Product details

A TPMO (Triple Pole Manually Operated) switch, also known as an A.B. (Air Break) switch, is a type of outdoor switch used in high-tension (HT) power lines for manually switching on/off the current flow. It's a gang-operated switch, meaning all three poles are operated simultaneously by a single handle. These switches are crucial for isolating sections of the power line for maintenance or in case of faults.

Frequently asked by buyers

Can the TPMO/DO switch be used for three-phase HT power lines only?

Yes, the TPMO/DO switch is specifically designed as a triple pole device to simultaneously isolate all three phases of a high-tension power line.

Does the TPMO/DO switch require power for operation?

No, this is a manually operated switch that functions without the need for electrical power, relying solely on mechanical gang operation.

Is the TPMO switch suitable for outdoor installations?

Yes, the TPMO/DO switch is constructed using weatherproof and corrosion resistant materials making it ideal for outdoor high voltage environments.

What is the main function of the TPMO/DO switch in high-tension power lines?

Its main function is to manually isolate a section of the power line to allow safe maintenance or fault clearance by interrupting current flow on all three poles simultaneously.

Are TPMO/DO switches standardized for rated voltage and current?

While the basic design is consistent, specific rated voltage and current values may vary by manufacturer and model and should be confirmed before procurement.
