ABB UA75 Series Contactor, 380/400V Control Circuit Voltage, 1300A Operational Current Ie - 1SBL411022R8500

This contactor is a three-pole device designed for switching capacitor banks in industrial electrical installations. It operates from an AC control supply around 380 to 400V (50 Hz) or 400 to 415V (60 Hz) and is intended for high‑current capacitor switching where inrush peaks do not exceed 100 times the nominal RMS current. The unit is built for DIN‑rail mounting and is delivered with screw‑type main terminals.

Features & Benefits

• Rated operational current 1300A delivers high‑current switching capability
• Three normally open poles provide dedicated capacitor‑switching contacts
• 690V main‑circuit rating supports medium‑voltage capacitor banks
• Coil consumption and pull‑in values enable predictable control performance
• Mechanical durability of 10 million operations ensures long service life
• Operating temperature range from -40 °C to +70 °C suits varied site conditions

Applications

• Suitable for switching low‑inductance capacitor banks in power‑factor correction
• Ideal for industrial motor control rooms requiring intermittent capacitor switching
• Can be used for retrofit capacitor bank panels on DIN‑rail backplates
• Used for centralised capacitor control in commercial electrical distribution

What connection types are provided for the main circuit?

Main poles use screw terminals capable of flexible cable with crimped end ferrules or rigid conductors sized for heavy currents.

How fast does the contactor operate electrically?

Typical timings range from 8 to 27 MS for contact closing after Coil energisation and 4 to 11 MS for contact opening after Coil release.

What environmental limits apply for storage and operation?

It can be stored between -60 °C and +80 °C

permitted operating ambient temperature ranges vary with control voltage, allowing up to +70 °C for the rated control supply.

What protections or standards relate to insulation and impulse resistance?

The device is rated for 690V operational insulation, with an impulse withstand of 8 kV and tested up to 1 000V for certain standards.
