The ABB 1SFL597025R7111, designated GAF460-10-11-71, is a robust three-pole DC contactor designed for DC-1 switching applications at operational voltages up to 1000 V DC. Its three main poles are connected in series to provide a single-pole switching configuration for demanding high-power direct-current circuits.
Part of the ABB GAF contactor range, this device combines high-current DC switching capability with an electronically controlled wide-range coil. The 250–500 V AC/DC control circuit supports operation from either 50/60 Hz AC or DC control supplies while helping accommodate control-voltage variations.
The GAF460-10-11-71 provides a DC-1 rated operational current of 700 A at 1000 V DC and 40 °C. It also incorporates one normally open and one normally closed auxiliary contact for signalling, electrical interlocking and integration with industrial control systems.
DC contactors provide controlled connection and disconnection of direct-current loads. In the ABB GAF460-10-11-71, all three main poles are connected in series to interrupt a single DC circuit at operational voltages up to 1000 V DC.
The electronically controlled coil supports operation across a wide 250–500 V AC/DC control range. Integrated auxiliary contacts allow the contactor’s switching state to be incorporated into signalling, interlocking and automated control circuits.

This contactor is designed for switching DC-1 loads in high-power direct-current systems at operational voltages up to 1000 V DC.
With its three main poles connected in series, the contactor has a DC-1 rated operational current of 700 A at 1000 V DC and 40 °C.
The electronic coil operates from a 250–500 V AC supply at 50/60 Hz or a 250–500 V DC supply.
All three main poles must be connected in series to create a single normally open switching path for operation at up to 1000 V DC.
The GAF460-10-11-71 includes one normally open and one normally closed auxiliary contact for control, signalling and interlocking functions.
ABB GAF contactors provide dependable control of demanding DC loads, combining high-voltage switching capability, wide-range electronic coil control and integrated auxiliary contacts for modern industrial power systems.
