ABB UA26 Series Contactor, 16A Operational Current, 48V Control Circuit Voltage Uc - 1SBL241022R8310


This contactor is a three-pole switching device designed for control of capacitor banks and general control circuits in industrial electrical installations. It operates from an AC control Coil and is intended for DIN‑rail mounting in panels where a Compact footprint and robust switching of reactive loads are required. The unit includes an integrated auxiliary contact for control signalling and is specified for use across a wide ambient temperature range.

Features & Benefits


• 16A operational current for switching moderate load currents
• 48 VAC Coil compatible with 50/60 Hz control supplies
• 3NO main poles with 1NO auxiliary contact for simplified control wiring
• Rated to 690V for high‑voltage capacitor circuits
• Screw terminals provide secure conductor connections
• Wide operating temperature range from −40 to 70 °C for harsh sites

Applications


• Suitable for capacitor bank switching in power factor correction installations
• Can be used for control circuits in automation cabinets
• Ideal for retrofit DIN‑rail panels requiring Compact contactors
• Used with capacitor units where high Peak inrush currents are limited

What inrush conditions can it handle when switching capacitors?


It accepts capacitor bank inrush peaks up to 100 times the nominal rms current when capacitors are discharged to ≤50V before reclosing.

How Durable is the mechanism under cyclic operation?


Mechanical endurance is specified at 10 million operations and electrical life reaches 100,000 switching cycles under the stated capacitor switching conditions.

What mounting and Terminal arrangements are provided?


It is designed for DIN‑rail installation and uses screw‑type terminals with cable clamps for secure connections.

Which protection ratings and voltages apply to the main and auxiliary circuits?


Both main and auxiliary circuits are rated to 690V with an insulation voltage of 1,000V and an impulse withstand of 8 kV.
