Allen Bradley Type A RCD Switch, 40A Current Rating, 30mA Trip Sensitivity - 1492-RCDA4A40
Improve safety in commercial and industrial environments with this residual current device (RCD) switch from Rockwell Automation's Allen Bradley range. The unit monitors a circuit and cuts power when an earth fault occurs, reducing the risk of machine damage and electrical hazards. Its robust thermoplastic housing material is resistant to impact and chemicals, so it's suitable for use in harsh industrial environments. This device has a trip sensitivity of 30mA for a quick response to faults, making it a good choice for use with delicate electrical components.
• Compact dimensions of 88 (height) x 70 (width) x 67mm (depth) for installation in areas where space is limited
• Designed for DIN rail mounting with a fast-clip feature that allows for simple, tool-free installation
• Wide operating temperature range of -25°C to +55°C for use in demanding industrial environments
• Mechanical lifespan of 20,000 operations for long-lasting use
