• Ics equals 100% of Icn, delivering full-rated service breaking capacity without derating
• Approved for isolation duty per EN/IEC 60898-1, removing the need for a separate disconnector
• Compatible with comb busbars via double-connection lower terminals, simplifying three-phase distribution wiring
• Limitation class 3 minimises let-through energy, reducing thermal and mechanical stress on downstream equipment
• Wide operating range from -25 to 70°C suits both indoor distribution boards and more demanding industrial enclosures

Applications:

• Final distribution boards in commercial and industrial buildings
• Three-phase branch circuit protection in residential and tertiary electrical installations
• Industrial control panels and machine switchboards requiring thermomagnetic MCB protection
• Sub-distribution switchboards where isolation capability is required at the breaker

Compliant with EN/IEC 60898-1. Part of the Schneider Electric Acti 9 range.
