Circuit Breaker Test Equipment with 3 Test Stations And 1A–1800 A Output Current
This specialized test equipment is engineered for comprehensive time-delay tripping characteristic analysis of circuit breakers, ensuring compliance with international standards and manufacturing quality control requirements.
Product Overview
Designed and manufactured according to customer technical specifications, this equipment meets IEC 60898-1 2003 clause 9.10.1 and EN 60898-1 2003 clause 9.10.1 standards. It performs critical time-delay tripping tests by applying 1.13 and 1.45 times the rated current to verify breaker performance within specified time parameters.
Key Applications
Factory inspection and quality control for molded-case circuit breakers (MCCB)
Performance testing for air circuit breakers (ACB)
Essential electrical performance validation for circuit breaker manufacturers
Equipment Features
Rapid product loading and automated testing procedures
Automatic pass/fail judgment capabilities
High-quality aluminum alloy steel construction
Anti-static, anti-rust, and corrosion-resistant panel finishes
Integrated operation panel with power switch and multiple wire terminals
User-friendly design with reliable performance and aesthetic appeal
Working Principle
The equipment operates on a low-voltage, high-current output principle. An internal high-current isolation transformer generates the required test current. Operators set target current values via the touch screen interface, and the constant-current source automatically adjusts the transformer's primary input voltage to maintain stable current output.
The touch screen interface enables precise setting of test duration parameters and compares actual tripping times against specifications, providing automated determination of circuit breaker compliance.
