Allen-Bradley 1492-RCD2A25 Residual Current Device Circuit Breaker

Allen-Bradley 1492-RCD2A25 Residual Current Device (RCD) is a two‑pole protective device that interrupts a circuit when leakage current is detected, providing personnel safety from shock and helping protect equipment in industrial panel installations. This 25 A unit is part of Rockwell Automation’s 1492 RCDA/RCD family and is offered in regional variants configured for 110/120 V or 220/240 V AC systems, including a 230 VAC class option in markets that use 230 V. Designed for panel‑mount installation, it works alongside standard circuit protection to detect residual current and rapidly disconnect the circuit, minimizing exposure to fault conditions. The model 1492‑RCD2A25 emphasizes a two‑pole, 25 A configuration and aligns with the RCDA series’ Type A documentation, which covers residual current devices intended for monitoring and interrupting leakage in electrical systems. Typical applications include industrial control panels, machine enclosures, and safety circuits where reliable leakage protection is essential and compatibility with other 1492 RCDA/RCD components is desired. When selecting, verify the regional voltage variant to match your supply and ensure coordination with your existing Rockwell hardware, wiring schemes, and mounting accessories to achieve proper integration within your protection scheme.
