Allen Bradley RCD, 10kA Breaking Capacity, DIN Rail Mounting - 1492-RCDA4D40
To protect industrial equipment against earth leakages, use this RCD from Rockwell Automation's Allen Bradley range. It works together with an MCB to safeguard people from electric shocks and machinery from short circuits and overloads. This helps to keep your work environment safe and also reduces time spent on equipment maintenance and repair. For an extended service life in harsh operating conditions, the unit has a mechanical endurance rating of up to 20, 000 operations. For at-a-glance diagnostics, there's an indicator window that lets you quickly see whether the device is on or off.
Dual terminals for convenient and secure connection of two wires
Wide operating temperature range between -25°C and +55°C, making it suitable to use in demanding settings
Compact dimensions of 70 (L) x 88 (W) x 75mm (D) help you maximise circuit-board packing efficiency
Snaps onto a DIN rail for quick and tool-free mounting and dismounting
