ZL2-V Series
Class II secondary protection, nominal 20kA / max 40kA discharge, low residual voltage Up 1.5kV, response <=50ns, 2P/4P, 35mm rail mass deployment.

Product Overview
The Type 2 varistor surge protective device complies with Type 2 power surge protection standards. Installed between the power supply system and equipment, it suppresses induced lightning strikes and internal grid overvoltages. With high-quality varistor elements, it delivers large discharge capacity and low residual voltage output, responds rapidly, and effectively reduces the risk of equipment damage. The product supports 2P/4P wiring modes, features a built-in failure indication window, standard 35mm DIN-rail mounting, and a compact structure with a small footprint, ideal for batch deployment in distribution cabinets. Models with "S" remote signal feature built-in dry contacts that can be connected to monitoring systems to report failure status.
Core Capabilities
Type 2 lightning protection with a nominal discharge current of 20kA and maximum of 40kA. Voltage protection level as low as 1.5kV with ≤50ns response time. Multiple 2P/4P specifications compatible with various Uc voltages of 275V/385V. Models with "S" support remote signal monitoring to report failure status. Product Features
