THQP120 is a 1-pole, 20A, 240V plug-on circuit breaker designed for everyday electrical work. Built for panelboards, load centers, and electrical distribution setups, it delivers reliable overcurrent protection while streamlining retrofit and maintenance tasks. Available from AmpState, this part number is ideal when you need consistency across service cycles.

  • Fast, plug-on installation: snaps onto standard bus systems, accelerating replacement and reducing field wiring complexity.
  • Precise electrical specs: 1 pole, 240V operation with a 20-amp rating provides targeted protection for single-phase circuits in residential and light commercial panels.
  • Stock-consistent part number: THQP120 helps maintain uniform spare inventories across upgrades and service intervals, reducing downtime.
  • Retrofit-ready: ideal for updating aging panels or swapping in a reliable breaker without altering panel configuration.
  • Versatile distribution compatibility: suitable for a range of panelboards and load centers that support plug-on 1P breakers.
  • Support for compatibility checks: if you’re unsure about fit, AmpState can help verify compatibility and ensure the part number matches your panel.

Use cases and scenarios:

  • Replacing a failed 20A circuit in a residential service panel during a retrofit or service upgrade.
  • Maintaining a consistent spare inventory for ongoing electrical distribution projects.
  • Planning maintenance where a fixed part number simplifies procurement and inventory management.

Important considerations:

  • This THQP120 is a 1-pole, 240V circuit breaker. Always verify your panelboard or load center accepts plug-on breakers with the THQP120 form factor and bus type.
  • For compatibility confirmation, message AmpState with your panel details and we’ll help verify fit.
