The HP55B6 is a high-quality CYCL-FLEX® reset timer featuring a synchronous motor drive mechanism housed in a standard CYCL-FLEX® plug-in housing. It offers 16 standard time ranges from 5 seconds to 60 hours with knob-adjustable setpoints, a red progress pointer displaying remaining time, and a pilot light indicating motor energization. The timer operates at 240V, 60 Hz with a motor burden of 2.45 VA and clutch burden of 10.5 VA, providing output ratings of 5 amps resistive at 240 VAC. The device features highly visible calibrated dials with 7.85-inch circumference, delayed contact switching (contacts 4-3 and 11-A close at timeout; contacts 4-5 and 11-12 open), and a maximum reset time of 0.5 seconds. With UL, CSA, FM, and RoHS certifications, the HP55B6 is ideal for industrial automation, process control, and equipment sequencing where reliable, repeatable timing intervals are essential.
