Allen Bradley Type A Residual Current Device Switch, 25A Current Rating, 100mA Trip Sensitivity - 1492-RCDA2B25
Protect your circuits from critical faults with this residual current device (RCD) switch from Rockwell Automation's Allen Bradley range. The 2-pole switch automatically trips when it detects dangerously high electrical currents, protecting operators against electric shocks and preventing damage to machinery. An indicator window displays a red colour when the device is on and a green colour when it's off, making it simple to determine its operating status. Thanks to its robust mechanical lifespan of 20, 000 operations, this is a long-lasting choice.
Residual breaking capacity of 1kA and short-circuit breaking capacity of 10kA for protection against current leakages and electrical surges
Toggle switch reset actuator lets you quickly and easily reset the device
Designed for DIN rail mounting with a fast-clip feature for simple and secure installation

When should I use a type A RCD?
A type A RCD is suitable for use in circuits with components that run on either AC or DC power, making it a versatile option. This type of RCD is commonly used to protect inverters and lighting systems.
