ALCO PS3-B6S Adjustable Pressure Switch, 21.5 bar 312 psig, SPDT, High-Pressure, Refrigeration/HVAC, PCN 0715589

ALCO PS3-B6S Adjustable Pressure Switch - High Pressure SPDT, Refrigeration/HVAC (PCN 0715589)

The ALCO PS3-B6S pressure switch, identified by PCN 0715589, is a robust and highly reliable adjustable high-pressure control device specifically engineered for demanding safety and operational oversight within critical refrigeration and HVAC systems. This model is designed to monitor and respond to upper pressure limits, featuring a customizable setpoint of 21.5 bar (312 psig), with predefined pressure switch (PS) at 43 bar (6200 psig) and pressure trip (PT) at 48 bar (695 psig) capabilities. This ensures comprehensive protection for compressors and other sensitive system components against potentially damaging overpressure conditions. Employing a Single Pole Double Throw (SPDT) contact configuration, the PS3-B6S offers versatile electrical control, allowing for the precise immediate activation or deactivation of associated system elements, such as compressor shutdowns, alarm signals, or cooling fans, when critical pressure thresholds are breached. It is rated for 6 FLA, 36 LRA at 120/240 VAC, and 3A @ 230V AC15, indicating its suitability for reliable operation in various robust power circuits. Constructed with a durable metallic pressure sensor for enhanced longevity and performance, and designed for a wide operating temperature range from -40°C to an impressive 150°C, this switch is capable of enduring severe environmental conditions. Manufactured in the Czech Republic and compliant with international safety standards (CE and cURus listed, PSH(EN12263)), the PS3-B6S is an indispensable component for maintaining system integrity, ensuring maximum operational safety, and extending the lifespan of valuable equipment in a broad array of industrial and commercial applications.
