SBLL-3P20A Self-Ballasted Lamp Switch Load Breaking Capacity Tester

The SBLL-3P20A Self-Ballasted Lamp Switch Load Breaking Capacity Tester evaluates the load interruption capability of switches designed for self-ballasted lamp circuits. This equipment determines whether switches exhibit operational anomalies—including sustained arcing, contact welding, or delayed opening/closing—when controlling LED loads, while verifying their capacity to withstand electrical and thermal stresses without excessive degradation or hazardous effects.

The instrument incorporates an integrated voltage regulation system, eliminating the requirement for external voltage stabilization to achieve the specified test voltage. It features a digital display for real-time monitoring of input voltage and output power parameters, complemented by an analog ammeter for precise observation of current surge characteristics.

Key technical capabilities include multi-station synchronous testing functionality, an integrated contact control mechanism, and dedicated calibration modes with specialized ports for equipment verification and parameter adjustment. The system implements configurable long-duration interruption/continuity protection with adjustable timing parameters; protection activation triggers automatic shutdown with audible/visual alarms.

When integrated with compatible plug, socket, and switch endurance testing apparatus, this system provides comprehensive compliance verification for standard switch load testing protocols.
