The Wacker Neuson Overload Switch 5Hp Motor is a genuine OEM component designed for the HI750 and HI900 series mobile indirect fired air heaters. Sourced directly from Wacker Neuson, this switch meets the exact electrical specifications required for safe and consistent operation of the 5Hp motor circuit. It fits a wide range of HI750 and HI900 configurations including diesel, natural gas, LP, and dual-fuel DGM variants across both standard and skid-mounted setups. When your overload protection is compromised, restoring it with the correct OEM part keeps the heater running within its designed parameters.
Key Features
- Correct Trip Rating for the 5Hp Motor Circuit — Calibrated to the precise overload threshold of the Wacker Neuson 5Hp motor, ensuring the switch trips when it should and holds when it should.
- Genuine OEM Part — Manufactured to Wacker Neuson specification, so electrical characteristics, terminal configuration, and housing dimensions match the original exactly.
- Direct Drop-In Replacement — Terminals and mounting points align with the original switch position, allowing straightforward installation without adapters or rework.
- Broad HI750 and HI900 Series Coverage — Compatible with diesel, natural gas, LP, DGM, and surge brake configurations across both standard and skid-mounted indirect air heater models.
- Protects the Motor from Overcurrent Damage — A functioning overload switch prevents sustained overcurrent from burning out the motor windings; a failed switch leaves the motor unprotected and vulnerable to costly damage.
- Electrical Safety Component — As a primary overcurrent protection device in the heater's motor circuit, using the correct rated switch is essential for safe operation and compliance with the equipment's original electrical design.
The overload switch in a Wacker Neuson indirect air heater monitors the current draw of the 5Hp motor and automatically interrupts the circuit if the motor draws more amperage than its rated limit — protecting the motor from heat buildup and winding damage caused by sustained overload conditions. Without a properly functioning switch, the motor has no automatic protection against overcurrent faults, which can lead to motor failure or, in severe cases, electrical hazards. Replacing a tripped or failed overload switch with the correct OEM-rated component restores that layer of protection and returns the heater to full, safe operation.
