The Wacker Neuson Circuit Breaker is a genuine OEM component designed for the Pureheat Hydronic Heater (Oil Burner), Pureheat Hydronic Heater (Gas Burner), and Hydronic Air Heater (Diesel) series. As a direct OEM replacement, the is manufactured to the exact electrical specifications of the original part, ensuring proper protection for the heater's control circuits. This circuit breaker installs in place of the factory unit with no adaptation needed, making it the most straightforward service option available for these Pureheat heaters.
Key Features
- Correct Trip-Rating for Heater Circuits — Genuine OEM construction ensures this circuit breaker matches the exact current-interruption rating specified for Pureheat hydronic and hydronic air heater electrical systems.
- Drop-In OEM Replacement — Engineered to the original connector and mounting configuration, this breaker slots directly into the existing panel position on compatible Pureheat units.
- Broad Pureheat Compatibility — Verified fitment across the Pureheat Hydronic Heater Oil Burner, Gas Burner, and Hydronic Air Heater Diesel models, covering a wide range of jobsite heating applications.
- Protects Downstream Electrical Components — A properly functioning circuit breaker prevents overcurrent events from reaching sensitive control boards and ignition components, safeguarding the entire heater system.
- Electrical Safety Compliance — Fuel-fired heating equipment demands correctly rated overcurrent protection; using the specified OEM breaker ensures the heater operates within its designed electrical safety parameters.
A circuit breaker acts as the electrical gatekeeper for the heater's control and burner circuits, automatically interrupting power if current exceeds a safe level. In a hydronic or hydronic air heater, this protection is critical — an undersized or failed breaker can expose the control board, pump motor, and ignition components to damaging overcurrent, while a breaker that trips too readily will cause nuisance shutdowns and leave workers without heat. Replacing a worn or tripped breaker with the correct OEM-rated unit restores reliable, safe electrical protection and keeps the heating system operating as designed.
