Abb TC10323R 100A 2 Pole Double Throw Transfer Switch

Product Description

The ABB TC10323R is a 100-amp, 2-pole double throw transfer switch rated for NEMA 3R enclosure service. Double throw transfer switches are used to manually or automatically transfer an electrical load between two power sources, typically utility power and a standby generator. The NEMA 3R rating means the enclosure is suitable for outdoor installation, protecting internal components against rain, sleet, and external ice formation. This switch is installed by licensed electricians and is a core component in residential and light commercial backup power systems.

The TC10323R is suited for applications where a reliable, code-compliant means of transferring loads between utility and generator power is required. At 100 amps and 2 poles, it handles single-phase service entrances and subpanels commonly found in residential buildings, small commercial facilities, and outdoor equipment installations. The NEMA 3R-rated enclosure makes it appropriate for exterior mounting on the side of a structure adjacent to the main service panel or generator disconnect.

Key Features

• 100-amp continuous rating for single-phase load transfer applications
• 2-pole configuration handles standard single-phase services
• Double throw design provides positive break-before-make switching between two power sources
• NEMA 3R enclosure rated for outdoor installation in rain and ice conditions
• Supports residential and light commercial backup power system configurations

Compatibility

Designed as an OEM-style transfer switch for use in single-phase electrical systems requiring a 100-amp, 2-pole double throw switching point between utility and standby generator sources.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. De-energize both the utility source and the generator before making any wiring connections to the switch. Verify that the generator output rating is compatible with the switch amperage before completing the installation. Do not connect both power sources simultaneously in a non-transfer configuration.
