The Vulcan Hart 00-421320-00003 "Top, Hot, 480V" is a genuine OEM heated-top assembly for Vulcan Hart commercial cooking equipment, specified for 480 V electrical supply. Buyers in International markets should confirm their site voltage and frequency match the 480 V rating before ordering, because a 480 V/60 Hz part is not a drop-in for a 400/415 V/50 Hz installation.
What is the Vulcan Hart 00-421320-00003 Top, Hot, 480V?
A Vulcan Hart 00-421320-00003 is an OEM replacement heated-top assembly rated for 480 V supply, forming the hot upper section of a Vulcan Hart commercial cooking appliance. It is ordered by part number, not by appliance model alone, so the number on the rating plate is the definitive reference.
Vulcan Hart is a long-established US commercial cooking OEM, and its part numbers follow a structured format (00-xxxxxx-xxxxx). That structure makes cross-checking straightforward: quote the full number, including the suffix, when requesting a price.
Quotable definition
A Vulcan Hart 00-421320-00003 is a genuine OEM "Top, Hot, 480V" assembly — the heated upper section of a Vulcan Hart commercial cooking appliance, rated for 480 V electrical supply and identified by its full OEM part number rather than by appliance model.
How does a 480 V heated top work?
The assembly provides a heated cooking surface or upper cavity section, energised from a 480 V supply. In North American installations 480 V is a standard three-phase commercial voltage; in much of the rest of the world the equivalent equipment runs at 400/415 V, 50 Hz.
Because heating elements and controls are voltage-specific, the 480 V rating is a hard selection criterion, not a preference. A mismatched element will under-perform or fail, and controls may be damaged.
Spec table: 00-421320-00003 at a glance
| Attribute | Value | Notes |
|---|---|---|
| OEM part number | 00-421320-00003 | Quote the full number including suffix |
| Brand | Vulcan Hart | Genuine OEM replacement |
| Description | Top, Hot | Heated upper section assembly |
| Rated supply voltage | 480 V | Confirm against appliance rating plate |
| Frequency context | 60 Hz (480 V markets); 50 Hz variants exist at 400/415 V | Verify before ordering for International sites |
| Supply basis | EXW Singapore | Collection from our Singapore office |
Only the values above are confirmed by the part description. Any additional electrical data — wattage, phase, element resistance — should be requested with your quote and verified against the appliance data plate.
Which companion parts should be replaced at the same time?
Heated-top work rarely happens in isolation. When a top assembly is replaced, the ignition and gas-side components that feed it are usually at end of life too. Vulcan Hart's oven family shares a common parts ecosystem, so it pays to plan the whole job.
- Ignition and flame sensing: Vulcan Hart OEM Replacement Pilot Assembly
- Gas regulation to the burner: Vulcan Hart Replacement Burner Valve
- Circuit protection: Vulcan Hart Replacement Fuse
- Door heat retention: Vulcan Hart Door Latch
- Water treatment on steam-equipped units: Vulcan Hart Water Filter
Selection criteria for International buyers
- Voltage and frequency first. Confirm 480 V and the site frequency (60 Hz vs 50 Hz). Do not assume a 480 V part suits a 400/415 V, 50 Hz site.
- Match the full part number. The suffix matters; a near-identical number can be a different rating.
- Check the appliance rating plate. Serial and model data narrow the correct variant faster than a photo.
- Plan companion parts. Pilot, burner valve and fuse are commonly replaced alongside a heated top.
- Confirm the commercial basis. Goods are offered EXW Singapore; factor collection and onward movement into your landed cost in USD.
Product selection ladder: Vulcan Hart oven spares
The table below arranges representative Vulcan Hart spares from routine consumables up to the heated-top assembly itself, so you can see where 00-421320-00003 sits in a typical maintenance spend.
| Level | Part | Function | Typical replacement trigger |
|---|---|---|---|
| Routine | Vulcan Hart Replacement Fuse | Circuit protection | Repeated nuisance blowing |
| Routine | Vulcan Hart Replacement Knob | Temperature/function adjustment | Worn or cracked knob |
| Wear item | Vulcan Hart Door Latch | Heat retention and safety | Door not sealing |
| Wear item | Vulcan Hart OEM Replacement Pilot Assembly | Ignition and flame sensing | Pilot will not stay lit |
| Gas side | Vulcan Hart Replacement Burner Valve | Gas flow and flame regulation | Poor flame control |
| Major assembly | 00-421320-00003 Top, Hot, 480V | Heated upper section | Element or assembly failure |
Step up the ladder when a routine part fails repeatedly — repeated fuse blowing or a pilot that will not hold often points to a deeper fault in the burner valve or the heated assembly. At that point, quoting the major assembly alongside the wear items is the cheaper route than two separate call-outs.

Frequently asked questions
What is the 00-421320-00003 Top, Hot, 480V used for?
It is the heated upper section assembly for a Vulcan Hart commercial cooking appliance, rated for 480 V supply. It is ordered by OEM part number and should be matched to the appliance rating plate before purchase.
Can I use a 480 V part on a 400/415 V, 50 Hz site in International markets?
No — voltage and frequency must match. A 480 V, 60 Hz assembly is not a drop-in for a 400/415 V, 50 Hz installation. Confirm the site supply and the appliance data plate, then request the correct variant with your quote.
How do I confirm the right Vulcan Hart part number?
Read the full number from the appliance rating plate, including the suffix, and quote it exactly. Send a photo of the plate with your enquiry; the model and serial data narrow the correct variant faster than a description.
Which parts are usually replaced with a heated top?
Pilot assembly, burner valve and fuse are the most common companions, along with the door latch where heat retention is affected. Quoting them together avoids a second collection from Singapore.
How are prices quoted for International buyers?
Prices are quoted in USD, EXW Singapore. Collection is from our Singapore office; onward movement and any import duties are the buyer's responsibility. Ask for a combined quote covering the assembly and companion parts.
Do you supply Vulcan Hart parts not listed in the catalogue?
Yes. The catalogue shows 164 products in related categories, but we supply far more than is listed. Send the part number and we will quote it from documentation.
