Why Choose the ABB GAE75-10-00 125V DC Contactor?
The ABB GAE75-10-00, order code 1SBL419025R8700, is a DC-operated contactor for DC load switching, designed for applications including shunt and series motors as well as resistive and slightly inductive loads. The GAE75 range uses a specialised contact system engineered for reliable interruption of DC circuits.
Although classified as a one-pole contactor, the GAE75 uses three internal main poles connected in series to achieve its DC switching performance. The main-pole arc chutes incorporate permanent magnets specifically designed for DC breaking, so the specified connection polarity must be observed during installation.
This exact 1SBL419025R8700 version has a 125 V DC control coil and no factory-fitted auxiliary contacts. It provides a rated operational current of 100 A DC-1 at 440 V DC at temperatures up to 55 °C, making it suitable for demanding industrial DC switching and motor-control systems.
Key Advantages
- Purpose-designed for industrial DC circuit switching.
- 125 V DC control coil.
- 100 A DC-1 rating at 440 V DC up to 55 °C.
- Three internal main poles connected in series for effective DC interruption.
- Permanent-magnet arc chutes specifically engineered for DC breaking.
- Suitable for shunt motors, series motors and resistive or slightly inductive DC loads.
- Block-type construction with compatibility for add-on auxiliary contact accessories.
Key Features
- ABB GAE75-10-00 DC contactor.
- 1-pole DC switching configuration.
- 3 internal main poles connected in series.
- 125 V DC rated control circuit voltage.
- No factory-fitted auxiliary contacts.
- 100 A DC-1 at 440 V DC.
- DC main-circuit capability up to 1000 V DC, subject to applicable operational-current ratings.
- Permanent-magnet arc chutes for DC interruption.
- Screw terminals.
- Side-mounted auxiliary contact blocks can be added where required.
Reliable High-Voltage DC Load Switching
Switching DC loads presents different interruption requirements from conventional AC circuits because there is no natural current zero-crossing to assist arc extinction. The ABB GAE75 design addresses this by using three main poles connected in series and arc chutes fitted with permanent magnets specifically designed for DC breaking.
The GAE75-10-00 is suitable for controlling shunt or series DC motors and resistive or slightly inductive loads. Its 100 A DC-1 rating at 440 V DC, 125 V DC coil and capability for higher-voltage DC circuits at the applicable ratings make it a practical choice for industrial DC control installations. Because permanent magnets are used for arc control, the specified main-circuit connection polarity must be respected.
Typical Applications
- Industrial DC power-circuit switching.
- Shunt-wound DC motor control.
- Series-wound DC motor control.
- Resistive DC loads.
- Slightly inductive DC loads.
- Industrial machinery and DC control panels.
