Product Description
Mersen STPT23 Surge Protector is a combined Type 2+3/Class II+III device engineered for industrial and commercial surge protection applications. Featuring a maximum voltage rating of 440V and maximum surge current capacity of 20 kA, it provides a very fine voltage protection level suitable for sensitive electrical and electronic equipment.
This unit is designed specifically as the last line of defense in electrical protection panels with upstream Type 2 devices, such as the STP T2 40 series, installed. The device should be mounted on a DIN rail and placed as close as possible to the equipment requiring protection to maximize the discharge efficiency and reduce residual voltage.
With compact dimensions of 90 mm height, 18 mm length, and 70 mm depth, it offers space-saving installation without sacrificing performance. Manufactured to comply with IEC 61643-11 and EN 61643-11 standards, the device assures conformity to international surge protection requirements.
The common mode N-PE (N) configuration allows optimal discharge path for voltage surges, preventing equipment damage caused by transient overvoltages. This surge protector is ideal for use in industrial automation, manufacturing, electrical distribution systems, HVAC controls, and laboratory instrumentation where reliable surge suppression is critical.
Provides Type 2+3/Class II+III combined surge protection for enhanced equipment safety. 440V maximum continuous operating voltage suitable for most industrial power systems. 20 kA maximum surge current protects against high transient surge events.
Compliant with IEC 61643-11 and EN 61643-11 standards assuring international quality and safety. Compact DIN rail mount design for ease of installation in control panels. Configuration N-PE (N) ensures effective surge current discharge path.
The Mersen STPT23 series surge protector supports critical infrastructures and industrial environments requiring stringent surge protection that complies with international standards. Protect your critical systems with this reliable, compact, and high-capacity surge protection device from Mersen.
