ABB GJL121 Series Contactor, 20A Contact Current, 110 to 125V Control Circuit Voltage - GJL1213501R0004

This contactor is a Compact switching device designed for control circuits in commercial, industrial and residential installations. It operates with a control circuit voltage in the 110–125V range and switches alternating loads up to 20 A at voltages as high as 690 V, providing a Compact solution for motor and load control where space is limited.

Features and Benefits:

• Four poles allowing switching of multi‑phase loads and improved isolation
• Screw terminals for secure, high‑integrity electrical connections
• Rated operational current 20 A enabling moderate power switching
• Power handling of 2.2 kW suitable for small motor drives and equipment
• Conforms to IEC and UL contactor standards for consistent performance
• DIN rail or wall mounting gives flexible installation options

Applications

• Suitable for control panels in light industrial automation systems
• Ideal for switching small three‑phase motors in workshops
• Used with HVAC equipment in commercial buildings
• Can be used for residential distribution and load control setups

What mounting methods are available for installation?

It supports both DIN‑rail and direct wall mounting to suit panel and enclosure arrangements.

How many poles does it provide and why does that matter?

It is a four‑pole device, which permits simultaneous switching of all conductors in multi‑phase circuits for coordinated control.

Which Terminal style is used and what is the benefit?

Screw‑type terminals are provided to ensure a robust mechanical and electrical connection for conductors.

What operating temperature range should be observed?

The device is designed to function between −20 °C and 55 °C, accommodating typical indoor industrial environments.
