Description

The Hager NCN332A is a high-performance 32A 3-pole MCB (Miniature Circuit Breaker) designed for demanding commercial and industrial applications. It offers reliable protection for three-phase circuits against both overload and short-circuit faults.

Rated at 32 amps, this MCB features a C curve tripping characteristic, making it ideal for circuits with moderate inrush currents—such as motors, fluorescent lighting, air conditioning systems, and small machinery. The C curve allows the breaker to trip at 5 to 10 times its rated current, preventing nuisance tripping while still ensuring effective fault protection.

This device offers dual breaking capacities:

  • 10kA for IEC/EN 60898 applications

  • 15kA for IEC/EN 60947-2 applications
    This makes the NCN332A suitable for a wide range of installations with higher prospective fault currents.

The 3-module width and DIN rail mounting make installation easy in standard distribution boards and panel enclosures. The terminals are designed for secure and straightforward cable connection, saving time during setup and maintenance.

Key features:

  • 32A current rating

  • 3-pole (3P) configuration for three-phase systems

  • C curve – ideal for moderate inrush loads

  • 10kA/15kA breaking capacity (dual standard rated)

  • 3-module width

  • Fully compliant with IEC/EN 60898 and 60947-2

  • Secure terminal connections

  • Quick and easy DIN rail installation

  • Trusted Hager quality and reliability

The Hager NCN332A 32A 3-pole MCB provides enhanced protection for installations where inrush currents are present and system integrity is critical. It is the ideal solution for protecting distribution circuits in factories, workshops, warehouses, and larger commercial buildings.

Choose the 32A 3-pole MCB from Hager for robust, standards-compliant performance in every phase of your electrical installation.

Frequently asked questions

MCBs are used in the consumer unit (distribution board) of three-phase installations to protect individual circuits. They are typically installed to protect circuits supplying sockets, lighting, appliances, and other electrical loads.

In three-phase electrical systems, MCBs provide essential protection against overcurrents that could damage wiring, equipment, and appliances. They help ensure electrical safety and prevent fire hazards caused by excessive current flow.

Yes, MCBs are generally required in three-phase installations to comply with electrical regulations (e.g., BS 7671). They are a fundamental part of circuit protection, ensuring that circuits are automatically disconnected in case of overcurrents.

MCBs for three-phase systems come in various ratings to match the current requirements of different circuits. They may also vary in characteristics such as breaking capacity (the maximum fault current they can safely interrupt) and tripping curves (to accommodate different types of loads).

When selecting an MCB for a three-phase system, consider:

  • Current Rating: Ensure the MCB’s current rating matches or slightly exceeds the maximum current expected in the circuit it protects.
  • Breaking Capacity: Choose an MCB with an adequate breaking capacity to safely interrupt the maximum fault current that could occur in the circuit.
  • Tripping Curve: Select the tripping curve (e.g., B, C, or D) based on the type of load and expected inrush currents to avoid nuisance tripping.
