IEK KARAT BA47-29 series circuit breakers

The CHIP and DIP warehouse has a wide range of KARAT BA47-29 series circuit breakers. The range includes single-pole, two-pole, three-pole and four-pole switches.

The VA47-29 circuit breakers are designed to operate in single-phase or three-phase alternating current electrical networks with a rated voltage of up to 400V and a frequency of 50 Hz. They are used to protect distribution and group circuits with different loads: – electrical appliances, lighting – switches with characteristic B, – motors with small starting currents (compressor, fan) – switches with characteristic C, – motors with large starting currents (lifting mechanisms, pumps) – switches with characteristic D.

The BA47-29 circuit breakers are recommended for use in input and distribution devices for residential and public buildings. The switches perform the functions of automatic shutdown of the electrical installation in case of overcurrent (overload or short circuit) and operational control of sections of electrical circuits.

The main advantages of the BA47-29 series

• Two types of overload and short circuit protection.
• A complete set of additional devices with the possibility of simple self-installation:
  - KS47 status contact;
  - status contact KSV47;
  - minimum voltage release RMM47;
  - independent release PH47.
• Advanced arc extinguishing system: extended service life, increased resistance to short-circuit currents.
• The possibility of simultaneous connection by a FORK bus and a flexible conductor for distributing circuit power through the upper terminals, as well as the possibility of connection by a PIN bus.
• Wide operating temperature range from -40 to +50°C.
• New ergonomic design of the on/off handle.

Design features

• Quick mounting on a DIN rail using a double fixed position latch.
• The presence of a contact position indicator.
• The notches on the contact clamps reduce heat losses and increase the mechanical stability of the joint.
• Increased housing strength in the conductor connection area.
