The NHP MOD6+ MD6M263 is a C Curve Miniature Circuit Breaker (MCB) designed for reliable overcurrent protection in residential, commercial, and light industrial applications. With a 6kA short-circuit rating and compliance with AS/NZS 60898, this breaker provides robust and efficient circuit protection for two-phase or single-phase with neutral systems.

Key Features:

  • 2 Pole Protection: Simultaneously disconnects both active conductors or active and neutral, enhancing safety and compliance.
  • C Curve Tripping Characteristics: Trips at 5 to 10 times the rated current, suitable for general-purpose applications such as lighting, appliances, and socket outlets.
  • 6kA Short Circuit Rating: Tested to AS/NZS 60898 standards, providing protection against short-circuit currents at 230V and 400V AC.
  • High Insulation & Impulse Withstand: Rated insulation voltage of 440V and impulse withstand of 4kV, ensuring safety under fault conditions.
  • IP40 Protection: Ideal for installation within enclosures, offering resistance to dust and ingress.
  • Dual Wiring Capability: Accepts both solid-core (0.75–25 mm²) and multi-stranded (0.75–16 mm²) conductors.

The NHP MOD6+ MD6M2 2 Pole MCB is a compact, high-performance circuit breaker designed for safe, effective overcurrent protection. Its C curve response, durable design, and wide operating temperature range make it a trusted choice for modern electrical installations requiring two-pole disconnection.

Q: What does a 2-pole MCB protect?
A: A 2-pole MCB protects both conductors (e.g., active and neutral or two actives), ensuring a complete disconnection of the circuit.

Q: Can this MCB be used in a 3-phase system?
A: It can be used in two-phase parts of a 3-phase system or for single-phase applications requiring disconnection of both conductors.

Q: Is it compatible with all switchboards?
A: Yes, it is DIN rail mountable and fits standard 2-module DIN enclosures and larger.

Q: What is the benefit of the C curve?
A: The C curve allows for protection of circuits with moderate inrush currents, such as small motors or fluorescent lighting.
