1. Verify Interrupting Capacity. 2. Verify circuit breaker amperage. 3. Verify trip unit (thermal magnetic,electronic trip, magnetic only, etc.). 4. Verify number of poles. 5. Verify accessories.
Tmax breakers are available with thermal magnetic trip units from 15A to 800A. The minimum operating voltage is 24VDC.
1. A circuit breaker with a straight voltage marking e.g. 480V or 600V, maybe applied in a circuit where the nominal voltage between any two conductors does not exceed the circuit breakers ratings. 2. A circuit breaker with a slash rating e.g. 480Y/277V or 600Y/347V, may be applied in a circuit where the nominal voltage to ground from any conductor does not exceed the lower of the two values of the circuit breaker voltage rating, and the nominal voltage between any two conductors does not exceed the higher value of the circuit breaker's voltage rating.
Hoffman enclosures with a universal cut out requires an adapter plate provided by Hoffman. As with all enclosure manufactures the customer should consult the enclosure manufacturer's catalog.
We do not sell a kirk key....we only sell the provisions for the kirk key on the E-Max breakers We do Sell a Kirk Key lock adaptor plate if you want to look at the instruction sheet go here: http://www.abb.us/product/seitp329/9cf15f0e967bde44c1256fea002370be.aspx and click on kirk key lock for open position oustide door.

Yes when you use the PR122/P-LSIG or the PR123/P-LSIG it is possible to disable the trip control of the G protection function. Circuit breaker opening does not take place, only the alarm condition is signaled. For remote signaling of the alarm the electrical signaling module can be used.
An ammeter is standard on both the PR122/P and the PR123/P trip units.
