1TVS151800S3419 ABB EPX-SURGE-T123 Type 1, 2 and 3 Surge Protection Kit

Why Choose the ABB EPX-SURGE-T123 Type 1, 2 and 3 Surge Protection Kit?

The ABB EPX-SURGE-T123 is a dedicated combined Type 1, Type 2 and Type 3 surge protection kit designed for integration into compatible ABB Protecta Power low-voltage electrical distribution assemblies. As part of the ABB Protecta Power enclosure and distribution accessory range, this kit supports protection against transient overvoltages associated with lightning activity, electrical switching operations and other disturbances within electrical power systems.

Featuring a Type 1+2+3 surge protection classification, the EPX-SURGE-T123 provides a coordinated approach to surge protection at the distribution board level. The combination of three surge protection classifications helps manage high-energy lightning-related impulses, switching surges and residual transient overvoltages that could otherwise affect connected electrical and electronic equipment.

Identified by ABB order code 1TVS151800S3419, the EPX-SURGE-T123 is intended for ABB Protecta Power electrical distribution installations. Its dedicated kit format supports the integration of surge protection into compatible panelboard configurations, making it suitable for commercial buildings, industrial facilities and electrical infrastructure where effective transient overvoltage protection is required.

Comprehensive Surge Protection for Electrical Distribution Systems

Transient overvoltages can arise from lightning activity, switching operations and disturbances within electrical supply networks. The ABB EPX-SURGE-T123 is designed to provide combined Type 1, Type 2 and Type 3 surge protection, helping limit potentially damaging voltage transients within compatible ABB Protecta Power distribution installations.

Type 1 surge protection is intended to handle high-energy lightning impulse currents, while Type 2 protection limits transient overvoltages associated with induced lightning effects and electrical switching. Type 3 protection provides an additional level of voltage limitation, particularly relevant to the protection of sensitive electrical and electronic equipment. The effectiveness of the complete installation depends on correct SPD selection, coordination, earthing and connection arrangements.

By incorporating surge protection into the ABB Protecta Power distribution system, electrical contractors and panel builders can develop coordinated low-voltage distribution installations with enhanced protection against transient electrical disturbances. The EPX-SURGE-T123 is particularly relevant where the electrical installation design specifies a combined Type 1+2+3 surge protective arrangement.
