Schneider C11E44V050L | Circuit breaker ComPacT NSXm E (16kA at 415VAC), 4 Poles 4d, 50A rating Micrologic 4.1 trip unit, connectors

Schneider C11E44V050L Description:

ComPacT NSXm100E is a complete 4P fixed circuit breaker designed to optimize space and breaking capacity.

The breaking capacity (Icu) is 16kA rms at 415VAC 50/60Hz. The operational voltage is 440VAC 50/60Hz.

It introduces new features like Everlink connectors technology.

It offers built-in DIN rail & plate mounting capability and spring type auxiliaries externally visible.

This 4 poles Earth Leakage Circuit Breaker (ELCB) is one of the smallest on the market.

The dimensions are 108mm (W) x 144mm (H) x 80mm (D). It ensures compliance with international standards (IEC 60947/CCC/EAC) and marine specifications.

Product Overview: The Schneider C11E44V050L surge protector is designed to protect electrical systems and equipment from transient overvoltages caused by lightning strikes, electrical switching, and other voltage spikes. It provides reliable protection to ensure the safety and longevity of connected devices.

Key Features (Typical for Schneider Surge Protectors):

  1. Type 2 Surge Protection: Typically installed at distribution boards to protect against indirect lightning strikes and switching surges.
  2. High Surge Current Capacity: Offers a robust discharge capacity to divert excess voltage away from sensitive equipment, preventing damage.
  3. Visual Indication: Equipped with status LEDs for clear indication of operational status and potential fault conditions.
  4. Modular and Compact Design: Designed for easy installation in various electrical panels and enclosures, providing flexibility in deployment and maintenance.
  5. Compliance: Meets international standards and certifications for surge protection devices, ensuring reliability and safety in operation.


  • Industrial: Protects machinery, control systems, and other critical equipment in industrial environments where voltage surges can disrupt operations.
  • Commercial: Safeguards sensitive electronic devices in offices, retail spaces, and other commercial buildings.
  • Residential: Ensures household appliances and electronics are shielded from electrical surges.

Installation: Typically installed at main distribution boards or sub-distribution boards to protect downstream equipment from transient overvoltages.

Technical Specifications (Typical):

  • Nominal Voltage: 230V AC
  • Maximum Continuous Operating Voltage: 275V AC
  • Nominal Discharge Current (In): Typically around 40 kA
  • Total Nominal Discharge Current (It): 50 kA
  • Protection Modes: L-N, L-PE, N-PE

Manufacturer: Schneider Electric, a leading global provider of energy management and automation solutions.
