Description
Typical Technical Specifications (for UKM5 series)
Here are typical specs you should check for the specific model (values may vary by variant):
-
Rated operational voltage (Ue): up to AC 690 V.
-
Rated insulation voltage (Ui): AC 750 V. zjkripal.en.made-in-china.com
-
Rated impulse withstand voltage (Uimp): e.g., 8 kV. zjkripal.en.made-in-china.com
-
Breaking capacity: high breaking capacity versions available (for example one spec for 3-pole 200 A AC version shows breaking capacity of 105 kA).
-
Poles: 3P (three-phase) or 4P (three-phase plus neutral) configurations possible.
-
Frame size and adjustability: The “frame” (UKM5) supports a certain current range; within the frame there are models/sub-frames (e.g., “UKM5-100”, “UKM5-400S”, “UKM5-630”). For instance “UKM5-100” model is cited. kripal.com+1
What to Ask/Check When Specifying
-
Confirm the exact In (rated current) you require (e.g., 30 A, 63 A, 125 A, 250 A, 400 A, 630 A).
-
Confirm the exact model/variant code (frame size, short-circuit capacity, pole count).
-
Confirm Ue (rated operational voltage) fits your system (e.g., 400 V, 690 V).
-
Confirm breaking capacity (Icu and Ics) suits your fault level in PSU or distribution board.
-
Confirm trip characteristics (thermal + magnetic), adjustable settings if required (for motor feeders, etc).
-
Check accessories: shunt trip, auxiliary contacts, undervoltage trip, remote signalling.
-
Check mounting/connection: whether busbar or cable connection, torque values, clearances.
-
Check local standards/regulations in Pakistan (IEC vs local code) for certification.
-
Confirm derating factors (ambient temperature, altitude, grouping of breakers) for correct sizing.
