Put a stop to electrical hazards in your circuit using this RCCB from Eaton. It cuts power to your equipment when it senses an earth leakage, helping to minimise the risk of shock and machine damage. The unit is a cinch to mount, as you can simply clip it onto your DIN rail without the need for any tools. Thanks to its compact dimensions of 45 (L) x 70 (W) x 80mm (H), it's a sure fit for crowded rails. You can use an RCCB like this one to protect medical devices and lighting fixtures.

• Front-facing toggle switch for convenient resetting
• Current rating of 40A for safe use with heavy-duty equipment
• Integrated test button for quick troubleshooting
• Performs reliably at temperatures between -25°C and +60°C for use in harsh environments
• Rated impulse withstand voltage of 4kV means it's protected against powerful spikes

It has a mechanical lifespan of at least 20,000 operations and an electrical lifespan of at least 4000 operations, so it can withstand long-term use.
