ABB UA26 Series Contactor, 24V Control Circuit Voltage, 2A Contact Current - 1SBL241024R8110

This contractor is a Compact 3-pole control unit designed for capacitor switching in industrial power installations. It operates from a 24V AC control circuit and is intended for DIN-rail mounting within electrical panels. The device is suited to installations where inrush currents can far exceed steady-state values and includes built-in measures to manage switching transients.

Features & Benefits

• 3P configuration limits switching to three-phase capacitor banks
• Rated operational current 2A enabling small-capacitor control
• Integrated damping resistors reduce energisation current peaks
• Coil consumption with defined pull-in and holding values aids control design
• Screw terminals accept 0.75 to 4mm² cables for robust wiring
• Operational range down to -40°C supports cold-environment use

Applications

• Suitable for capacitor bank switching in power-factor correction panels
• Ideal for serial insertion of damping resistors during energisation
• used with low-power reactive components up to 690V system voltage
• Can be used for automated switching in industrial motor control rooms

What protection is recommended for the switching circuit?

Use gG-type fuses coordinated with the auxiliary circuit ratings

standard recommendations include 10A protection for auxiliary circuits and appropriate short-circuit protective devices sized to system fault currents.

How does the control Coil behave electrically?

The Coil provides specified pull-in and holding VA values at 50/60Hz, with measured operate times between 8 to 21ms for closing and 4 to 11ms for opening, useful for timing sequences.

What insulation and impulse withstand ratings apply?

Insulation is rated to 1000V (IEC/VDE) with an impulse withstand voltage of 8kV, allowing application in systems with elevated transient levels.

How is the unit mounted and connected mechanically?

The unit clips to DIN rail and uses Pozidriv M4 screws with cable clamps on the screw terminals for secure electrical connections.
