ABB OTM1000E3CM24D is a 1000 A 3-pole open-transition motorised changeover switch with a 24 V DC motor supply and manual operating provision for high-current low-voltage power source transfer.
£5,302.71
The ABB OTM1000E3CM24D is a heavy-duty 1000 A 3-pole motorised changeover switch designed for controlled transfer between two electrical supplies in high-current low-voltage power distribution systems. Part of the ABB OT Changeover Switches range, it combines electrically operated source transfer with provision for manual operation.
The OTM1000E3CM24D provides open-transition changeover, maintaining electrical separation between alternative sources during transfer. Its integrated motor operator uses a 24 V DC control supply, making the switch suitable for remotely controlled and automated source-selection systems.
With a 1000 A AC-21A/AC-22A rating at up to 415 V, a rated apparent power of 680 kVA at 400 V and a 3-pole configuration, the OTM1000E3CM24D is designed for substantial three-phase installations. It is supplied with a handle for manual operation, an OTV1000ECMK operating handle assembly, M12 × 60 terminal bolt kit and male connectors for the control circuits.
Motorised changeover switches allow source-transfer operations to be performed electrically, enabling integration with remote controls, automation systems and transfer-control equipment. The ABB OTM1000E3CM24D combines a motor-driven mechanism with open-transition switching so that alternative supplies remain electrically separated during transfer.
The 24 V DC motor supply is particularly suitable for installations using low-voltage DC control circuits or battery-backed control systems. Manual operating provision remains available when local switching is required, giving the OTM1000E3CM24D flexibility for both electrically controlled and manual source-transfer duties.
