Why Choose the Chint NB1-63BH1P32 Miniature Circuit Breaker?

The Chint NB1-63BH1P32 is a compact and dependable miniature circuit breaker (MCB) designed to protect low voltage electrical circuits against overloads and short circuits. As part of the Chint NB1-63H series, it provides reliable circuit protection for residential, commercial and light industrial installations where a higher breaking capacity may be required.

This 1 pole B curve MCB features a 32 A rated current, making it suitable for radial circuits, commercial distribution boards, power circuits and general-purpose electrical installations. The B curve tripping characteristic provides fast protection for circuits with low inrush currents.

With a rated short-circuit breaking capacity of 10 kA and a standard 35 mm DIN rail mounting format, the NB1-63BH1P32 is easy to install within consumer units, distribution boards and electrical control panels. Its compact modular construction supports neat installation and dependable long-term performance.

Key Advantages

  • Compact 1 pole miniature circuit breaker.
  • 32 A rated current for general-purpose electrical circuits.
  • B curve trip characteristic for circuits with low inrush current.
  • 10 kA short-circuit breaking capacity.
  • Reliable overload and short-circuit protection.
  • Quick DIN rail installation in distribution boards and control panels.

Key Features

  • Chint NB1-63H series MCB.
  • 32 A rated current.
  • B curve tripping characteristic.
  • 1 pole configuration.
  • 10 kA breaking capacity.
  • 230 V AC rated voltage.
  • DIN rail mounting.

Reliable Protection for General Electrical Circuits

Miniature circuit breakers such as the Chint NB1-63BH1P32 automatically disconnect electrical circuits when overloads or short circuits occur. This helps protect cables, connected equipment and electrical installations from damage caused by excessive current.

The B curve characteristic trips between approximately 3 and 5 times the rated current, making this breaker ideal for radial circuits, socket circuits, lighting circuits and other circuits with relatively low inrush currents.

Typical Applications

  • Residential consumer units.
  • Commercial distribution boards.
  • Radial power circuits.
  • Socket outlet circuits.
  • Control and auxiliary circuits.
  • General electrical installations requiring 32 A protection.
