Abb THQB1160 Circuit Breaker 60 Amp 10ka 1 Pole

Product Description

The ABB THQB1160 is a single-pole miniature circuit breaker (MCB) rated at 60 amps with a 10kA interrupt capacity. It provides overcurrent and short-circuit protection for branch circuits in residential and light commercial electrical panels. The THQB series is a bolt-on style breaker designed for installation in compatible load centers and distribution panels. Licensed electricians install this device during new construction, panel upgrades, and circuit additions where reliable overcurrent protection is required to meet NEC requirements.

The THQB1160 is suited for single-pole, 120-volt branch circuit applications in residential and light commercial settings. Typical installations include dedicated appliance circuits, lighting branch circuits, and general-purpose outlets. The bolt-on design ensures a secure, low-resistance connection to the bus bar, making it appropriate for applications where vibration or thermal cycling could loosen a plug-in style breaker.

Key Features

• 60-amp continuous current rating for branch circuit overcurrent protection
• 10kA interrupt rating handles high fault-current events without breaker failure
• Single-pole design for 120-volt branch circuits
• Bolt-on mounting for secure, low-resistance bus bar connection
• THQB series form factor for use in compatible ABB and GE-style load centers

Compatibility

Designed as an OEM-style replacement or new-install bolt-on circuit breaker for compatible THQB-series load centers and distribution panels accepting 1-inch, single-pole bolt-on breakers.

Installation Notes

Installation must be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. Always de-energize the panel and verify absence of voltage with a calibrated meter before handling any breaker or bus bar connection. Confirm the load center bus bar accepts bolt-on style THQB-series breakers before installation. Torque all line and load terminations to the values specified on the breaker label or panel documentation.
