017-502766 – Pressure switch, RT1A Danfoss

Danfoss RT1A Pressure Switch | -0.5 to 7.0 bar | Manual Reset (Max.)

Product Description:

The Danfoss RT1A (017-502766) is engineered for high-stakes industrial applications across the UAE where safety and manual intervention are required. Unlike standard switches, this model includes a Manual Reset (Max.) feature, ensuring that if the pressure exceeds the set limit, the system stays locked out until a technician manually inspects and resets the device. With a regulating range of -0.5 to 7.0 bar, it is perfectly suited for monitoring suction pressure or low-side liquid pressure in Dubai’s heavy-duty chillers. Its IP66-rated enclosure and robust SPDT contact system make it highly resistant to the vibration, humidity, and intense heat characteristic of UAE industrial sites and maritime engine rooms.

Key Features & Benefits:

• Enhanced Safety Manual Reset: Prevents automatic restarting of the system after a high-pressure event, vital for protecting UAE industrial equipment.
• Industrial Durability: Built to withstand harsh environments with an IP66 rating, ideal for the dust and coastal salt air of the UAE.
• Wide Compatibility: The “A” designation confirms suitability for ammonia (NH3) and fluorinated refrigerants, offering versatility for UAE cold chain projects.
• Replaceable Contact System: Allows for easy maintenance of electrical components without replacing the entire unit, saving costs for UAE operators.
• Precise Pressure Control: Features a high-visibility scale and high-repeatability mechanism for accurate pressure monitoring in Dubai.
