Legrand MCB Circuit Breaker 40A Triple Pole 10kA

Description

Legrand MCB Circuit Breaker 40A Triple Pole 10kA – Robust Three-Phase Protection for High-Demand Electrical Installations

The Legrand MCB Circuit Breaker 40A Triple Pole 10kA is a top-tier miniature circuit breaker engineered to provide comprehensive protection for three-phase power systems. Built by Legrand, a global leader in electrical safety and infrastructure solutions, this MCB offers unmatched reliability, high breaking capacity, and consistent performance in both commercial and industrial applications.

Designed to handle 40 Amperes of current and equipped with a 10kA short-circuit breaking capacity, this triple pole breaker is ideal for safeguarding industrial machinery, commercial HVAC systems, large motor loads, and three-phase equipment. Its triple pole configuration ensures that all three phases (L1, L2, L3) are disconnected simultaneously during a fault, minimizing equipment damage, reducing safety risks, and preserving system balance.

Key Features:

• Triple Pole (TP) Configuration
  Provides protection for all three phases simultaneously, ensuring complete disconnection during a fault. Ideal for balanced three-phase loads and essential for industrial or commercial systems using three-phase power.

• Rated Current: 40 Amperes
  Designed to support circuits with medium to heavy electrical loads, such as industrial motors, compressors, large pumps, production equipment, and distribution panels.

• High Short-Circuit Breaking Capacity: 10kA (10,000 Amps)
  With the ability to safely interrupt high fault currents, this breaker offers robust protection in demanding environments, maintaining operational safety and system reliability.

• Thermal-Magnetic Tripping Mechanism

  • Thermal Protection: Automatically trips in case of prolonged overcurrent, protecting against overheating and cable damage.

  • Magnetic Protection: Instant trip feature reacts immediately to short-circuit conditions, preventing equipment burnouts and reducing fire risk.

• Premium Flame-Retardant Construction
  Encased in durable, high-grade thermoplastic, the MCB is resistant to heat, fire, and impact, making it ideal for use in tough commercial or industrial settings.

• DIN Rail Mounting System
  Allows for quick, secure, and standardized installation in any DIN rail-equipped distribution board or enclosure, suitable for both new installations and upgrades.

• Compliance with International Standards
  Built to meet IEC 60898 and other global electrical safety norms, ensuring certified protection and long-term durability.

Applications:

• Three-phase industrial machinery and equipment

• HVAC systems, chillers, and refrigeration units

• Elevators, escalators, and automated building systems

• Commercial buildings and office complexes

• Workshops, factories, and warehouses

• Agricultural processing equipment

• Main and sub-distribution panels in industrial facilities
