TPH3-125 DIN Rail Isolating Switch for Electrical Isolation
High-performance electrical isolating switch for safe disconnection and maintenance isolation in low-voltage distribution systems.
The TPH3-125 DIN rail isolating switch is designed for safe and reliable electrical isolation in low-voltage power distribution systems. Suitable for AC 50/60 Hz, 230/400 V circuits with a rated current of up to 125 A, it is intended for no-load switching and for isolating the power supply during maintenance and servicing. The rail-mounted design enables fast installation in distribution boards and improves overall installation efficiency. Complying with IEC 60947-3, it is widely used in residential, commercial, and industrial applications.
