The rugged 69HBU2 pressure switch is pre-set to kick on at 100psi and turn off at 125psi which is extremely common for climate control applications or fire suppression applications. 69HBU2 includes an unloader line for 1/4" tubing or refrigeration copper. This switch is designed for the demanding requirements of larger, heavy duty commercial compressors. This is a more robust switch than the 69HAU2 and capable of handling larger motor horse poweres.
The 69HBU2 includes a sturdy painted steel case and cover resists the harsh conditions encountered in industrial applications.
