P70LA-2C Single Pole Dual Pressure Control for Ammonia

P70la-2c single pole dual pressure control for ammonia this p70 series of dual pressure controls employs a spst switch, that is opened when either high pressure or low pressure beyond the control settings is sensed at the controls two bellows sensing elements. the load carrying contacts provide direct control of ac motors within the control's rating. these controls provide close high-open low (low pressure) or open high-close low (high pressure) contact action.
