Why Choose the ABB DRTA42 110 V Remote Reset?
The ABB DRTA42 110V, order code DRTA42 110V, is a dedicated electrical remote-reset accessory for compatible ABB thermal overload relays. Designed for use with ABB TA45DU and TA75DU overload relays, it enables an overload relay to be reset remotely rather than requiring manual operation directly at the device.
This DRTA42 version is specified for a 110 V control supply. When installed with a compatible TA45DU or TA75DU thermal overload relay, the remote-reset unit can form part of a motor starter or control system where the overload relay is installed inside an enclosure, switchboard or other location where local manual resetting may be inconvenient.
As a purpose-designed ABB accessory, the DRTA42 110V provides mechanical compatibility with the specified overload relay families and supports remote restoration following an overload trip once the cause of the trip has been identified and the relay is ready to be reset.
Key Advantages
- Dedicated remote-reset accessory for ABB thermal overload relays.
- Specified for a 110 V control supply.
- Designed for compatible ABB TA45DU overload relays.
- Designed for compatible ABB TA75DU overload relays.
- Allows overload-reset operation without direct manual access to the relay.
- Useful for overload relays installed inside control panels and switchgear assemblies.
- Supports convenient motor-starter reset and maintenance arrangements.
- Purpose-designed ABB accessory for reliable mechanical integration with compatible relays.
Key Features
- ABB DRTA42 remote-reset unit.
- 110 V control supply.
- Electrical remote-reset functionality.
- Compatible with TA45DU thermal overload relays.
- Compatible with TA75DU thermal overload relays.
- Designed as an accessory rather than a standalone overload protection device.
- Suitable for industrial motor starters and control-panel applications.
- Enables remote resetting following an overload trip when operating conditions permit.
Convenient Remote Reset for Motor Protection Systems
Thermal overload relays protect motors by responding to sustained overload conditions and interrupting the associated contactor control circuit. After the cause of a trip has been investigated and normal operating conditions have been restored, the overload relay must be reset before the motor starter can return to service. The ABB DRTA42 110V provides a means of performing this reset remotely on compatible TA45DU and TA75DU relays.
Remote reset capability can be particularly useful where motor starters are installed inside enclosed switchboards, machinery control panels or other equipment where direct access to the overload relay is restricted or inconvenient. The DRTA42 should be incorporated into the overall control and safety design so that resetting an overload does not automatically create an unsafe or unintended machine restart.
Typical Applications
- Remote resetting of ABB TA45DU thermal overload relays.
- Remote resetting of ABB TA75DU thermal overload relays.
- Industrial motor starters and motor control centres.
- Machinery and production-equipment control panels.
- Pump, fan, compressor and conveyor motor control systems.
- Switchgear and automation panels where overload relays are not readily accessible.
