Q120H00S01 - 20Amp Circuit Breaker

Q120H00S01 - 20Amp Circuit Breaker

The Q120H00S01 is a 20-amp, single-pole Type QPH circuit breaker with a built-in 120 VAC shunt trip. It's a practical choice when you need standard circuit protection and the ability to trip the breaker remotely via a compatible control circuit. Rated 22kA at 120VAC, this breaker also features a plug-in connection, HACR rating, and a 40°C ambient rating. If you're replacing an existing breaker, the details matter here. Matching the full Q120H00S01 part number helps ensure you're getting the correct pole configuration, amperage, interrupting rating, and shunt-trip voltage, rather than simply another 20A breaker that looks similar.

Key Features and Benefits

• 20A, single-pole configuration for compatible 120VAC applications.
• A 120VAC shunt trip provides a way to trip the breaker from a remote control circuit electrically.
• 22kA A.I.C. rating at 120VAC for applications requiring this interrupting capacity.
• Plug-in design for use with compatible electrical distribution equipment.
• HACR-rated, an important consideration for qualifying heating, air-conditioning, and refrigeration applications.
• 40°C ambient rating provides another key specification when matching the breaker to the application.
• Compact dimensions of 2.88 inches high, 2.00 inches wide, and 2.56 inches deep.

Material Compliance and Certifications

• The Q120H00S01 is HACR-rated based on the available product specifications. This rating is relevant when the breaker is being considered for qualifying heating, air-conditioning, or refrigeration equipment.
• For projects that have specific requirements for UL listings, environmental standards, material declarations, or other certifications, those details should be confirmed using the markings and documentation for the exact breaker being installed. This is especially important when compliance requirements are part of a project specification or inspection.

Where It Works Best

• The Q120H00S01 is best suited for compatible electrical distribution applications that require a 20A, 1-pole QPH plug-in breaker with a 120VAC shunt trip. The shunt trip is what makes this model a little different from an ordinary branch circuit breaker. It allows an external control circuit to initiate a trip, which can be useful when remote interruption of the circuit is required as part of the electrical design.
• This breaker may be used in compatible branch-circuit, HVAC, commercial electrical, facility maintenance, and control applications, provided the equipment and electrical requirements match its specifications.
• Already have a Q120H00S01 that needs replacing? Don't match on amperage alone. Check the complete part number, QPH type, 1-pole configuration, 20A rating, 22kA rating at 120VAC, plug-in connection, and 120VAC shunt trip. Those details help distinguish this breaker from other models that may appear similar but aren't configured the same way.
