The Wacker Neuson Circuit Breaker is a genuine OEM component designed for the E3000, E2200, E1100, E3000 ES, and Pureheat series hydronic surface heaters and ground heaters. As a direct OEM replacement, this circuit breaker is manufactured to the exact specification required by Wacker Neuson, ensuring it integrates correctly with the electrical protection system in your heater unit. Compatible across a wide range of configurations — including lift bail, generator-equipped, and temperature-controlled variants — part number covers the full E-series and Pureheat hydronic heater lineup. Keep a spare on hand for fast turnaround during cold-weather concrete curing and ground thawing operations.
Key Features
- Correct Trip Rating for Hydronic Heater Circuits — Matched to the electrical load specifications of the E-series and Pureheat heater systems, ensuring the breaker trips at the right threshold without nuisance trips or under-protection.
- Genuine OEM Part — Sourced directly from Wacker Neuson, this circuit breaker carries the same part number and build standard as the component installed at the factory.
- Broad E-Series and Pureheat Compatibility — Fits E1100, E2200, E3000, E3000 ES, and Pureheat hydronic heater models, including ground heater, hydronic surface heater, lift bail, generator, and temperature-controlled configurations.
- Electrical System Protection — A functioning circuit breaker prevents overcurrent damage to the heater's wiring, controls, and pump components. A failed or incorrectly rated breaker risks both equipment damage and unsafe operating conditions.
- Drop-In Replacement — Installs in the existing breaker position with no rework to the electrical panel or wiring harness, restoring the heater to full operation quickly.
- Critical for Cold-Weather Operations — Hydronic heaters run continuously during concrete curing and ground thawing; a correctly rated circuit breaker is essential to uninterrupted, safe operation in demanding winter jobsite conditions.
A circuit breaker is an automatic electrical protection device that monitors current flow through a circuit and trips — cutting power — if that current exceeds a safe level. In a hydronic heater like the Wacker Neuson E-series or Pureheat units, the circuit breaker safeguards the pump motor, heating elements, and control electronics from damage caused by overloads or short circuits. When a circuit breaker fails or trips repeatedly without resetting, it is typically a sign of either a fault elsewhere in the system or a breaker that has worn beyond its reliable operating range and needs replacement.
