Wylex NHX Single Module RCBO, B Curve, 30mA Type A, 6kA
Wylex (Electrium) single module RCBOs from the NH/NM/NMX range, combining B curve overcurrent protection and 30mA Type A residual current protection in one device. We hold three models from our own stock in Lincoln: the NHXS1B20 miniature RCBO with switched neutral for Wylex NM and NMX consumer units, and the NHXSBS1B16 and NHXSBS1B20 single pole RCBOs with balcony terminals for Wylex NH boards. Limited quantities; once they are gone we will not restock these codes.
- B curve tripping characteristic, 6kA short-circuit rating to BS EN / IEC 61009-1
- 30mA Type A residual current protection (AC and pulsating DC earth faults). Note: "Type B" in some trade descriptions refers to the B curve, not a Type B RCD
- Single module width, DIN rail mounting, 230V AC 50Hz
- NHXS1B20: 1 pole + switched neutral (2 poles, line and neutral both disconnect), fits Wylex NM and NMX consumer units
- NHXSBS1B16 / NHXSBS1B20: single pole with neutral lead, neutral not switched, balcony terminal position, fits Wylex NH boards
- Terminal capacity 0.75 to 16mm² (solid and stranded), IP20, -5°C to +40°C
What's included
1 x Wylex RCBO in the model selected.

Options
Choose the model from the Model selector. The NHXS1B20 and NHXSBS devices are not interchangeable: check which Wylex board you have (NM/NMX or NH) before ordering, and size the device to the circuit design and cable in line with BS 7671.
Installation and compliance
Must be installed by a competent electrician and the circuit tested and certified in line with BS 7671. Only fit in a compatible Wylex consumer unit or distribution board. A Type A RCBO is suitable for most domestic circuits; check the equipment manufacturer's requirements where a Type B or Type F device is specified (for example some EV chargers and inverter-driven equipment).
Delivery and collection
Free UK delivery on orders over £50, £4.99 on orders under £50. Free collection from our Lincoln unit, usually ready within 24 hours.
