ABB UA63 Series Contactor, 115A Contact Current, 400 to 415V Control Circuit Voltage Uc - 1SBL371022R8500

This contactor is a three-pole control unit designed for switching capacitor banks in industrial electrical systems. It operates from standard industrial control voltages and is intended for installations where frequent capacitor switching and high Peak currents occur. The device is built for DIN-rail mounting and is supplied with screw-type connections for main conductors.

Features & Benefits

• 115A rated operational current provides high continuous load handling
• Accepts inrush peaks up to 100 times nominal current for capacitor switching
• Coil designed for 400 to 415V control voltage ensuring compatibility with AC control systems
• Electrical durability up to 100,000 operating cycles for extended service life
• Operates reliably from -40°C to +70°C for wide ambient conditions
• Maximum breaking capacity 1,300A at 440V supports heavy fault interruption

Applications

• Suitable for power factor correction in industrial motor installations
• Ideal for switching capacitor banks in distribution panels
• Can be used for centralised reactive power management in factories
• Suitable for replacing worn contactors in automated capacitor banks

What is the expected mechanical endurance under regular operation?

Mechanical life is specified at 10 million cycles with a maximum mechanical switching frequency of 3,600 cycles per hour.

How should capacitors be managed to ensure correct switching behaviour?

Capacitors must be discharged so residual voltage at terminals is ≤50V before re-energisation to meet rated electrical durability.

Which voltages and power ratings are supported for AC-3 switching?

AC-3 power capability includes up to 45kvar at 400/415V 40°C and up to 70kvar at 690V 40°C with reduced values at higher ambient temperatures.

What are the Terminal connection options and conductor sizes?

Main circuit screw terminals accept flexible conductors with ferrules and rigid conductors

main circuit capacity supports flexible 6 to 16mm² and rigid 6 to 25mm².

What insulation and impulse withstand performance does it offer?

Rated insulation voltage is 1,000V for IEC use and rated impulse withstand voltage is 8kV.
