The Tesla DCO4P63 4 Pole 63A DIN Rail Changeover Switch delivers a safe, robust, and standards-compliant solution for switching between two power supplies in three-phase applications. With its centre-off functionality, reliable build, and flexible mounting, it is a must-have for backup power and load management systems.

Q: Is the Tesla DCO4P63 suitable for switching all three phases and neutral?
A: Yes, it is a 4-pole switch, making it suitable for 3-phase + neutral configurations.

Q: What does centre-off mean?
A: The centre-off position provides a neutral state between two power sources, allowing for safe disconnection before switching.

Q: Can this be used for inductive loads like motors?
A: Yes, it is rated for AC22A, which supports moderately inductive loads such as motors.

Q: Do I need a professional to install it?
A: Yes, installation should always be performed by a licensed electrician, especially in three-phase systems.

All products must be installed by a licensed electrican. DIY electrical work is illegal and very dangerous.
