Why Choose the ABB RC B Type x XT5 4p?
The ABB 1SDA118008R1 is a Type B residual-current release designed for compatible ABB SACE Tmax XT5 four-pole circuit breakers. It extends the protection capability of the associated XT5 assembly by providing residual-current protection for applications requiring Type B detection characteristics.
Type B residual-current protection is intended for circuits where residual currents can include AC, pulsating DC and smooth DC components. This makes the accessory particularly relevant to installations containing power-electronic equipment that can produce residual-current waveforms beyond those addressed by basic AC residual-current protection.
Designed specifically for a four-pole XT5 configuration, the 1SDA118008R1 integrates with the compatible ABB Tmax XT platform as a dedicated residual-current protection accessory. Its purpose-built design supports coordinated protection in industrial and commercial low-voltage distribution systems.

Type B Residual-Current Protection for Tmax XT5
Modern electrical systems increasingly incorporate variable-speed drives, converters, rectifiers and other power-electronic equipment. These loads can generate residual currents with DC components, making the selection of the appropriate residual-current protection technology an important part of system design.
The ABB 1SDA118008R1 provides Type B residual-current protection for a compatible four-pole Tmax XT5 assembly. This allows the circuit-breaker system to address residual-current conditions associated with applications where both alternating and DC residual-current components may occur.
Typical Applications
- ABB SACE Tmax XT5 four-pole circuit-breaker assemblies.
- Industrial low-voltage distribution systems.
- Power-electronic equipment installations.
- Variable-speed drive and converter-fed systems.
- Commercial and infrastructure switchboards.
- Circuits requiring Type B residual-current protection.
