Bosch 415-51043-128 Conversion Kit 208V 12kw

Product Description

The BOSCH 415-51043-128 is an electric water heater conversion kit rated at 208 volts and 12 kilowatts (kW). It is designed to convert compatible electric water heaters to a different heating element configuration, allowing the unit to operate at the specified voltage and power output. Licensed plumbers and water heater technicians install this kit during system upgrades or when replacing a water heater that previously operated on a different electrical supply. The kit measures 4.25 inches by 4.25 inches and weighs approximately 2.84 pounds, making it a compact, field-installable assembly.

This conversion kit applies to electric water heater installations where the available supply voltage is 208 volts, common in commercial buildings, multi-family residential properties, and light industrial settings. It is suited for retrofit applications where an existing water heater must be reconfigured to match on-site electrical service. Installers should verify the existing wiring and panel capacity before proceeding with the conversion.

Installation Notes

Installation should be performed by a licensed plumber or qualified water heater technician in accordance with local plumbing and electrical codes. Disconnect electrical power at the breaker and shut off the cold water supply to the heater before beginning work. Verify that the existing electrical circuit is rated to handle the 208-volt, 12 kW load before completing the conversion. Do not energize the unit until the tank is fully filled with water to prevent dry-fire damage to the heating elements.
