Product Description

Product Introduction

Miniature circuit breaker is mainly used for protection against overload and short circuit under the AC 50Hz/60Hz, reted voltage 230V/400V and rated current from 1A to 63A/125A. It also can be used for non-frequent on-and-off switch operation under normal circumstance.

Product Features

  1. In complicance with IEC/EN62898-1. 2. With indicator function in the contact position., 3. Maximum connecting ability of 25mm² 4. Overload and short circuit protection.
  2. . High Reliability: Engineered to provide consistent performance and long service life, ensuring reliable protection for electrical circuits.
  3. Easy Integration: Compatible with a wide range of electrical systems and easily integrates with existing infrastructure.
  4. Multiple Pole Options: Available in single-pole, double-pole, and multi-pole configurations to meet various circuit requirements.

Installation Methods

  • Surface Mount: Designed for easy surface mounting on electrical panels or distribution boards.
  • Rack Mount: Suitable for installation on standard racks, allowing for a neat and organized layout.
  • Recessed Mount: Can be installed in a recessed manner for applications requiring a flush finish.

Applicable Environmental Conditions

  1. Temperature Range: Operates effectively within a wide temperature range, typically from -30°C to +70°C.
  2. Humidity: Suitable for use in environments with varying humidity levels, provided that the conditions do not promote condensation or corrosion.
  3. Altitude: Can be used at altitudes up to 2000 meters without performance degradation.
  4. Vibration and Shock: Designed to withstand typical levels of vibration and shock encountered in most industrial and commercial settings.

Product Advantages

  • 1) The combination of circuit breaker and circuit breaker should consider the instantaneous trip value of the upper circuit breaker, which should be greater than the maximum expected short circuit current at the lower circuit breaker outlet. If the impedance value of the circuit element is small when the circuit breaker is short circuited at the two stage circuit breaker, the short circuit current value is not much different, then the upper circuit breaker can choose the trip device with short delay.
  • 2) When the short-circuit circuit breaker is greater than or equal to the setting value of its instantaneous trip device, it will trip within a few milliseconds, so the lower protection electrical appliances should not use the circuit breaker to achieve selective protection requirements.
  • 3) With a short delay circuit breaker, when its time limit is set at the maximum delay, its on-off capacity decreases, therefore, in the selective protection circuit, consider the selection of the circuit breaker short delay on-off capacity should meet the requirements.
  • 4) It should also be considered that the short-circuit delay returnable characteristic of the upper circuit breaker and the action characteristic time curve of the lower circuit breaker should not intersect, and the short delay characteristic curve and the instantaneous characteristic curve should not intersect.
  • 5) When the circuit breaker is used with the fuse, the coordination of the upper and lower levels should be considered, and the ampere-second characteristic curve of the circuit breaker should be compared with the ampere-second characteristic curve of the fuse, so that it has protection selectivity in the case of short circuit current.
  • 6) When the circuit breaker is used as the protection of the distribution line, it is appropriate to choose the circuit breaker with a long delay action over current trip. When the single-phase grounding short circuit occurs at the end of the line, the short circuit current is not less than 1.5 times the setting current of the circuit breaker instantaneous or short delay over current trip.

Application Places

The circuit breaker is a commonly used electrical component ‌ its main purpose is to provide overload and short circuit protection of the circuit. ‌ When the circuit is abnormal, such as ‌ overload or short circuit, ‌ circuit breaker can automatically cut off the power supply, ‌ to prevent the occurrence of fire or electric shock and other dangerous situations. ‌ This kind of device is widely used in home, ‌ office, ‌ factory and other civil places, ‌ is an important part of low-voltage power distribution system. ‌
