Dixell Relay 30AMP RELAY30

Who it’s for: licensed fridgies, service techs and apprentices who need a reliable 30-amp interposing relay to let Dixell XR-series controllers switch higher loads safely. It’s a simple add-on that keeps jobs tidy and compliant, no worries.

Key Features & Trade Benefits

• 30A contact rating — gives your controller the grunt to switch compressor, fan, or defrost loads via an external relay (less stress on controller outputs, fewer call-backs).
• Interposing relay for XR-series — ideal when the controller’s onboard relay isn’t sized for the load; wire through RELAY30 for safe, stable operation.
• Simple two-stage control — controller drives RELAY30; RELAY30 switches the actual load — bloody good for neat panel layouts.
• Field-serviceable format — straightforward terminals and clear markings make swaps quick when you’re against the clock.
• Broad application — coolrooms, freezers, merchandisers, and HVAC plant where external load switching is required.

Why This Product Matters

Controller relays aren’t always built to handle compressor inrush or defrost heater currents. The RELAY30 acts as your workhorse between the controller and the load, protecting the brains while the muscle does the heavy lifting. Quick anecdote: tech on a steamy Sydney arvo had a cabinet compressor chattering on start. Dropped in an external 30A relay, tidied the wiring, and fair dinkum — system pulled down clean with no more nuisance trips.

Pro Tip

• Match coil/control voltage: wire the relay coil to suit your panel supply or the controller’s output specs. If unsure, check the controller manual and panel drawings.
• Cable management: route away from heater runs and sharp edges; label both the coil feed and switched load so the next tech can fly through service.
• Safety first: isolate and test before you touch — lockout/tagout and follow site procedures.

Compatibility & System Info

Designed as an external 30A interposing relay for Dixell XR-series controllers (e.g., XR20CX/XR60CX) when higher load currents demand an additional switching device. Always confirm load current, inrush, and wiring method in your controller documentation.

Typical Aussie jobsites: hot rooftops in Brisbane or salty coastal air in Sydney. Keep terminations tight, use correct ferrules, and enclose against moisture where needed — she’ll be right.

FAQs

Will RELAY30 work with my XR20CX?
Yes — use it as an external interposing relay when the controlled load exceeds the controller’s onboard relay rating. Always check the XR manual.

What loads can I switch?
Commonly used for compressors, condenser/evaporator fans, or defrost circuits. Confirm actual current (including inrush) and protect the circuit appropriately.

Do I need a potential relay as well?
Different role. A potential relay is for motor starting; RELAY30 is for load switching.

Any safety guidance?
Yes — follow WHS electrical safety practices and isolate before work. See Safe Work Australia guidance below.
