Where it sits in the board
Motor starters next to MCCB feeders, and load-break isolators on PV strings or HVAC boards that already use NEELE SPD and MCB.
How to write the RFQ
Write utilisation category, coil voltage, poles and whether the isolator is lockable. Example: 3P 32 A AC-3, 230 V coil, 500 pcs.

Contactors & Isolators
AC contactors and rotary isolators for motor and PV circuits, tooled on the same Liushi campus as the breaker families.
Are contactors private-label?
Laser marking and coil-voltage variants are quoted from 500 pcs. A unique housing colour follows the 1,000-piece MCB rule because it needs a mould change.
Which files sit behind the family?
Contactors: IEC 60947-4-1 (AC-3). Rotary isolators: IEC 60947-3. Reports attach to the quotation the same way as MCB files.
What is the MOQ for OEM / private label?
Private-label programmes start at 1,000 pieces per rating. In-house tooling keeps most MCB and SPD families inside eight weeks.
