Why Choose the ABB OTM63F4C20D400C Automatic Transfer Switch?
The ABB OTM63F4C20D400C is a compact 63 A four-pole motor-operated automatic transfer switch designed for reliable transfer between two electrical power sources. Part of the ABB OT Compact ATS range, it integrates the changeover switch, motor operator and transfer control into a self-supplied assembly for electrical distribution applications.
The OTM63F4C20D400C is a C20D fixed-control version intended for network/network applications. It provides open-transition 1-0-2 operation with predefined operating delays and voltage thresholds, allowing automatic transfer between two supplies without requiring adjustable transfer parameters at commissioning.
Rated at 63 A with a four-pole configuration, the OTM63F4C20D400C operates on 380–415 V AC systems and provides an AC-23A operational power rating of 30 kW. Top-in voltage sensing, simultaneous switching of the fourth pole and integrated motor operation make it a practical solution for compact automatic source-transfer installations.

Automatic Network-to-Network Power Transfer
The ABB OTM63F4C20D400C combines motor-operated power switching and automatic source-transfer control within one compact assembly. Its open-transition 1-0-2 switching sequence provides a disconnected position between the two sources, ensuring the active supply is disconnected before the alternative supply is connected.
The C20D controller is specifically designed for network/network applications and uses predefined delay times and voltage thresholds. This fixed-parameter approach provides straightforward automatic transfer operation for installations that do not require configurable transfer settings, while the direct-mounted handle retains manual operating capability when required.
Typical Applications
- Network-to-network automatic power source transfer.
- Commercial building electrical distribution.
- Industrial electrical distribution panels.
- Critical load supply selection between two network sources.
- Four-pole automatic source-transfer systems.
- Compact switchboards requiring integrated motorised transfer control.
