Instantaneous Residual Current Protection for Tmax XT3
Residual current releases monitor an electrical circuit for an imbalance that can indicate current leakage to earth. When the applicable residual current protection threshold is reached, the release works with the circuit breaker to disconnect the circuit, supporting protection of the electrical installation against earth leakage faults.
The ABB RC Inst 1SDA067129R1 provides this functionality for compatible fixed four-pole Tmax XT3 circuit breakers. Its dedicated XT3 design, instantaneous operating characteristic and 85–690 V AC operating range make it suitable for professional industrial and commercial low-voltage distribution assemblies.
Typical Applications
- ABB Tmax XT3 fixed four-pole circuit-breaker installations.
- Industrial low-voltage distribution systems.
- Commercial electrical switchboards.
- Residual current and earth leakage protection.
- Power distribution panels requiring instantaneous residual current protection.
- OEM machinery and industrial electrical assemblies.
