Schneider Electric ComPacT NSXm – 3P 63A Circuit Breaker, 25kA at 415VAC
Product Description
The Schneider Electric ComPacT NSXm (C11B3TM063L) is a compact and high-performance molded case circuit breaker (MCCB) designed for low-voltage distribution applications. With a 63A rated current and a 25kA breaking capacity at 415V AC, it provides robust and reliable protection for small to medium-sized electrical systems.
Engineered with EverLink technology, this MCCB ensures secure and long-lasting connections, reducing the risk of overheating and improving safety. It supports both DIN rail and plate mounting, making installation quick and flexible.
The thermal-magnetic (TM-D) trip unit provides dependable long-time (L) and instantaneous (I) protection, while its compact size (81mm x 137mm x 80mm) makes it one of the smallest MCCBs on the market.
Designed to meet IEC 60947-2 standards and marine specifications, the ComPacT NSXm offers durability, sustainability, and advanced features such as externally visible spring-type auxiliaries and signaling options.
