Why Choose the ABB DRTA42 24 V Remote Reset?
The ABB DRTA42 24V, order code DRTA42 24V, is a dedicated electrical remote-reset accessory for compatible ABB thermal overload relays. Designed specifically for ABB TA45DU and TA75DU overload relays, it enables the overload relay to be reset remotely instead of requiring direct manual operation at the device.
This DRTA42 version is specified for a 24 V control supply, making it suitable for industrial motor-control systems that use low-voltage control circuits. When fitted to a compatible TA45DU or TA75DU thermal overload relay, it provides convenient electrical reset functionality for installations where the overload relay is located inside an enclosure, switchboard or machinery control panel.
As a purpose-designed ABB accessory, the DRTA42 24V provides the mechanical and functional interface required for remote reset of the specified overload relay families. It is particularly useful in motor starters and automated equipment where operators or control systems need a remote means of resetting an overload relay after the trip condition has been investigated and cleared.
Key Advantages
- Dedicated remote-reset accessory for ABB thermal overload relays.
- Specified for a 24 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.
- Well suited to modern low-voltage industrial control circuits.
- Useful for overload relays installed inside control panels, switchgear and machinery.
- Purpose-designed ABB accessory for motor protection and starter-control applications.
Key Features
- ABB DRTA42 remote-reset unit.
- 24 V control supply.
- Electrical remote-reset functionality.
- Compatible with TA45DU thermal overload relays.
- Compatible with TA75DU thermal overload relays.
- Designed as an overload relay accessory rather than a standalone protection device.
- Suitable for industrial motor starters and control panels.
- Enables remote resetting following an overload trip once operating conditions permit.
Convenient 24 V Remote Reset for Motor Protection Systems
Thermal overload relays protect motors against sustained overload conditions by causing the associated contactor control circuit to open when an overload is detected. Once the cause of the trip has been identified and corrected, the overload relay must be reset before normal motor-starter operation can resume. The ABB DRTA42 24V provides an electrical means of performing this reset remotely on compatible TA45DU and TA75DU relays.
Remote reset functionality is particularly useful where motor starters are located inside enclosed switchboards, machinery control cabinets or other locations where direct access to the overload relay is inconvenient. The DRTA42 should be incorporated into the overall machine and control-system design so that resetting an overload condition does not result in an unintended or unsafe 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 using 24 V control circuits.
