Why Choose the ABB GAE75-10-11 Contactor?
The ABB GAE75-10-11 is a specialised DC-operated, single-pole contactor designed for reliable switching of direct-current power circuits. Part of the ABB GAE75 range, it uses three main poles connected in series to provide the multiple contact breaks required for effective DC interruption.
The GAE75 design incorporates permanent-magnet arc chutes specifically engineered for DC breaking. Its series-connected main poles make it suitable for controlling DC motors as well as resistive and slightly inductive DC loads, while the fitted 1NO + 1NC auxiliary contacts provide useful signalling, feedback and interlocking functions.
ABB order code 1SBL419025R8011 identifies this exact GAE75-10-11 configuration with a 12 V DC control circuit. It provides an IEC DC-1 rated operational current of 100 A at 440 V DC and up to 55 °C, together with a UL/CSA general-use rating of 100 A at 440 V DC.
Key Advantages
- Purpose-designed ABB GAE75 contactor for DC power switching.
- 12 V DC operating coil for low-voltage DC control systems.
- 100 A DC-1 operational current at 440 V DC.
- Three main poles connected in series for effective DC current interruption.
- Permanent-magnet arc chutes specifically designed for DC breaking.
- Fitted 1NO + 1NC auxiliary contacts for signalling and control functions.
Key Features
- ABB GAE75 contactor series.
- DC-operated single-pole contactor configuration.
- Three main poles connected in series.
- 1NO + 1NC fitted auxiliary contacts.
- 12 V DC rated control circuit voltage.
- 100 A IEC DC-1 rating at 440 V DC.
- 100 A UL/CSA general-use rating at 440 V DC.
- Permanent-magnet arc chutes for DC interruption.
Specialised Switching for Industrial DC Circuits
Direct-current interruption requires dedicated contactor construction because DC does not provide the regular current zero-crossings available in AC circuits. The ABB GAE75-10-11 addresses this requirement by connecting three main poles in series and using permanent-magnet arc chutes specifically designed to assist DC arc interruption.
With a 12 V DC control circuit and a 100 A DC-1 rating at 440 V DC, this configuration is suited to industrial DC installations requiring low-voltage contactor control. The fitted 1NO + 1NC auxiliary contacts can also be incorporated into control, interlocking and status-feedback circuits.
Typical Applications
- Industrial DC power circuit switching.
- Resistive and slightly inductive DC loads.
- DC motor control applications.
- Battery-powered industrial equipment.
- DC distribution and control panels.
- Machinery using a 12 V DC contactor control supply.
