Ajax Geyser Control Kit (20A | 25A) – Onesto Contactors

DescriptionAjax Geyser Control Kit with Onesto Modular Contactor (20A | 25A)Smart, safe and efficient control for high-power geysers.Upgrade your electric geyser with intelligent control and maximum safety. The Ajax Geyser Control Kit combines the advanced Ajax WallSwitch with the Onesto modular contactor (20A / 25A options) enabling you to manage high-current geysers seamlessly from anywhere.Standard Ajax WallSwitch relays are not designed to switch heavy loads directly. This kit solves the problem by using the WallSwitch only to control the Schneider contactor’s coil, leaving the contactor to handle the geyser’s high current draw safely.Enjoy smart home convenience without compromising reliability:Remote Control & Scheduling: Switch your geyser on/off via the Ajax app or set automated scenarios.Energy Efficiency: Program heating to match off-peak hours or solar generation.Overload Protection: WallSwitch monitors power and protects against overcurrent, while the contactor switches the load.Simple Installation: DIN-rail mounting and straightforward wiring between WallSwitch and contactor.Whether you want to reduce your electricity bill or automate your daily routine, the Ajax Geyser Control Kit provides the flexibility and safety you need.Why You Need This KitPrevents Ajax WallSwitch overload – WallSwitch is not rated for direct high-current geysers and will trip or shut off.Contactor does the heavy lifting handling the full geyser load reliably and safely.Maintains full smart-home capability with app control, energy data and seamless automations.Protects your system, with built-in current, surge and heat safeguards.ApplicationsRemote geyser controlSmart energy management with solar systemsScheduled heating cyclesSafety interlocks to prevent overloadsSpecificationsAjax WallSwitch:Max Load (Resistive): 3kWVoltage: 230V ACOvercurrent & surge protectionPower consumption monitoringOnesto 18mm DIN Rail Modular Contactor 20A (1P, 1NO, 230V)Current Rating (AC-7a): 20ACurrent Rating (AC-7b): 7AAuxiliary Contact: 1 × NOPoles: 1PCoil Voltage: 230VWidth: 18 mmStandards: IEC/EN 61095Onesto 18mm DIN Rail Modular Contactor 25A (1P, 1NO, 230V)Current Rating (AC-7a): 25ACurrent Rating (AC-7b): 9AAuxiliary Contact: 1 × NOPoles: 1PCoil Voltage: 230VWidth: 18 mmStandards: IEC/EN 61095What’s in the BoxOption 1 – Onesto 20A Contactor1× Ajax WallSwitch (wireless smart relay)1× Ajax DIN-Holder1× Onesto Modular Contactor 20AOption 2 – Onesto 25A Contactor1× Ajax WallSwitch (wireless smart relay)1× Ajax DIN-Holder1× Onesto Modular Contactor 25APlease note: Product images are for reference only and the actual item may differ slightly in appearance.
