Why Choose the ABB XT5N 630 MA 1SDA100366R1 Circuit Breaker?
The ABB 1SDA100366R1 is a high-performance SACE Tmax XT5N moulded-case circuit breaker (MCCB) designed for motor protection and reliable switching in low-voltage electrical systems. This fixed three-pole circuit breaker features front terminals and an MA magnetic trip unit, providing adjustable instantaneous short-circuit protection for demanding industrial motor circuits.
As part of the advanced ABB SACE Tmax XT series, the XT5N 630 combines robust construction with flexible circuit protection. The MA release is particularly suited to motor protection applications where overload protection is provided separately, while the circuit breaker provides rapid magnetic protection against high short-circuit currents.
With a rated current of 500 A and an adjustable instantaneous magnetic trip range of 3500–6500 A, the XT5N 630 MA is suitable for high-current motor and industrial power applications. The N breaking-capacity version provides an ultimate short-circuit breaking capacity of 36 kA at 415 V AC, while its fixed mounting and front-terminal configuration enable straightforward integration into switchboards and motor control systems.

Reliable Short-Circuit Protection for Industrial Motors
Motor circuits require effective protection against high short-circuit currents while accommodating the elevated starting currents associated with electric motors. The ABB XT5N 630 MA uses an adjustable magnetic release to provide rapid interruption when current exceeds the selected instantaneous protection threshold.
The adjustable 3500–6500 A magnetic setting enables the protection characteristics to be coordinated with the motor and installation. Because the MA release provides magnetic short-circuit protection rather than conventional thermal overload protection, appropriate separate motor overload protection should be incorporated into the overall motor control and protection system.
Typical Applications
- High-current industrial motor protection systems.
- Motor control centres and electrical control panels.
- Large pumps, fans and compressor installations.
- Conveyors and material handling equipment.
- Manufacturing and process machinery.
- Industrial switchboards and power distribution systems.
