Schneider Electric C11B3MA080BZ ComPacT NSX100m Motor Protection Circuit Breaker – 80 A, 3P3D, 25 kA @ 400 V AC, MA Magnetic Trip Unit

製品説明

The Schneider Electric C11B3MA080BZ is a 3-pole molded case circuit breaker from the ComPacT NSX100m range, specifically configured for motor protection with an MA magnetic-only trip unit. Rated 80 A at 65 °C, it delivers an ultimate breaking capacity (Icu) of 25 kA at 380–415 V AC and 50 kA at 220–240 V AC, with service breaking capacity (Ics) equal to 100% of Icu. The MA trip unit provides adjustable magnetic short-circuit protection from 6 to 14 × In, making it suitable for direct-on-line motor starters where separate overload protection is provided by a contactor-mounted thermal relay. The breaker features busbar connectors for main circuit termination, a fixed manual handle, and DIN rail or base plate mounting. It is rated for operation up to 690 V AC and is certified to IEC 60947-2 and IEC 60947-4-1, with CCC approval.

標準機能

• 80 A Motor Protection Rating: Rated current of 80 A at 65 °C, optimized for motor feeder protection in industrial control panels.
• MA Magnetic-Only Trip Unit: Provides short-circuit protection only, with an adjustable magnetic trip range of 6–14 × In, allowing separate thermal overload protection to be handled by a contactor-mounted relay.
• 25 kA Breaking Capacity (B Class): Delivers 25 kA Icu at 380–415 V AC, 50 kA at 220–240 V AC, and 20 kA at 440 V AC, with Ics equal to 100% of Icu.
• 3P3D Configuration: Three poles, three protected, with a 27 mm pole pitch (35 mm with extenders) for phase isolation.
• Busbar Connectors: Main circuit termination via busbar connectors, supporting 70–120 mm² stranded cable or 50–95 mm² flexible cable with ferrules via EverLink.
• 柔軟な取り付け: Supports DIN rail clip-on mounting or screw fixing on a base plate, with a fixed manual direct handle as standard.
• Motor Protection Application: Designed specifically for motor protection, with electrical life of 10,000 operations at 440 V In and 20,000 operations at 440 V In/2.
