Overview

The ABB TNIA225, SKU: TNIA225, is an Insulated Groundable Neutral designed for ABB Tmax XT circuit breaker enclosures. This essential accessory is rated for a maximum of 250A and accommodates copper (Cu) or aluminum (Al) conductors with a wire size range of 1 AWG to 300 kcmil. For 250A applications, the use of copper cable is specifically recommended per manufacturer guidelines. The TNIA225 is crucial for installations requiring ground fault protection, as mandated by electrical codes, and enables the mounting of neutral sensors for advanced ground fault detection within Tmax XT breaker frames (XT1-XT7). It is compatible with the ECBSPDMTGKIT neutral kit, allowing for the connection of Surge Protective Devices (SPDs) to the neutral for enhanced system protection against transient overvoltages. Constructed in the USA, this neutral meets NEMA Type 4/4X standards, ensuring robust watertight and dust-tight performance suitable for harsh industrial and commercial environments. Its insulated design prevents unintended ground faults. The standard package quantity is one unit. The TNIA225 is cUL Listed and suitable for service equipment applications, with short circuit ratings that match the installed breaker for seamless integration. It is indispensable for 3-phase, 4-wire (3P4W) enclosures requiring ground fault protection, including neutral sensors. Distributed by Gross Automation.
