Product Overview

This product is a Type 2 power surge protective device installed between the distribution system and equipment to discharge induced lightning strikes and internal overvoltages. It uses varistor elements for fast response and low residual voltage. It features local failure indication, optional remote signaling, and standard DIN-rail mounting, making it suitable for low-voltage distribution scenarios such as communications and industrial applications. It complies with Type 2 power surge protection standards, discharging induced lightning strikes and internal grid overvoltages to effectively reduce the risk of equipment damage. Models with "S" remote signaling include a built-in dry contact that can be connected to a monitoring system to report failure status, enabling remote O&M together with a centralized management platform.

Core capabilities

Type 2 surge protection: complies with Type 2 power surge protection standards, discharging induced lightning strikes and internal grid overvoltages. High discharge capacity: nominal discharge current up to 20kA (max 40kA), capable of withstanding high-energy surges. Low residual voltage output: voltage protection level as low as 1.5kV, response time ≤50ns, quickly clamping overvoltages. Remote signaling monitoring: models with "S" remote signaling include a built-in dry contact that can be connected to a monitoring system to report failure status. Product Features
