Description
Inside a crowded control panel, a full-size wrench has nowhere to swing. Panel builders still need a set torque on breaker, relay and terminal screws, though. The Snap-on QD2R200A torque wrench addresses that problem. It is a compact 3/8″ drive click wrench with a fixed ratchet head, and it sets from 40 to 200 in-lb.
Why loose terminals matter
A loose terminal heats up under load, and that heat can damage insulation over time. On the other hand, too much torque can crack a breaker housing or crush a conductor. So electrical makers publish torque values for their terminals, and inspectors expect panel shops to follow them. A click wrench such as the QD2R200A turns those values into a repeatable routine.

- Breaker and contactor terminal screws, when the value falls in range.
- Ground bar, neutral bar and PE terminal hardware.
- Busbar support and DIN rail bracket screws.
- Gland plate and mounting plate fasteners.

Compact body plus ratchet: the practical gain
A compact wrench helps where cable ducts and DIN rails crowd the space. Meanwhile, the ratchet head lets the builder turn a screw in short arcs. As a result, one Snap-on QD2R200A torque wrench can handle both the run-down and the final click on many terminals. That saves real time on a panel with dozens of connections.
Converting terminal specs
European and Asian breaker makers often list torque in N·m, while US makers tend to use in-lb. For N·m, divide by 0.113 before you set the QD2R200A. For example, 8 N·m comes to about 71 in-lb, and 14 N·m comes to about 124 in-lb. Small terminals often sit below 40 in-lb, and a torque screwdriver handles those better.
Care inside a panel shop
Copper filings and cable offcuts get everywhere in a panel shop. Therefore, keep the QD2R200A in its case between jobs and blow the head clean if debris builds up. Wind the scale down to 40 in-lb at the end of the day. Also log the serial number on the panel test sheet, so the customer can trace each torque check.

Panel builder FAQ
How does the Snap-on QD2R200A torque wrench differ from the GQT2R200NP?
Both are 3/8″ drive ratchet models that set from 40 to 200 in-lb. The QD2R200A listing describes it as a compact model, so ask Lost in HCM to compare the two for your panels.
Can I use the QD2R200A on busbar bolts?
Only if the maker’s value sits at or under 200 in-lb. Larger busbar joints often need more, so check the spec before you pick the QD2R200A.
Who handles a QD2R200A order?
Lost in HCM supplies the QD2R200A and sends the quote. SMK Vietnam only lists it.
