The ABB XT5N 400 Ekip Dip LSIG, manufacturer order code 1SDA100404R1, is a high-performance 400 A four-pole moulded case circuit breaker (MCCB) designed to protect low-voltage electrical distribution systems against overloads, short circuits and earth faults. Part of ABB's SACE Tmax XT circuit breaker family, this device combines a 400 A frame, electronic protection and fixed front-terminal connections in a compact industrial circuit breaker.
Equipped with an Ekip Dip LSIG electronic trip unit, the XT5N 400 provides four key protection functions: long-time overload protection (L), short-time short-circuit protection (S), instantaneous short-circuit protection (I) and ground-fault protection (G). These functions allow electrical engineers to coordinate protection settings according to the requirements of the connected installation.
The four-pole configuration makes the breaker suitable for appropriately designed three-phase systems incorporating a neutral conductor. Its fixed mounting arrangement and front terminals support integration into industrial distribution boards, switchboards and electrical control panels.
ABB identifies this exact configuration as XT5N 400 Ekip Dip LSIG In=400 4p F F. The N denotes the normal breaking-capacity version within the XT5 range, while the precise short-circuit breaking capacity must be checked at the intended operating voltage using the manufacturer's technical data.
The ABB XT5N 400 Ekip Dip LSIG provides advanced circuit protection for low-voltage distribution systems. Unlike a basic switch disconnector, this MCCB is designed to automatically interrupt fault currents when the electronic trip unit detects conditions exceeding its configured protection thresholds.
The long-time (L) protection function responds to sustained overloads that could otherwise overheat cables or connected equipment. Its adjustable settings allow engineers to align the protection characteristic with the circuit's design current, conductor capacity and operating requirements.
The short-time (S) protection function responds to short-circuit currents with an adjustable delay characteristic, where supported by the selected settings. This is particularly valuable in distribution systems requiring discrimination between upstream and downstream protective devices. Correct coordination must be established using ABB's time-current curves and the available fault-current data.
The instantaneous (I) protection function is intended to interrupt high short-circuit currents rapidly, limiting the duration of severe electrical faults. The ground-fault (G) protection function provides additional protection against specified earth-fault conditions. Its suitability and settings depend on the system earthing arrangement and the wider protective design.
The four-pole construction is relevant to three-phase distribution systems where the neutral conductor also needs to be switched. However, the treatment of the neutral, including any associated protection settings, must be selected according to the supply arrangement and applicable electrical standards.
The fixed front-terminal configuration is designed for installation in electrical panels and switchboards. Engineers must verify available mounting space, conductor or busbar connections, terminal accessories, ventilation and required clearances against the ABB installation documentation.
The breaker belongs to the XT5N 400 range, with the N designation identifying its breaking-capacity class. The actual Icu and Ics short-circuit ratings are voltage-dependent and must be confirmed before specifying the MCCB. The selected breaking capacity must be appropriate for the prospective fault current at the installation point.
