QBHW1020S - 20 Amp Circuit Breaker

QBHW1020S - 20 Amp Circuit Breaker

Need a QBHW1020S for an existing setup? This is a 20-amp, single-pole thermal-magnetic breaker with bolt-on mounting and a 120VAC shunt trip. It's rated at 22kA at 120VAC and is HACR-rated for applicable heating, air-conditioning, and refrigeration circuits. The thermal magnetic design protects against overloads and short circuits. At the same time, the shunt trip gives you another useful function: the breaker can be tripped electrically from a properly configured external control circuit. Size is 3.41" high, 2.0" wide, and 2.92" deep, and the breaker carries a 40°C rating. If you're replacing one that's already in a panel, check the complete part number first. It's also smart to compare the amperage, pole count, voltage, interrupting rating, mounting style, and shunt-trip voltage.

Key Features and Benefits

• 20-amp, 1-pole design for compatible 120VAC applications.
• 22kA A.I.C. rating at 120VAC for the specified level of fault-current interruption.
• Thermal-magnetic trip mechanism provides overload and short-circuit protection.
• 120VAC shunt trip allows the breaker to be electrically tripped when used with the proper control circuit.
• Bolt-on mounting provides a secure connection in compatible equipment.
• HACR rated for applicable heating, air-conditioning, and refrigeration circuits.
• 40°C rated for the breaker's specified thermal characteristics.
• Measures 3.41" H x 2.0" W x 2.92" D.

Material Compliance and Certifications

• The supplied specifications list the QBHW1020S as HACR-rated at 40 °C. That HACR designation is important when you're working with compatible heating, air-conditioning, or refrigeration equipment that calls for an HACR-rated breaker.
• We don't have documentation in the provided specifications for additional material-compliance designations or certifications, so we're not going to guess at them. If a particular approval or compliance standard matters for your job, check the markings on the breaker and the documentation for the equipment to be installed.
  

Where It Works Best

• The QBHW1020S is intended for compatible applications calling for a 20A, 1-pole bolt-on breaker at 120VAC. It's particularly useful when the system also needs a 120VAC shunt trip, since that feature allows an external control circuit to initiate a trip.
  
• It's also suited to applicable HVAC circuits that specify an HACR-rated breaker. And, of course, if you're replacing an existing QBHW1020S, this part number gives you an important reference point for identifying the breaker you need.
