Eaton IEC 60947-3 Switch Disconnector QSA250N-2/3 250A Size 2

Eaton QSA250N-2/3 Switch Disconnector 250A IEC 60947-3 Details:

The Eaton QSA250N-2/3 is a strong fuse switch-disconnector made for dependable isolation in power distribution systems in factories. It has a frame size of 2 and a rating of 250A. It meets IEC 60947-3 requirements, which means it can safely work up to 690V AC.

This 3-pole switch disconnector works with NH1 and NH2 DIN fuse-links, giving you better protection against short circuits and overloads under tough conditions. Because of its solid neutral arrangement and back mounting style, it works well with switchboards, motor control centers, and heavy machinery. The QSA250N-2/3 is built to last, with silver-plated roller contacts for the best conductivity and double current interruption for further safety.

Applications

Use the Eaton QSA250N-2/3 in boats, factories, and power distribution boards where it’s very important to keep strong currents separate. It does a great job of keeping motors, transformers, and capacitor banks safe from problems, which is great for industries like shipping and manufacturing.

Usage Instructions:

• Place the device on a suitable rear panel in your switchboard, making sure it is aligned correctly so that the NH fuse can be inserted.
• Before turning on the circuit, put the right NH1/NH2 DIN fuse-links into the right slots.
• Manually turn the handle to the “ON” position to let power flow normally, making sure that no load is more than 250A.
• To keep things safe while you’re working on them or when something goes wrong, turn the switch to OFF and put on padlocks.

IEC 60947-3 Functions:

1) For three-phase circuits up to 250A, it provides safe load isolation and switching, making sure that power sources can be safely disconnected.

2) Includes NH1/NH2 fuse-links for full short-circuit and overload protection in industrial systems.

3) Lets you see the contact separation to make sure the device is OFF, which makes it easier to follow lockout/tagout safety rules.

4) Supports manual ON/OFF operation with the ability to secure the padlock, which keeps the machine from turning back on by accident while it is being worked on.

5) Allows for double-break per pole for effective arc quenching, which makes it last longer when switched on and off often.
