Intermatic 102 Mechanical Time Switch 208-277 Vac Spst

Product DescriptionThe INTERMATIC 102 is a 24-hour mechanical time switch designed for indoor installations in a metal enclosure. It operates on 208-277 VAC at 60 Hz and uses a single-pole, single-throw (SPST) switching configuration. Built for heavy-duty commercial and industrial electrical control, the 102 handles loads up to 40 amps per pole and supports up to 12 ON/OFF switching operations per day. A built-in manual override switch allows technicians to bypass the timer for testing or temporary load control without removing the unit from service. Licensed electricians and electrical contractors are the primary installers of this device.The INTERMATIC 102 is suited for controlling lighting circuits, HVAC equipment, pumps, and other motor or resistive loads in commercial, industrial, and residential settings. Its metal enclosure provides durable protection in indoor environments. The 1-hour interval scheduling resolution makes it appropriate for applications where precise daily on/off cycling is required, such as exterior lighting control, sign lighting, and equipment run-time scheduling.Key FeaturesHandles electrical loads up to 40 amps per poleSupports up to 12 ON/OFF operations per 24-hour periodSPST switching configuration for single-circuit controlManual override switch for bypassing the timer during testing or temporary operationIndoor-rated metal enclosure for durable, protected installationOperates at 208-277 VAC, 60 Hz compatible with common commercial voltage rangesCompatibilityDesigned as an OEM-style replacement or direct-install mechanical time switch for single-circuit lighting, HVAC, and motor load control applications requiring 208-277 VAC operation with SPST switching in an indoor metal enclosure.Installation NotesInstallation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Disconnect and lock out power to the circuit before wiring the time switch. Verify that the load current does not exceed the 40-amp-per-pole rating before energizing. The manual override should be tested after installation to confirm proper bypass function.Technical SpecificationsVoltage: 208-277 VACFrequency: 60 HzSwitch Type: SPSTLoad Capacity: 40 amps per poleMaximum Daily Operations: 12 ON/OFF cycles per dayInterval Resolution: 1 hourEnclosure Type: Indoor metalUPC: 078275102217Standard InformationBrand: INTERMATICManufacturer Part Number: 102
