Plug-in and withdrawable ordering
T4 / T5: fixed, plug-in or withdrawable; T6 / T7 / T7 M: fixed or withdrawable. Conversion selection is limited to listed three- and four-pole kits; T5 600A conversion kits are offered only in verified 3P UL combinations.
The complete assembly consists of the exact fixed front-terminal base breaker, its pole- and frame-rating-matched conversion kit, and a matching fixed part (cradle). The base ABB product ID stays identified separately; the selector lists each installation and electrical-accessory ordering code. No single assembled product ID is invented. Specify factory fitting of the selected assembly and accessories.
| Fixed-part terminals | EF: front extended; HR: rear horizontal; VR: rear vertical. Only catalogue-valid terminal options are offered for the selected frame and mounting. |
|---|---|
| Mandatory installation parts | Conversion kit and cradle are added automatically. A withdrawable front for lever operation is added where required; choosing a compatible rotary handle or motor replaces that front. |
| Auxiliary connections | T4/T5/T6 plug-in and withdrawable assemblies include the matching ADP adapters. For T7/T7 M withdrawable assemblies, required fixed-part sliding contact blocks are separate order items; the matching moving-part blocks are shown as included with factory-fitted electrical accessories or applicable PR331/P / PR332/P trip units, avoiding duplicate orders. |
| Quote list | Stores the complete base model and ABB product ID, frame rating, mounting, fixed-part terminals, selected accessory voltages/contact arrangements and all required installation references. Quantities shown are per base device. |
