Product information

Description

The CNC NV821518 2-Pole 25A Miniature Circuit Breaker Class C 6kA is a dependable electrical protection device designed to safeguard residential and commercial electrical distribution systems against overloads and short circuits. Featuring a robust 2-pole configuration and a rated current of 25A, this miniature circuit breaker ensures continuous safety and reliable performance in standard wiring installations. Built with high-quality flame-retardant materials, it offers excellent temperature and impact resistance, while the clear contact position indicator displays red for closed and green for opened states.

Advantages

This miniature circuit breaker delivers reliable performance through integrated overload and short-circuit protection mechanisms. The anti-mistake contact terminal block ensures secure and correct wiring during installation. Constructed from flame-retardant materials, the device withstands high temperatures and physical impacts effectively. Users can easily monitor the operational status via the mechanical contact position indication. With a mechanical life of up to 20,000 cycles and an electrical life of 8,000 cycles, it provides long-lasting durability for various electrical distribution networks.

Suitable for

  • Residential electrical distribution boards and consumer units
  • Commercial building wiring and sub-distribution panels
  • Protection of standard household and office appliances
  • Standard 35mm DIN rail installations in electrical enclosures

When it may not be suitable

This miniature circuit breaker is not designed for direct current applications, as it is rated for AC circuits. It may also be unsuitable for industrial environments requiring breaking capacities higher than 6kA or operating outside the specified temperature range of -5°C to +40°C.

Key specifications

  • Number of poles: 2
  • Rated current: 25 A
  • Trip characteristic class: C
  • Rated voltage: AC 400 V
  • Rated breaking capacity: 6000 A
  • Mechanical life: 20000 cycles
  • Electrical life: 8000 cycles
  • Terminal connection type: cable or pin-type busbar up to 25mm²
  • Mounting: 35mm DIN rail EN 60715

How to use

The device is designed for professional installation on a standard 35mm DIN rail using the fast clip mounting mechanism. 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 the electrical supply is completely disconnected before mounting, wiring, or performing maintenance on the circuit breaker.

What to consider before purchase

  • Verify that the 25A rated current matches the electrical load requirements of your circuit
  • Ensure the 6kA breaking capacity is sufficient for the prospective fault current at the installation site
  • Check that the available space on the 35mm DIN rail accommodates the physical dimensions of the device
  • Confirm that operating temperatures at the installation location remain within the specified limits
Usage recommendations: Installation should be performed strictly by a qualified electrician in compliance with local electrical codes and standards. Regularly inspect the device for physical damage and verify the integrity of terminal connections during routine electrical maintenance.
