ALCO Emerson TS1-A2A Temperature Control Switch, -30 to +15°C Range, 2m Capillary Bulb, SPDT, Adjustable Differential, IP44, Original Anti-Freeze Switch for HVAC & Chillers

ALCO Emerson TS1-A2A Temperature Control Switch, -30 to +15°C Range, 2m Capillary Bulb, SPDT, Adjustable Differential, IP44, Original Anti-Freeze Switch for HVAC & Chillers

The ALCO Emerson TS1-A2A is an original, high-precision temperature control switch engineered for critical applications in HVAC systems, cold storage units, and chillers, particularly for anti-freeze protection. This robust thermostat features an adjustable temperature range of -30 to +15°C and a 2-meter capillary tube with a temperature bulb for accurate remote sensing. Designed for reliability, the TS1-A2A offers chatter-resistant SPDT (Single Pole Double Throw) contacts with high operational and locked rotor current ratings, ensuring stable and safe control of refrigeration and air conditioning circuits. Its durable construction and IP44 protection (without off-switch) make it suitable for various industrial environments.
