to 100 kA at 220/240 V AC ensures reliable fault protection in high-demand distribution networks
• Thermal memory (20 minutes) reduces nuisance re-tripping by retaining thermal state before and after a tripping event
• Local LED signalling indicates device ready (green flashing), overload at 90% Ir (orange), and overload at 105% Ir (red)
• Six auxiliary slots allow flexible addition of signalling, monitoring, and control accessories

Applications:

• Main and sub-main circuit protection in industrial power distribution boards
• Protection of large electrical loads in commercial and industrial installations
• Switchgear and controlgear assemblies requiring high short-circuit breaking capacity
• Distribution systems where selective coordination between protective devices is required

Compliant with EN/IEC 60947-2 and UL 60947-4-1. Part of the Schneider Electric ComPacT NSX new generation range.
