Wylex NHXS1B25 1 Module SP+SN Miniature Type B RCBO 25A 6kA 30mA

Wylex NHXS1B25 25A 6kA 30mA SP+SN reduced height Type B RCBO for domestic and similar installations are compatible with NM Amendment3 all-metal consumer units which are compliant with the new 18th Edition wiring regulations.

The RCBO combines the overcurrent functions of an MCB with the earth fault functions of an RCD in a single unit.

Wylex NHXS1B25 miniature RCBO provides more wiring space in the enclosure for the installer making the whole installation process easier and quicker. During installation, resistance testing live and neutral conductors do not have to be disconnected.

Now with an increased level of safety these RCBOs include switched neutral as standard. A faulty or damaged circuit is fully isolated by disconnecting the live and neutral conductors. Healthy circuits remain in service, only the faulty circuit is switched off. This avoids danger and prevents inconvenience in the event of a fault (now required by regulation 314.1).

The Wylex NHXS1B25 manufactured to BS EN 61009-1 and BS IEC 1009-2-2 which has a positive indication for On or Off. The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate.
