ABB UA75 Series Contactor, 220/230VAc Control Circuit Voltage, 690V Contact Voltage - 1SBL411022R8000


This contractor is a three-pole switching device designed for capacitor bank control in industrial electrical systems. It operates from an AC control supply and is intended for DIN-rail mounting in panels where controlled engagement of capacitors is required, particularly where inrush peaks do not exceed specified multiples of nominal current. The unit is suited to environments with a wide ambient temperature range and accepts screw-terminal connections for main circuit wiring.

Features & Benefits


• 3NO main poles enable direct three-phase capacitor switching
• 220 to 230VAc Coil reduces control-voltage inventory
• Rated for up to 690V main circuit for high-voltage applications
• Accepts Peak inrush up to 100x nominal current for capacitor banks
• Mechanical endurance of 10,000,000 operations supports long service life
• Operating ambient range −40 to 70°C suits varied site climates

Applications


• Suitable for staged switching of power-factor correction capacitors
• Used for controlling capacitor banks in industrial distribution panels
• Ideal for retrofit DIN-rail installations in motor control centres
• can be used with systems requiring screw-terminal power connections

What type of terminals are provided for the main conductors?


The main poles use screw-type terminals able to accept flexible cables with ferrules and solid conductors within specified cross-sections.

How quickly does it respond when energised or de-energised?


Typical operate times are 8 to 27 MS for Coil pull-in and 4 to 11 MS for release, enabling Rapid switching cycles.

What electrical durability can be expected when used with discharged capacitors?


When capacitors are discharged to ≤50V before making, electrical life is specified at 100,000 operating cycles.

What protection and insulation ratings apply to the unit?


The device meets a rated insulation voltage up to 1,000V and a rated impulse withstand of 8 kV, with Coil Terminal enclosure at IP20.

Which control frequencies are supported for the coil?


The Coil supports 50 Hz operation at 220 to 230V and 60 Hz operation at 230 to 240 V.
