Features and benefits:

• High breaking capacity of 25 kA at 415 V AC enables use in high fault-current environments without requiring additional current-limiting devices
• EverLink lug terminals accept wide conductor range (2.5-95 mm²) in aluminium or copper, simplifying installation and cable management
• Adjustable long-time pick-up (0.7-1 x In) allows fine-tuning of thermal protection to match actual load characteristics
• Compact 9-module DIN width with horizontal and vertical handle mounting positions provides flexible panel layout options
• One slot each for auxiliary contact (OF), alarm contact (SD), and voltage release (MN or MX) enables easy monitoring and remote tripping integration
• Halogen-free plastic parts and PVC-free construction support environmental compliance requirements

Applications:

• Main and outgoing circuit protection in industrial distribution boards and motor control centres
• Feeder protection in commercial buildings, data centres, and infrastructure switchboards
• Protection of sub-distribution panels in manufacturing facilities where high fault levels are present
• Machine builder panels requiring compact footprint with high breaking performance

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