Timing Modes: On Delay or Off Delay, convertible. On Delay types can be wired for interval-maintained start or repeat cycle (sequencing using two devices).

Timed and Instantaneous Output Contacts: SPDT or DPDT snap switch. Contacts of each pole must be used on same polarity.

Repeat Accuracy:
Under constant temperature (Per NEMA Standard ICS 5-1993). ±10% to 1 minute max.

Timing Range: Type A: 0.1 second to 1 minute. Type H: 0.15 second to 1 minute.

Reset Time: Type A: On Delay 29 ms, Off Delay 27 ms average. Type H: On Delay 50 ms, Off Delay 70 ms average.

Operating Temperature Range: 20oC to 40oC (68oF to 104oF)

Operating Voltages/Voltage Range:
Type A—6 through 600 volts AC, +10%, -15% of nominal
Type H—6 through 250 volts DC, +10%, -20% of nominal
