Product information

Description

The Miniature Circuit Breaker CNC NV821525 3-Pole 16 Amps C Curve 6kA Breaking Capacity is a reliable three-pole electrical protection device designed for 16 Amp circuits with a C-curve trip characteristic and a 6kA breaking capacity. It provides essential overload and short-circuit protection for residential, commercial, and industrial electrical installations, ensuring safe power distribution and system stability during fault conditions.

Advantages

This miniature circuit breaker delivers reliable performance through integrated protection against both electrical overloads and short circuits. It is engineered with an anti-mistake contact terminal block to ensure secure wiring connections. The housing is manufactured from flame-retardant materials offering high temperature resistance and impact resistance for enhanced durability in demanding environments. Additionally, it features a clear contact position indication where red indicates closed and green indicates opened for quick visual status checks.

Suitable for

  • Residential electrical distribution boards
  • Commercial building wiring systems
  • Industrial control panels
  • Protection of standard inductive loads such as small motors and lighting circuits

When it may not be suitable

This circuit breaker is not designed for main incoming supply protection in large industrial facilities requiring higher breaking capacities exceeding 6kA. It is also unsuitable for direct current DC applications as it is rated specifically for alternating current systems.

Key specifications

  • Number of poles: 3
  • Rated current: 16 A
  • Trip curve class: C
  • Rated voltage: AC 400 V
  • Insulation voltage: 500 V
  • Rated frequency: 50/60 Hz
  • Rated breaking capacity: 6000 A
  • Rated impulse withstand voltage: 6000 V
  • Mechanical life: 20000 cycles
  • Electrical life: 8000 cycles
  • Protection rating: IP20
  • Terminal type: Cable or pin-type busbar up to 25mm²
  • Mounting: DIN rail EN 60715 (35mm)
  • Operating temperature range: -5°C to +40°C
  • Dimensions: 85.5 x 78.8 x 54 mm

How to use

The device is designed for standard installation on a 35mm DIN rail using the integrated fast clip device. Connections can be made from either the top or the bottom using compatible cables or pin-type busbars with a cross-sectional area of up to 25mm². Ensure that all power is disconnected before mounting or wiring the unit. Securely tighten the terminal blocks to prevent loose connections and potential overheating during operation.

What to consider before purchase

  • Verify that the 16 Amp rating matches the current requirements of your connected electrical load
  • Confirm that the 6kA breaking capacity is sufficient for the prospective fault current at the installation site
  • Check that the available space on the DIN rail accommodates the 3-pole width dimensions of 54 mm
  • Ensure the operating environment stays within the temperature range of -5°C to +40°C

Usage recommendations

Regularly inspect the device for any signs of physical damage and verify the status indicators periodically. Ensure that installation and maintenance are performed by qualified electrical personnel in accordance with local wiring regulations and standards.

Product comparison

The Miniature Circuit Breaker CNC NV821525 3-Pole 16 Amps C Curve 6kA Breaking Capacity is compared against similar three-pole and multi-pole circuit protection devices from CNC. All compared models share the same manufacturer, C-curve tripping characteristic, 6kA breaking capacity, and suitability for residential, commercial, and industrial distribution panels. The main practical differences lie in their rated current and pole count, which directly determine electrical load capacity and network configuration.

⚙️ The table below compares the rated current, pole count, breaking capacity, tripping curve, and practical application of each model.
