1SDA100405R1 ABB XT5N 630 Ekip Dip LSIG 630A 4-Pole Fixed MCCB with Front Terminals

Why Choose the ABB XT5N 630 Ekip Dip LSIG 630A 4-Pole MCCB?

The ABB XT5N 630 Ekip Dip LSIG, manufacturer order code 1SDA100405R1, is a high-performance 630 A four-pole moulded case circuit breaker (MCCB) designed for reliable circuit protection in low-voltage electrical distribution systems. Part of ABB's SACE Tmax XT5 range, this industrial circuit breaker combines high-current switching capability with an electronic trip unit, fixed mounting and front terminal connections.

Equipped with an Ekip Dip LSIG electronic trip unit, the XT5N 630 provides four essential 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 configure protection settings and coordinate the breaker with other protective devices within a distribution system.

The 630 A rated current makes the ABB 1SDA100405R1 suitable for substantial industrial and commercial power distribution circuits. Its four-pole configuration supports appropriately designed three-phase electrical systems requiring switching of an additional conductor, commonly the neutral.

ABB identifies this exact configuration as XT5N 630 Ekip Dip LSIG In=630 4p F F. The N breaking-capacity version provides a rated service short-circuit breaking capacity of 36 kA at 415 V AC, while the fixed mounting arrangement and front terminals support integration into compatible electrical switchboards and distribution panels.

Advanced 630A Ekip Dip LSIG Electronic Circuit Protection

The ABB XT5N 630 Ekip Dip LSIG is designed to provide dependable protection for high-current low-voltage electrical distribution circuits. Unlike a conventional switch disconnector, this 630 A MCCB automatically interrupts the circuit when its electronic protection system detects fault conditions exceeding the configured thresholds.

The long-time (L) protection function responds to sustained overloads that could otherwise cause excessive conductor heating or equipment damage. Its adjustable settings allow electrical engineers to coordinate the protection characteristic with the design current and current-carrying capacity of the protected circuit.

The short-time (S) protection function provides delayed short-circuit protection, where configured, helping support discrimination between upstream and downstream protective devices. This is particularly valuable in industrial distribution systems where maintaining continuity of supply to unaffected circuits is important. Selectivity must be verified using ABB's published protection curves and the prospective fault-current levels.

The instantaneous (I) protection function responds rapidly to severe short-circuit conditions, while the ground-fault (G) protection function provides an additional protective characteristic for suitable earthing arrangements. The ground-fault function must be configured according to the installation's protection design and should not be confused with a dedicated residual-current device.

The four-pole construction is suitable for appropriately designed three-phase systems where an additional conductor, commonly the neutral, must also be switched. Neutral protection settings and switching requirements depend on the earthing arrangement and applicable electrical regulations.

The fixed mounting arrangement with front terminals is intended for permanent installation in compatible electrical panels and switchboards. The breaker uses a manual toggle operating mechanism and can be equipped with compatible accessories where additional functions are required. The device itself is rated IP20, so suitable panel construction and installation measures must provide the environmental protection required by the installation.

Voltage-Dependent Short-Circuit Breaking Capacity

The ABB XT5N 630 belongs to the N breaking-capacity class within the SACE Tmax XT5 family. Its short-circuit breaking performance depends on the operating voltage, making it essential to verify the electrical characteristics of the installation before selecting the breaker.

For this configuration, published rated service short-circuit breaking capacities (Ics) include 70 kA at 230 V AC, 36 kA at 415 V AC, 25 kA at 500 V AC and 20 kA at 690 V AC. These values must not be applied interchangeably across different voltages.

The rated service breaking capacity (Ics) and ultimate breaking capacity (Icu) are distinct technical characteristics. Electrical designers must confirm that the selected circuit breaker provides suitable short-circuit protection for the prospective fault current at its installation point and coordinate it with upstream and downstream equipment.

With a 1000 V rated insulation voltage, 8 kV rated impulse withstand voltage and 690 V AC rated operational voltage, the XT5N 630 is intended for a broad range of industrial low-voltage distribution applications. Final selection must always account for the installation environment, protection settings, conductor connections and applicable standards.
