ABB UA16 Series Contactor, 80A Contact Current, 230/240V Coil Voltage - 1SBL181024R8810


This contactor is a compact, three-pole switching device designed for capacitor bank control in industrial installations. It operates with an AC control circuit and integrates front-mounted damping resistors to limit inrush and pre-charge capacitors, making it suitable where Peak currents greatly exceed nominal values. The unit is intended for DIN-rail mounting and includes a single normally open auxiliary contact for control and signalling functions.

Features & Benefits


• 80A operational current supports heavy-duty switching loads
• 690V rated voltage allows use up to high-voltage systems
• 230 to 240V Coil consumption specified for AC control circuits
• 3NO main pole arrangement ensures independent three-phase switching
• Screw terminals provide secure DIN-rail connection
• Damping resistors limit capacitor energisation current peaks

Applications


• Suitable for capacitor switching panels in power factor correction
• Ideal for installation in industrial automation control cubicles
• Can be used for sequential capacitor bank pre-charging arrangements
• Suitable for retrofit or new DIN-rail distribution board assemblies

What are the electrical endurance expectations for heavy switching?


The device is rated for up to 250,000 operating cycles when switching below 500V and 100,000 cycles for voltages between 500V and 690 V, reflecting its durability under frequent capacitor operations.

How does the front-mounted Block affect operation?


The front Block places three damping resistors in series with each phase to reduce initial inrush and provide controlled pre-charging, reducing the secondary current Peak at main pole closure.

What environmental temperature ranges are supported during operation?


It is specified for operation in free Air from −40 °C up to +70 °C when run at rated control voltage, with storage capability down to −60 °C.

Which short-circuit protective devices are applicable?


The product is compatible with gG fuses up to 80A for short-circuit protection and has maximum breaking capacity values defined for 440V and 690V systems.

What connection sizes are acceptable for field wiring?


Main and auxiliary circuits accept flexible conductors with ferrules from 0.75mm² to 2.5mm² and rigid conductors from 1mm² to 4mm² using the screw-type terminals.
