ABB UA16 Series Contactor, 16A Operational Current, 230 to 240V Control Circuit Voltage - 1SBL181022R8810


This contractor is a compact, three-pole control unit designed for switching capacitor banks in industrial control installations. It operates from a 230/240V AC control circuit and is configured with three main normally open poles and one built-in auxiliary contact, providing focused functionality for capacitor switching where inrush peaks comply with the device’s limits.

Features & Benefits


• Rated operational current 16A enabling moderate load switching
• Supports capacitor switching with Peak inrush allowance up to 100x nominal
• Coil rated 230 to 240V for compatibility with common control supplies
• Screw terminals simplify secure connections and cable clamp fixing
• DIN rail mounting for efficient panel installation and space saving
• Electrical durability of 100000 operating cycles under specified conditions

Applications


• Suitable for switching capacitor banks in reactive power compensation panels
• Used for control of motor-starting reactive circuits with limited inrush
• Ideal for integration into automation panels requiring DIN rail components
• Suitable for installers needing a Compact 3-pole contactor for retrofit

What ambient temperatures can it tolerate during operation?


It can operate in free Air between -40°C and +55°C when supplied at 0.85 to 1.1Uc and up to +70°C at rated Uc under specified conditions.

How is the unit protected against electrical transients?


The device has a rated insulation voltage of 1000V and an impulse withstand capability of 8kV to withstand transient stress.

What are the connection capacities for main and auxiliary circuits?


Main and auxiliary circuits accept flexible cable with ferrules from 0.75 to 2.5mm² and rigid conductors from 1 to 4mm².

How fast does it respond electrically when energised or de-energised?


Typical operate times are 10 to 26ms for Coil energisation to contact closing and 4 to 11ms for release to NO contact opening.

Which protective device ratings are recommended for short-circuit protection?


Use gG type fuses 1.5 to 1.8A for certain circuits and 10A for the auxiliary protection as indicated by the device’s protection guidance.
