Cudis 13A 30mA Type A RCD Fused Spur Unit White | SUP

The Cudis 13A 30mA Type A RCD Fused Spur Unit (SUP / SU13P) provides combined fused connection and residual current protection for fixed appliances and dedicated circuits. Designed in a white plastic finish, this RCD fused spur adds an extra layer of safety where local protection is required.

Featuring Type A RCD protection, the unit detects both AC and pulsating DC residual currents. The built-in test button allows quick functional checks, while passive type latching ensures the device does not automatically reset after a power interruption — improving safety for connected equipment.

Conforming to BS 7288:2016 and BS 1363, this RCD fused spur is ideal for protecting boilers, heaters, outdoor equipment, and other fixed loads.
