45A Double Pole Wall Switch with Neon — Full Isolation for Cookers, Showers & High‑Power Appliances
The R30327 is an electrical device designed to provide a simple but effective method for isolating the electrical supply to an appliance such as a cooker, shower, or any other high-power equipment. It is a double-pole (DP), wall-mounted switch with a 45A rating and is housed in a standard 86mm x 86mm (R30) panel. The switch is not an industrial toggle switch or a bulky isolator switch; it is a conventional switch that fits in with the other switches in your house. As a DP switch, it will switch off the live (Ph) and neutral (N) wires simultaneously when it is turned off, providing the necessary complete isolation of the electrical supply for high-power appliances connected to the circuit. The integrated neon indicator will glow to let you know that there is power at the switch, i.e., the circuit is live. The R30327 DP switch is rated for 45A and 250V and uses heavy-duty Φ5.5mm silver contacts. It conforms to the IEC 60669 standard and comes with a 12-year manufacturer’s warranty for residential and commercial installations.
45A Rating with Φ5.5mm Silver Contacts: Another benefit of the 45A DP wall switch is that it uses Φ5.5mm silver alloy contacts, which are more massive than the Φ3.5mm contacts used in a 20A DP switch. Therefore, the Φ5.5mm contacts will handle the continuous high current that may be drawn from an electric cooker, instantaneous shower, or industrial heating appliances. With a maximum load of 11kW at 45A/250V, the R30327 double-pole wall switch is suitable for use with the highest-powered fixed appliances in both residential and light commercial circumstances.
A Wall Switch, Not a Toggle or Isolator Box: In conclusion, although the R30327 has a heavy-duty 45A current rating, it is still a conventional 86mm x 86mm wall switch panel just like every other R30 light switch. The switch mounts flush into the back of a standard British back box and is indistinguishable from other switches. The switch form factor will allow it to be installed in a common multi-gang installation. The familiar rocking motion makes it simple to use for the end user, while the internal double pole mechanism offers full isolation as required by wiring regulations.
Red Copper Bus Bar & Superior Φ5.5mm Contacts
An entirely new level of performance has been achieved in this 45A DP switch. The internal red copper bus bar system will carry the entire 45A across both poles. The most significant improvement over the older 20A version is its use of Φ5.5mm silver alloy contact points — these contact points have nearly 2.5 times the area of those in the 20A version and are capable of handling the increased arc load produced by high‑current switches. Red copper stamped components and bushes further reduce resistance and heat build-up. The mechanism is rated for 10,000 cycles of operation at an entire 45 Amp load. The front plate and base are made from high-strength, imported polycarbonate with good clarity and strength, while an iron plate inside reinforces the assembly and gives it an exceptionally solid and durable appearance when installed.

Where to Specify This 45A Double Pole Wall Switch
Application notes for electricians and contractors specifying a 45A DP switch for cookers, showers, and high‑power fixed appliances.
Application Use Cases
For electric cookers and range ovens, this 45A double pole wall switch provides the mandatory local isolation required by UK wiring regulations — functioning as a dedicated cooker switch or cooker isolator switch. For electric showers and instantaneous water heaters, it serves as a shower switch or shower isolator, allowing complete disconnection for maintenance. In commercial kitchens and light industrial settings, it isolates 45A circuits supplying fryers, steamers, and heating equipment. The 45A rating supports circuits up to approximately 11kW at 240V, covering the vast majority of domestic and light commercial high‑power appliances.
45A DP Switch vs 20A DP Switch — Selecting the Correct Rating
Choose the 20A DP switch for water heaters, air conditioning units, and standard fixed appliances up to approximately 4.8kW. Choose this 45A double pole wall switch for electric cookers, instantaneous showers, and circuits up to 11kW. The key physical difference is the contact size — the 45A version uses Φ5.5mm silver contacts versus Φ3.5mm in the 20A model, engineered to manage the heavier arc loads of high‑current switching. Both share the same 86×86mm panel and R30 aesthetic.
Installation Note
The R30327 mounts into a standard 86×86mm British back box. Terminals are clearly marked for incoming and outgoing live and neutral connections, with a separate earth continuity terminal. The neon indicator is wired internally across the load side. Due to the 45A current, use appropriately sized supply cable — typically 10mm² for cooker circuits and 6mm² to 10mm² for shower circuits depending on the installation length and method. All connections must be torqued securely to handle the full rated current without overheating.
Frequently Asked Questions
What is a 45A DP switch?
A 45A DP switch is a double pole wall switch rated at 45 amps that isolates both live and neutral simultaneously from a single wall plate. The R30327 is a 45A double pole wall switch with a neon indicator — designed as an 86×86mm wall‑mounted panel for electric cookers, showers, and high‑power fixed appliances, not an industrial toggle switch.
What is the difference between a 20A and 45A double pole switch?
The key difference is the current rating and contact size. A 20A DP switch handles circuits up to approximately 4.8kW — suitable for water heaters and air conditioners. A 45A DP switch like the R30327 handles circuits up to 11kW — required for electric cookers and instantaneous showers. Internally, the 45A version uses larger Φ5.5mm silver contacts to manage the heavier current, compared to Φ3.5mm contacts in the 20A model. Both fit the same 86×86mm back box.
What is a cooker switch?
A cooker switch is a wall‑mounted double pole isolator specifically rated for electric cooker circuits. It provides a visible point of isolation where both live and neutral can be disconnected before servicing. The R30327 45A double pole wall switch is a cooker switch — it meets UK wiring regulations for cooker circuit isolation, includes a neon indicator to show when the circuit is live, and fits a standard 86×86mm back box.
Is this 45A DP switch a wall switch panel or an industrial isolator?
The R30327 is a wall‑mounted switch panel — a standard 86×86mm rocker switch that fits a British back box and matches the R30 series aesthetic. It is not a bulky industrial isolator or a toggle switch. Despite its 45A rating, it uses the same PC panel format as every R30 light switch, so it sits flush alongside your other wall fittings.
