Allen Bradley RCD, 1kA Breaking Capacity, Screw Terminals - 1492-RCDA4B40S

This Allen Bradley RCD from Rockwell Automation detects earth leakages in your electrical circuit and cuts the power supply should conditions become dangerous. Thanks to a trip sensitivity of 100mA, it's suitable for protecting people against electric shocks, as well as safeguarding equipment against short circuits and current overload. A low power loss of 3.2W means you can rely on the device to be energy-efficient. A toggle switch allows you to manually reset the unit after a fault has been detected. Its screw terminals hold wires securely, so there's less need for maintenance and wire tightening.

• Compact dimensions of 70 (L) x 88 (W) x 75mm (D) to maximise circuit-board packing efficiency
• Broad operating temperature range between -25°C and +55°C, making it compatible with harsh environments
• IP4X-rated housing is protected against water spray and objects larger than 1mm
• Mechanical endurance of up to 20,000 operations, for an extended service life
