Blue Jay DZ47 Miniature Circuit Breaker

The Blue Jay DZ47 Miniature Circuit Breaker is part of an AC MCB circuit breaker series. It is primarily employed in lighting distribution systems and motor distribution systems to safeguard against both overload and short-circuit situations.

Its construction features highly fire-resistant and shockproof plastics. The DZ47 Miniature Circuit Breaker finds its primary application in single-pole 230V or two, three, and four-pole 400V circuits operating at AC 50/60Hz.

Features of Blue Jay DZ47 Miniature Circuit Breaker

  • Effective Air Circulation: When two poles are positioned adjacent to each other, they create channels that form a tunnel, facilitating efficient air circulation around each individual pole.
  • DIN Rail Mounting: Designed for easy mounting and demounting within a distribution board (DB) using DIN rails.
  • Dual Connect Terminal: The incoming side features dual connect terminals, accommodating two types of busbars – Fork Type and Pin Type.
  • Cable Compatibility: The terminals are suitable for cables with a cross-sectional area of up to 25 mm^2, making them suitable for both copper and aluminum cables.
  • Safety Positions: It has an “OFF” position for personal safety during maintenance and an “ON” position for critical load operation.
  • Trip-Free Mechanism: The MCB is equipped with a trip-free mechanism, ensuring that it trips even if forcibly held in the “ON” position.
  • Energy Efficiency: It minimizes watt loss, resulting in low energy consumption and greater energy efficiency.
