ABB THP100 Snap-On Padlocking Handle Lock for THQL Breakers

The ABB THP100 is a snap-on, padlocking handle lock engineered specifically for THQL circuit breakers used in 1-phase load centers. This handle lock snaps directly onto the breaker toggle, giving electricians and facility maintenance staff a fast, tool-free way to secure a breaker in either the ON or OFF position. The padlock itself is not included and must be supplied separately by the installer. Each unit is supplied 1 EA per package, making it easy to stock the correct quantity for a lockout/tagout program or panel retrofit.

Key Features

  • Snap-On Installation: The THP100 snaps directly onto the breaker handle without special tools, allowing quick field installation during panel servicing.
  • Padlockable Design: Once snapped into place, the lock accepts a standard padlock (padlock not included) to physically secure the breaker handle and prevent unauthorized operation.
  • Breaker Compatibility: Purpose-built for ABB THQL breakers, ensuring a proper mechanical fit on the handle profile of this breaker line.
  • 1-Phase Load Center Application: Designed for use on 1-phase load center breakers, supporting residential and light commercial panel configurations.
  • Compact Packaging: Supplied 1 EA per package for straightforward ordering and inventory planning.
  • Low-Profile Hardware: The lock attaches directly to the existing breaker handle rather than requiring a replacement handle, keeping the panel footprint unchanged.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Electrical Panel Lockout/Tagout (LOTO) Procedures
  • Residential and Light Commercial Load Center Servicing
  • Circuit Breaker Security and Tamper Prevention
  • Facility Maintenance and Electrical Safety Compliance
  • Panel Retrofits Requiring Breaker Handle Locking

Why ABB?

ABB is a recognized name in electrical distribution equipment, and the THP100 handle lock reflects the fit-for-purpose engineering electrical contractors expect when securing THQL breakers. By snapping directly onto the existing breaker handle, it gives facility teams a straightforward, code-conscious way to support lockout/tagout practices without modifying the panel. Choosing ABB accessories designed specifically for ABB breaker lines helps ensure proper mechanical fit and reliable long-term performance in both residential and light commercial load centers.

ABB THP100 – Frequently Asked Questions

1) Does the ABB THP100 come with a padlock?
No padlock is included. The THP100 snaps onto the breaker toggle and accepts a standard padlock that you supply. If you're building out a lockout/tagout kit, budget for the padlocks separately, one per breaker you intend to lock.
2) Can the THP100 lock a breaker in the ON position, or only OFF?
Either. The handle lock secures the THQL breaker toggle in the ON or the OFF position, so it works both for lockout/tagout during service and for holding a critical circuit on to prevent someone switching it off.
3) Will the ABB THP100 handle lock work on a molded case circuit breaker, or do I need a different accessory?
The THP100 is built for ABB THQL breakers in 1-phase load centers, snapping onto the plug-in breaker toggle profile. It is not intended for molded case frames. For a molded case breaker, the corresponding accessory is the Eaton Series C molded case circuit breaker handle lock for J-K frames, which is sized to the larger frame handle rather than a load center toggle.
4) Do I need tools or have to replace the breaker handle to install the THP100?
Neither. It snaps directly onto the existing breaker handle, no special tools and no handle replacement. Because nothing about the breaker changes, the panel footprint and deadfront stay as they are, which is why it works for retrofits on panels already in service.
5) What part number do I order for an ABB THQL breaker lockout device?
ABB THP100 is the manufacturer part number for the snap-on padlocking handle lock covering THQL breakers.
6) Is the THP100 suitable for a commercial building panel or just residential?
Both, within limits. It's intended for 1-phase load center breakers, which covers residential and light commercial panels. For larger molded case breakers in a distribution panel, you need a handle lock rated to that frame instead, such as the Eaton GPLK for Series C frames J and K.
7) What is the difference between the ABB THP100 and the Eaton Series C handle lock accessory?
They serve the same lockout/tagout purpose at two different breaker scales. The ABB THP100 snaps tool-free onto a THQL breaker handle in a 1-phase residential or light commercial load center and accepts a standard padlock, which is supplied by the installer. The Eaton unit is a Series C accessory for J and K frame molded case breakers, the larger distribution-equipment class. Match the accessory to the breaker family already in the panel.
8) I am standardizing lockout hardware across a facility with both panelboards and large frame breakers. Can one handle lock cover everything?
No single handle lock spans both. Plan on two line items: the ABB THP100 for THQL breakers in 1-phase load centers, and the Eaton Series C handle lock accessory for J-K frame molded case breakers. Both secure the breaker handle for LOTO procedures, but each is mechanically matched to its own breaker line, so inventory them by panel type.
9) How many handle locks come in a pack of the ABB THP100?
One each per package. Order one THP100 per breaker you plan to lock out, so a panel where you want six circuits lockable takes six units.
