Eaton SLX010A1-4A1B0 – 4-Pole Contactor, 10A

The Eaton SLX010A1-4A1B0 is a compact, high-performance contactor from the SLX series, designed for switching electrical loads in industrial and commercial applications. With four poles and a rated operational current of 10 A in AC-3 utilization category, it is ideal for controlling three-phase motors, resistive loads, lighting circuits, and other equipment.

Design and Construction

The contactor features a robust construction with silver alloy contacts for high electrical endurance and low contact resistance. The arc chutes are designed to quench arcs quickly, extending contact life. The coil is encapsulated for protection against dust and humidity, and operates on standard control voltages (typically 24 V DC, 110 V AC, or 230 V AC – check coil code).

Key Features

• 4 Poles: Four normally open (NO) main contacts for versatile switching configurations.

• Rated Current: 10 A at 400 V AC (AC-3) for motor control; higher ratings for AC-1 (resistive) loads.

• Compact Size: Space-saving design allows high-density mounting in control panels.

• Auxiliary Contacts: The 4A1B0 suffix indicates the presence of auxiliary contacts (typically 4 NO + 1 NC) for status feedback or interlocking.

• DIN Rail Mounting: Standard 35 mm DIN rail mounting for easy installation.

• Markings: Clear terminal markings and UL/CSA certifications.
