Abb TC10324R Double Throw Safety Switch 200A 2P Nema 3R

Product Description

The ABB TC10324R is a non-fusible, double throw safety switch rated for 200 amps at 120/240 volts in a 2-pole configuration. Housed in a NEMA 3R enclosure, it provides reliable protection against rain and sleet, making it suitable for outdoor installations. Double throw switches are commonly used in emergency generator transfer applications, allowing a circuit to be manually switched between a utility source and a backup power source. Licensed electricians install this switch as part of standby power systems in residential and light commercial settings.

This switch is designed for residential and light commercial applications where a dependable manual transfer mechanism is required. The NEMA 3R enclosure rating makes it appropriate for covered outdoor locations exposed to weather. Typical installations include generator transfer points at service entrances, utility disconnects, and load-side switching for backup power equipment. The non-fusible design means overcurrent protection must be provided upstream by the existing service equipment.

Key Features

• Double throw mechanism for manual transfer between two power sources
• 200-amp continuous current rating at 120/240 volts
• 2-pole configuration for single-phase systems
• NEMA 3R enclosure rated for outdoor, rain-tight installation
• Non-fusible design for use with upstream overcurrent protection

Compatibility

Designed as an OEM-style replacement or direct installation double throw safety switch for residential and light commercial single-phase electrical systems requiring a 200-amp, 2-pole, NEMA 3R non-fusible transfer switch.

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 feed and the generator source before beginning installation or any service work on the switch. Verify that upstream overcurrent protection is properly sized, as this switch does not include internal fusing. Follow the manufacturer wiring diagram for correct line and load terminal connections to prevent backfeed hazards.
