Abb THQL2125 2-pole 25A 120/240V Circuit Breaker

Product Description

The ABB THQL2125 is a 2-pole thermal-magnetic circuit breaker rated for 25 amps at 120/240 volts AC with a 10,000-ampere interrupting capacity (AIC). It provides overcurrent and short-circuit protection for residential and light commercial branch circuits. The breaker uses a thermal-magnetic trip mechanism, responding to sustained overloads via the thermal element and to high-fault currents via the magnetic element. Licensed electricians install this breaker during new construction, panel upgrades, or branch circuit replacements. The THQL series is a widely used format in residential load centers, making this a straightforward swap for panels accepting THQL-style breakers.

The THQL2125 is suited for residential and light commercial electrical panels where a 2-pole, 25-amp branch circuit breaker is required. Typical applications include dedicated circuits for HVAC equipment, water heaters, sub-panels, and other double-pole loads requiring 240-volt service. It fits load centers designed to accept THQL-series breakers and complies with standard panel installation practices governed by the National Electrical Code (NEC).

Key Features

• 2-pole design provides double-pole overcurrent protection for 240-volt circuits
• 25-amp continuous rating handles typical HVAC and appliance branch circuits
• 10,000-ampere interrupting capacity (AIC) for fault current protection in residential panels
• 120/240-volt AC rating covers standard residential and light commercial service voltages
• Thermal-magnetic trip mechanism responds to both sustained overloads and instantaneous short-circuit faults

Compatibility

Designed as an OEM-style replacement for residential and light commercial load centers that accept THQL-series 2-pole circuit breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the NEC and all applicable local codes. Always de-energize the panel and verify absence of voltage with a meter before handling breakers or bus connections. Confirm the load center is rated to accept THQL-series breakers before installation. Do not exceed the breaker's 25-amp continuous rating when sizing the protected circuit conductors.
