Mechanical Time Switches

120 VAC; SPDT switch - Carryover of up to 16 hours to maintain accurate load control in the event of power failure - Carryover automatically rewinds when power resumes - One hour of rewinding time for every two hours of power outage - Separate clock motor terminals for switching circuits not on line voltage

Intermatic T7401BR 4PST 125-Volt 7-Day Mechanical Time Switch with Nema 3 Steel Outdoor Cover

This Intermatic T7401BC 7-day dial time switch provides a different 'ON/OFF' program for each day of the week. The time switch also allows 4 pole single throw and 4 pole (2NO/2NC) switching. This time switch provides true 7-day load control with minimum ON and minimum OFF times of 3-1/2 hours. This time switch also provides a carryover of 16 hours minimum to maintain accurate load control even during power failure. When power resumes, the carryover automatically rewinds itself and only 1 hour is required to rewind the carryover for each 2 hours of outage.

This Intermatic T7402B steel case 7-day dial time switch provides a different 'ON/OFF' program for each day of the week. The time switch also allows 4 pole single throw and 4 pole (2NO/2NC) switching. This time switch provides true 7-day load control with minimum ON and minimum OFF times of 3-1/2 hours.

The Intermatic DTAV40E2 is an electronic auto voltage defrost timer by Grasslin. This model is designed for food processing facilities, food equipment, commercial refrigeration systems, blast chillers, free standing coolers and other equipment. This unit is used for electric, air or hot gas defrost systems where timer terminates the defrost; it automatically adjusts voltages between 120 and 240 VAC. It features a rechargeable battery backup and 24Hour/7Day flexible scheduling. The Intermatic DTAV40E2 has a type 3R rainproof plastic enclosure which ensures long life.

The DTAV40IM grasslin by intermatic defrost control is field adjustable for 120V or 240V operation and shall have defrost initiation times settable to the quarter hour via captive trippers at 15 minute intervals. The relay output is 40A resistive, 2Hp at 250Vac. Defrost terminations are completed by time and a remote temperature or pressure switch. The defrost timer is housed in a type 1 indoor metal enclosure. Synchronous timer type, temp rating -4 degrees f to 104 degrees f (-20 degrees Celsius to 40 degrees Celsius). electrical life: 50,000 operations at full load.

The DTAV40M grasslin by intermatic auto voltage defrost timer mechanism is applicable to air defrost (compressor shutdown) and electric or hot gas defrost systems where the defrost is terminated by the timer. If the coil is frost free, the timers can also be terminated by temperature or pressure switches before the programmed defrost termination time has been reached. The time termination functions as a fail-safe and terminates the defrost cycle if the temperature or pressure switch fails to do so. The relay output is 40A resistive, 2Hp at 250Vac. Synchronous timer type, temp rating -4 degrees f to 104 degrees f (-20 degrees Celsius to 40 degrees Celsius). electrical life: 50,000 operations at full load.

The DTAV40Q grasslin by intermatic auto voltage defrost timer is applicable to air defrost (compressor shutdown) and electric or hot gas defrost systems where the defrost is terminated by the timer. If the coil is frost free, the timers can also be terminated by temperature or pressure switches before the programmed defrost termination time has been reached. The time termination functions as a fail-safe and terminates the defrost cycle if the temperature or pressure switch fails to do so. The defrost timer is housed in a type 3R outdoor plastic enclosure. The relay output is 40A resistive, 2Hp at 250Vac. Quartz timer type, temp rating -4 degrees f to 104 degrees f (-20 degrees Celsius to 40 degrees Celsius).

The Intermatic DTAV40QM is an electromechanical quartz defrost timer. This model automatically adjusts voltages between 120 and 240 VAC. Defrost cycles are programmed independently in 15minute intervals. This defrost timer features a type 3R outdoor plastic enclosure which ensures long life. Also, it has an LED indicators for refrigeration and defrost cycles.

The Intermatic DTAV40VM is an auto voltage defrost timer with voltage monitoring and short cycle delay. This model is designed to protect commercial freezers and refrigeration coolers from damaging short cycling, voltage drops and brownouts. This timer automatically adjusts voltages between 120 and 240 VAC. It features a realtime clock face and LED indicators. The Intermatic DTAV40VM has a UL type 3R rainproof enclosure which ensures long life.

The Intermatic DTB is a surface mount OEM replacement bracket. This model is specifically designed for use with defrost timers in refrigeration panels.

The Grässlin DTAV40 Series Auto Voltage Defrost Timer is applicable to air defrost (compressor shutdown) and electric or hot gas defrost systems where the defrost is terminated by the timer. If the coil is frost free, the timers can also be terminated by temperature or pressure switches before the programmed defrost termination time has been reached. The time termination functions as a fail-safe and terminates the defrost cycle if the temperature or pressure switch fails to do so.
