Description

50A Three Phase RCBO – Three Module – 3P+N Pole B Curve 10kA Type A 30mA

Live Electrical RTN350B-030N

This RCBO is specifically designed for Live Electrical Three Phase Distribution Boards, offering advanced protection and reliability. Combining the functions of an RCD (Residual Current Device) and an MCB (Miniature Circuit Breaker), it safeguards against overloads, short circuits, and earth leakage faults. Its Type A functionality ensures detection of both AC (Alternating Current) and pulsating DC (Direct Current) residual currents, making it ideal for modern electrical systems with sensitive equipment.

Key Features of Three Phase RCBO 50A B Curve

  • Rated current: 50A for precise and safe load handling.
  • Fault current: 10kA, ensuring robust protection against high fault conditions.
  • RCD trip rating: 30mA to safeguard against harmful leakage currents.
  • Curve B: Provides fast disconnection, suitable for residential and light commercial applications.
  • Type A: Detects both AC and pulsating DC residual currents for enhanced safety.

Applications

  • Designed specifically for Live Electrical Three Phase Distribution Boards.
  • Perfect for industrial and commercial environments with modern electrical loads.
  • Ideal for systems with sensitive equipment prone to pulsating DC leakage currents.

Specifications

  • Rated Current: 50A
  • Fault Current: 10kA
  • RCD Trip Rating: 30mA
  • Curve Type: B
  • RCD Type: A (AC and pulsating DC detection)
  • Compliance: BS EN 61009

Why Choose This Product?

This RCBO combines the advanced protection of an RCD with the precise overload and short-circuit protection of an MCB. The Type A RCD capability ensures safety in installations with mixed loads, including those generating pulsating DC currents, such as LED lighting, EV chargers, and other electronics. Designed for seamless integration into Live Electrical Three Phase Distribution Boards, it is a trusted choice for modern systems.
