High-Current ACB Universal Circuit Breaker Test Bench - China Suppliers & Factory for IEC 60947-2 Compliance
Equipment Overview
The ACB Universal Circuit Breaker High-Current Comprehensive Performance Test Bench is a professional testing system used to evaluate the overall performance characteristics of Air Circuit Breakers (ACB) under high-current operating conditions.
ACBs are critical components in low-voltage power distribution systems, requiring accurate verification of current-carrying capability, protection functions, and operational reliability.
ACBs are critical components in low-voltage power distribution systems, requiring accurate verification of current-carrying capability, protection functions, and operational reliability.
This test bench integrates high-current generation, intelligent control, and precise measurement systems, enabling comprehensive testing of long-time delay, short-time delay, instantaneous, and ground fault protection characteristics.
It also supports temperature rise, contact resistance, withstand voltage, and operational performance testing, ensuring full compliance with IEC 60947-2 standards.
Designed for heavy-duty industrial applications, the system provides stable output, high accuracy, and repeatable results, making it suitable for manufacturing plants, testing laboratories, and type-test centers.
System Configuration
The test bench typically consists of the following systems:
- Control SystemEquipped with an advanced control system and intuitive operation panel, allowing flexible setting of fault modes, test current, and delay time parameters.
- Power Supply SystemProvides stable and adjustable voltage and current output to meet the testing requirements of different types and ratings of circuit breakers.
- Fault Simulation SystemSimulates various fault conditions, including overload, short circuit, and grounding, with precise control of fault current and delay time.
- Data Recording SystemAutomatically records key parameters such as operating time, fault current, and delay cut-off time, generating clear and traceable test data for analysis and evaluation.
- Safety Protection SystemIntegrated with multiple safety protections, including overload, over-temperature, and short-circuit protection, ensuring safe operation during testing.
