Why Choose the ABB 1SAX101911R1003 DRS-F-03 Remote Reset Coil?
The ABB 1SAX101911R1003 (DRS-F-03) is a compact and reliable remote reset coil for ABB overload relays, designed to allow compatible thermal and electronic overload relays to be reset electrically from a remote control location. It provides a practical solution for industrial motor protection systems where direct access to the overload relay is inconvenient or where reset functionality needs to be incorporated into a centralised control system.
The DRS-F-03 is suitable for ABB TF42, TF65 and TF96 thermal overload relays and compatible ABB EF electronic overload relays. To enable remote resetting, the overload relay is configured for manual reset operation. A short electrical pulse then actuates the reset mechanism, allowing the protection device to be returned to its operating state without an operator physically pressing its reset control.
Designed for a 110–127 V control supply, the DRS-F-03 is intended for pulsed rather than continuous operation. The specified reset pulse duration is 0.2–0.35 s. Its compact dimensions of approximately 43 × 44 × 60 mm make it straightforward to integrate with compatible ABB overload protection equipment in motor starters and industrial control panels.

Reliable Remote Reset for Motor Protection Systems
Remote reset coils allow an overload protection device to be reset electrically without requiring an operator to access the relay directly. This is particularly useful in automated machinery, motor control centres and remotely located electrical panels where centralised control can reduce manual intervention and simplify recovery following an overload trip.
The ABB DRS-F-03 works with compatible ABB overload relays configured for manual reset. Once the overload condition has cleared and the motor protection system is ready to be restored, a short 0.2–0.35 s electrical pulse to the DRS-F-03 actuates the relay's reset mechanism. The coil is specifically intended for this momentary operation and should not be continuously energised.
Typical Applications
- Industrial motor starter assemblies.
- Motor control centres and electrical control panels.
- Automated production and manufacturing machinery.
- Conveyor and material handling systems.
- Pumps, fans and process equipment.
- Remote and centrally controlled motor protection systems.
