The ABB UA26-30-10RA-86, product ID 1SBL241024R8610, is a 3-pole capacitor switching contactor with pre-insertion resistors designed for controlling capacitor banks in industrial power factor correction systems. As part of the ABB UA..RA contactor range, it is specifically designed for applications where capacitor energisation can produce peak currents far exceeding 100 times the nominal RMS current.
The UA26-30-10RA-86 features three normally open main contacts and one normally open built-in auxiliary contact. Under AC-6b duty, it is rated for capacitor banks up to 22 kvar at 400 V. The integrated pre-insertion resistors help limit the high inrush current generated when capacitors are energised, reducing switching stress on the contactor and associated electrical equipment.
Its AC-operated laminated magnet circuit uses a 400–415 V AC coil at 50 Hz or 415–440 V AC at 60 Hz. Screw-terminal connections provide secure wiring, while the compact 120 × 54 × 126.3 mm construction makes the UA26-30-10RA-86 suitable for integration into automatic power factor correction panels and industrial capacitor switching assemblies.
Energising capacitor banks can generate extremely high transient currents that place considerable electrical and mechanical stress on switching equipment. The ABB UA26-30-10RA-86 incorporates pre-insertion resistors that help limit the initial current peak during capacitor energisation before the main contacts complete the switching operation.
This dedicated design allows the UA26-30-10RA-86 to be used in installations where peak current can far exceed 100 times the nominal RMS current. Its 22 kvar rating at 400 V and high-voltage AC control coil make it well suited to automatic power factor correction and reactive power compensation systems.
