Abb THQL2145 Double Pole Circuit Breaker 45A 120/240V

Product Description

The ABB THQL2145 is a double pole, plug-in circuit breaker rated for 45 amps at 120/240 volts with a 10,000 amp interrupting capacity (10kA IC). It is designed for use in residential and light commercial load centers to provide overcurrent and short-circuit protection on two-pole branch circuits. Licensed electricians install this breaker as part of new panel work, service upgrades, or branch circuit additions. The 10kA interrupting rating meets the fault-current requirements of most residential and light commercial applications, making it a reliable choice for standard panel installations.

This breaker is suited for residential and light commercial applications where a two-pole, 45-amp branch circuit is required. Typical uses include HVAC equipment circuits, electric water heaters, dryers, and similar double-pole loads. Its plug-in design allows installation in load centers that accept the THQL breaker series.

Key Features

• 45-amp rating for double-pole branch circuit protection
• 120/240-volt operating voltage for standard residential and light commercial panels
• 10kA interrupting capacity for reliable fault-current protection
• Plug-in design for compatible load center installation
• Two-pole configuration protects both legs of a 240-volt circuit

Compatibility

Designed as a plug-in style replacement breaker for load centers compatible with the THQL breaker series. Verify panel acceptance of the THQL form factor before installation.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and all applicable local codes. Shut off the main breaker and verify the panel is de-energized before handling any breaker or bus connections. Confirm that the load center accepts the THQL plug-in form factor and that the panel bus rating supports the intended circuit load. Do not exceed the breaker ampere rating for the connected circuit conductors.
