ABB FS401 RCCB, 16A, 1P+N Pole, 30mA, Type B

Improve electrical safety with this RCD switch from ABB. The device trips the power to an attached circuit to prevent electric shocks and fires when there's contact with live wires. Integrated input wiring lets you easily snap the component into a plug-in socket, saving you from creating connections. You can conveniently swap it around with other elements, thanks to the modular design. It's a lightweight unit at just 250g and puts minimal strain on assemblies. Simply clip it onto a DIN rail for quick and tool-free installation.

• 230V AC voltage rating makes it compatible with standard electrical circuits
• Instantaneous break time ensures immediate tripping during faults
• Type-B tripping for resistive loads

• Domestic appliances
• Lighting systems
• Uninterruptible power supplies
• Surge suppressors

MCBs typically protect against overcurrent and short circuits, while an RCD detects earth leakages to safeguard against injuries and fires. For complete protection, you should use these devices together.

The device will function without a neutral, but it's not advised, as the testing function may not work. This RCD comes with a neutral connection.
