Eaton siemens-q240 40A 2-pole Circuit Breaker

Product Description

The EATON siemens-q240 is a Type QP/MP molded case circuit breaker designed for residential and light commercial electrical panels. Rated at 40 amps and 120/240 volts AC, it provides two-pole overcurrent protection with a thermal magnetic trip mechanism that responds to both sustained overloads and short-circuit faults. The 10 kA interrupt rating handles fault currents common in residential service panels. The INSTA-WIRE feature simplifies conductor termination during installation, reducing setup time for electricians working in load centers.

This breaker is suited for 120/240 VAC branch circuit applications in residential and light commercial load centers. Typical applications include protecting double-pole branch circuits serving appliances such as electric dryers, ranges, HVAC equipment, water heaters, and sub-panels. It is installed by licensed electricians during new construction, panel upgrades, or branch circuit replacement work.

Key Features

• 40-amp, 2-pole configuration for 240-volt branch circuit protection
• Thermal magnetic trip responds to overloads and short-circuit faults
• 10 kA interrupt rating suitable for residential panel fault levels
• INSTA-WIRE termination design speeds conductor landing
• Type QP/MP molded case construction
• Rated 120/240 VAC for compatibility with standard residential service voltage

Compatibility

Designed as an OEM-style replacement double-pole circuit breaker for residential and light commercial load centers accepting Type QP or MP breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with NFPA 70 (NEC) requirements. De-energize the panel at the utility disconnect or main breaker before handling any load center components. Verify the panel accepts Type QP/MP breakers before installation. Do not exceed the breaker's 40-amp and 10 kA interrupt ratings for the intended branch circuit.
