TZG40C Surge Protector Overview The TZG40C is a threephase surge protector designed for installation in electrical distribution systems. It mitigates transient overvoltages to help maintain reliable operation of connected equipment. Key benefits Reduces the risk of equipment interruptions caused by voltage surges by diverting transient current away from sensitive devices. discharge capacity handles large surge events while maintaining stable operation under normal conditions. to match specific installation requirements, allowing integration into a variety of electrical systems. Contains no concern chemicals according to the provided specification. Technical highlights Model: TZG40C Type: Surge protector Rated size: 275V Input voltage: approximately 385 VAC Poles: 3P plus NPE Nominal discharge current: 20 kA Maximum discharge current: 40 kA : available concern chemicals: none Compatibility and performance Intended for threephase electrical networks where a 3P plus neutral protective arrangement is required. Rated and tested to handle both routine and energy transient events within the specified discharge current range. Input voltage of approximately 385 VAC makes it suitable for common industrial and commercial threephase systems. Typical applications Electrical distribution panels in commercial buildings to protect lighting, control, and power circuits. Industrial machinery and motor control centers where transient suppression reduces downtime and maintenance needs. Renewable energy installations and inverter stations to protect power electronics from grid transients. Secondary protection for UPS systems, switchgear, and telecommunications equipment. Installation and Designed for panel or enclosure mounting in the power distribution section. Custom options available to adapt terminal configuration, mounting style, or integration with existing protection schemes. Specify model TZG40C and required parameters when requesting . What to consider when selecting Verify system nominal voltage and confirm compatibility with the listed rated size of 275V and input voltage of approximately 385 VAC. Confirm required discharge capacity based on expected installation exposure and system coordination requirements using the nominal 20 kA and maximum 40 kA ratings. Ensure the 3P plus NPE pole arrangement matches the system grounding and neutral configuration. This description reflects the TZG40C model and its specified functions and ratings for straightforward selection and integration into threephase electrical protection systems.
