Used Crabtree Polestar 32A Type 3 30mA MCB/RCD

Crabtree Polestar combined miniature circuit breaker and residual-current device (MCB/RCD), with front markings of 32A, Type 3 and 30mA, and a yellow test button.

Type 3 describes the legacy overcurrent trip characteristic; it is not a modern residual-current waveform classification. Exact catalogue number is not confirmed from the supplied photographs. Match the photographs and markings to the existing installation with your electrician.

Eight used units reported in stock. Photographs show a representative unit; cosmetic wear may vary between units.

Condition: used. Previously installed, with cosmetic marks and discolouration visible in the original photographs. The seller reports the breakers are working; no independent test results or certification are supplied.

For selection, inspection and installation by a qualified electrician. Confirm exact board compatibility and suitability before ordering. The legacy trip-type marking is stated as marked, not a claim of compliance with current installation requirements.

Price includes VAT. Sold individually, not as a pack. Postage is available; delivery charges are calculated at checkout under the store’s standard shipping arrangements.
