Allen Bradley Type A RCD Switch, 40A Current Rating, 300mA Trip Sensitivity - 1492-RCDA4C40S

Protect your electrical system from earth faults with this residual current device (RCD) switch from Rockwell Automation's Allen Bradley range. It has type A tripping characteristics, which means it instantly cuts power when the current flowing to the circuit is 2 to 3 times its rated current. This helps prevent damage to your equipment and keeps you safe from electric shocks. Thanks to its compact dimensions of 88 (height) x 70 (width) x 67mm (depth), this unit is suitable for installation in areas with limited space. You'll commonly find it used with general wiring setups in domestic and commercial buildings.

• Housing has an IP4X (ingress protection) rating for protection against objects larger than 1mm in size

• Mechanical lifespan of 20,000 operations for long-lasting performance

• Impulse withstand voltage rating of 4kV to handle sudden power surges

Standards and Certifications

• RoHS (Restriction of Hazardous Substances)

• IEC (International Electrotechnical Commission)

Can I use this RCD switch in hot environments?

Thanks to its wide operating temperature range of -25°C to +55°C, you can use this RCD switch in both extremely hot and cold environments.
