Bosta – Contactor Relay CJX9B-25S/D 220–240 V AC for Eco 12 Heat Pump

This is the genuine OEM replacement contactor relay (model CJX9B-25S/D) for the Bosta Eco 12 heat pump. A magnetic AC contactor, it acts as the main power-switching device inside the heat pump’s electrical circuit, controlling the high-current load of the compressor circuit by opening and closing in response to the unit’s control signals. Replacing a worn or failed contactor restores correct start/stop operation of the heat pump.

Funkciók és működés

The CJX9B-25S/D is a single-phase magnetic contactor designed for AC 50/60 Hz circuits with a rated coil voltage of 220–240 V. It controls the main power circuit of the heat pump compressor, switching the high-current load on and off in response to low-current control signals from the unit’s controller. A failed or worn contactor is a common cause of a heat pump that fails to start or runs intermittently.

Kompatibilitás

This part is the factory-specified contactor relay for the Bosta Eco 12 heat pump range. Always verify your unit’s model number and existing contactor type before ordering. This relay is not a universal spare — it is matched to the Eco 12’s electrical specification and should only be used as a like-for-like replacement in that platform.

Telepítés

Replacing a contactor relay involves working inside a live electrical enclosure. Always isolate the heat pump at the mains breaker before beginning work, and photograph all wiring connections before removal to ensure correct reinstallation. This task is recommended for a qualified electrician or a certified pool/heat-pump technician.
