Allen Bradley Type A Residual Current Device Switch, 40A Current Rating, 100mA Trip Sensitivity - 1492-RCDA4B40
Safely detect problems in your electrical circuits with this residual current device (RCD) switch from Rockwell Automation's Allen Bradley range. It automatically disconnects a circuit's conductors when it breaks, minimising the risk of shocks and electrical fires. The switch's instantaneous break time ensures a fast response for a high level of workplace safety. Thanks to its broad operating temperature range of -25°C to +55°C, it's suitable for use in demanding environments.
• Type A breaker is compatible with AC or DC power for versatile use
• Toggle switch reset actuator for a simple reset after tripping
• Designed for fast-clip DIN rail mounting to save time and effort during installation
• Long mechanical lifespan of 20,000 operations for long-lasting performance

What kinds of faults cause an RCD to trip?
An RCD detects a dangerously high current in your circuit and trips to prevent the current from causing damage. The most common causes of a high current include loose electrical connections, damaged or faulty wiring, adverse weather conditions and moisture in the circuit or a connected appliance.
