ABB THT104 Snap-On Handle Tie for TQB/TQC/TQL Breakers
The ABB THT104 is a solid, snap-on handle tie engineered for single-pole TQB, TQC, and TQL breakers. It mechanically links adjacent single-pole breaker handles so an electrician can switch multiple single-pole devices on or off together in one motion. Because multi-pole breakers already include an internal common trip, this handle tie is intended strictly for one-pole devices, giving panels built from single-pole breakers the manual on-off convenience of a multi-pole unit without replacing the breakers themselves. It is supplied 1 EA per package for straightforward, panel-by-panel installation.
Key Features
- Model Compatibility: Engineered specifically for single-pole TQB, TQC, and TQL breakers.
- Solid Snap-On Construction: A solid, snap-on design allows quick, secure attachment directly onto the breaker handles without extra tools or hardware.
- Manual On-Off Capability: Ties single-pole breaker handles together so they operate as one, providing coordinated manual switching between one-pole devices.
- Single-Pole Application Only: Intended for use where multi-pole common trip is not already built in, since multi-pole breakers already include internal common trip protection.
- Packaging: Supplied 1 EA for straightforward panel-by-panel installation.
Technical Specifications
- Refer to manufacturer documentation for complete technical specifications.
Typical Applications
- Panelboard and Load Center Wiring
- Ganging Single-Pole Breakers for Coordinated Manual Switching
- Residential and Commercial Electrical Panels
- Multi-Circuit Control on TQB, TQC, and TQL Breaker Panels
- Renovation and New Construction Electrical Work
Why ABB?
ABB engineers breaker accessories like the THT104 handle tie to work precisely with its TQB, TQC, and TQL single-pole breaker lines, ensuring a secure, reliable snap-on fit for coordinated manual switching. For electricians and facility teams standardizing on ABB breaker systems, the THT104 offers a simple, straightforward way to gang single-pole devices for consistent on-off control across a panel, without the cost of swapping in new multi-pole breakers.

ABB THT104 – Frequently Asked Questions
1) Which breakers does the ABB THT104 handle tie fit?
The THT104 snaps onto single-pole ABB TQB, TQC, and TQL breaker handles. It is built for those three lines specifically, so it is not a universal tie for other breaker families.
2) Can I use a THT104 handle tie on a two-pole breaker?
No. The THT104 is for one-pole devices only. Multi-pole breakers already have an internal common trip, so there is nothing for the tie to do and it is not intended for that use. Use it where you are ganging separate single-pole TQB, TQC, or TQL breakers for manual on-off together.
3) Instead of a handle tie, should I just install a two-pole breaker?
A multi-pole breaker is the alternative when you need common trip, because multi-pole devices include that internally. The ABB THT104 does not add common trip - it provides coordinated manual on-off switching across adjacent single-pole TQB, TQC, or TQL handles, which is why it is intended for one-pole devices only. If the circuit requires the poles to trip together on a fault, specify a multi-pole breaker; if you only need to switch them together by hand, the THT104 does that without replacing the breakers.
4) Will an Eaton BR handle tie work on ABB TQB or TQL breakers?
No. The Eaton BR handle tie is built for Eaton's BR series single-pole breakers, and handle ties are keyed to the handle geometry of the breaker line they were designed for. For single-pole TQB, TQC, and TQL breakers, the ABB THT104 snap-on handle tie is the part that seats correctly on the handles. Match the tie to the breaker family in the panel rather than to the pole count alone.
5) Do I need any tools or extra hardware to install the ABB THT104?
No extra hardware. It is a solid snap-on tie that presses directly onto the breaker handles, no screws or tools called for. That makes it a quick panel-by-panel change without pulling breakers out.
6) Is a handle tie a cheaper way to avoid replacing single-pole breakers with a two-pole?
That is exactly the case for it. Tying existing single-pole TQB, TQC, or TQL handles together gives you the one-motion manual on-off of a multi-pole unit without swapping breakers. The limit is that you get coordinated switching, not common trip, so it only works where common trip is not a requirement of the installation.
7) I need to gang three single-pole breakers in one panel - is the THT104 the right choice?
It depends on the breaker brand in that panel. The ABB THT104 ties single-pole TQB, TQC, and TQL handles together so they switch as one. If the panel is populated with Eaton BR breakers instead, the Eaton BR handle tie is the one made to span three single-pole BR breakers. Confirm the breaker series stamped on the device before ordering either one.
8) How many handle ties come in a THT104 order?
One each per package. If you are ganging breakers across several panels, order one THT104 per set of handles you intend to tie.
9) Where is the THT104 typically used?
Panelboards and load centers running ABB TQB, TQC, or TQL breakers, in both residential and commercial work. Common cases are multi-circuit control and ganging singles for coordinated switching, on renovations and new construction alike.
