Temperature Control Switch A110350300-3

High-Precision Thermal Management for 5-Series Excavators

The Hyundai A110350300-3 is a high-precision temperature control switch designed to monitor engine and hydraulic cooling states in your 5-series excavators. By sensing coolant or oil temperature fluctuations, this switch triggers the necessary cooling system responses—such as fan activation—to ensure your engine and hydraulic components remain within their optimal thermal operating range. It is a vital component for preventing thermal degradation and ensuring the longevity of your machine's primary power and hydraulic systems.

1. Technical Specifications

Parameter	Detail
Part Number	A110350300-3
Component Type	Temperature Control Switch (Thermal Sensor)
Primary Function	Monitors fluid temperature and triggers cooling system responses to maintain stable operating temperatures
Compatibility	Specifically engineered for Hyundai 5-series tracked and wheeled excavator configurations

2. Machine Compatibility

Engineered for reliable thermal regulation in mid-sized machinery:

Hyundai Models: R220LC-5, R300LC-5, R210W-5, and related configurations.
System Synergy: Provides the critical data signal for the cooling system, ensuring that the engine does not exceed safe operating temperatures during intensive work cycles.

3. Maintenance & Installation Protocols

Service Interval: Replace as needed upon failure, or if the temperature gauge behaves erratically or fails to trigger cooling fans.
Diagnostic Indicators: Replace if the machine overheats while the cooling fan remains off, if the temperature indicator light on the dash shows a false warning, or if the switch shows signs of internal short-circuiting.
Installation Tip: When replacing the temperature switch, ensure the system is cool to avoid hot fluid spray. Use thread sealant if required to ensure a leak-free fit into the housing, and confirm that the electrical connector is clean and free of corrosion to ensure accurate signal transmission.
