The Ranco O16-R6703 LP HD Series is a low-pressure safety switch used in refrigeration and air conditioning systems. It automatically trips when the circuit pressure is too low, protecting the compressor from malfunctions or vacuum conditions.

Thanks to automatic reset, the device restores system operation without manual intervention when the pressure returns to the correct values. The construction of the HD (Heavy Duty) series guarantees robustness and reliability even in professional and continuous use.
