ABB UA26 Series Contactor, 16A Contact Current, 24VAc Coil Voltage - 1SBL241022R8110

This contactor is a three‑pole control unit designed for switching capacitor banks in industrial electrical systems. It operates from an AC control circuit and is intended for DIN‑rail installation in control panels. The device is suitable where controlled engagement of capacitors is required while managing inrush peaks and frequent switching cycles.

Features & Benefits

• 3P switching limits contacts to three main poles for capacitor control
• 16A conventional thermal current supports moderate load switching
• 24V AC control circuit enables common low‑voltage panel integration
• Accepts Peak inrush up to 100x nominal rms current protecting banks
• 3600 cycles per hour mechanical frequency for high switching rates

Applications

• Suitable for staged capacitor bank switching in power factor correction
• Ideal for motor control centres requiring reactive power management
• used with low‑voltage distribution panels for load compensation
• Can be used for retrofit replacement in existing contactor arrays

What Terminal types are provided for connection?

Screw terminals are supplied for both main and auxiliary circuits, with Pozidriv screws and cable clamps for secure terminations.

How does the product perform at elevated ambient temperatures?

It maintains rated operational powers with reduced kvar capacities as temperature rises, with specific permitted kvar values defined up to 70°C near the device.

What protection and fuse recommendations apply?

Auxiliary circuits are compatible with gG fuses and recommended short‑circuit protective devices range to match operational currents specified for different voltages.

What mechanical and electrical durability can be expected?

When capacitors are discharged to ≤50V before re‑energisation, electrical endurance reaches 100000 operating cycles with a block‑type pole design.
