2 | Disconnect switches - Nonfusible & fusible

ABB is committed to offering high quality and innovative

low voltage products. ABB’s disconnect switch lines are no

exception.

Modern materials and manufacturing technology coupled with

advanced features allow ABB’s disconnect switches to offer

superior customer benefits – exceptional performance, easy

installation, and ultimate protection – like no other. Through

a broad range of product offerings, ABB sets the standard for

disconnect switches industry-wide.

The disconnect switch is largely used in low voltage switchgear

for distribution of power, for starting and stopping motors

and for isolating loads during maintenance. ABB’s range of

disconnect switches are suitable for diverse applications, in

motor control centers, in switchboards and as main switches in

various equipment and machinery.

The disconnect product line ranges from standard 3-pole

configurations to specialty combination switches for transfer,

bypass and reversing. The comprehensive ABB range of Low

Voltage Disconnect Switch products is the perfect choice for

all switching applications.

Disconnect switches are integral to ABB’s line of circuit

protection devices to guard against equipment damage in

multiple applications. ABB prides itself in being the Safety

Pioneer for the low voltage electrical product industry as our

products offer maximum protection of the electrical installation

and the user. Designed to meet customer requirements for

safety, ABB’s disconnect switch lines feature:

Fingerproof construction – IP 20

Switches

Dead-front construction plus terminal shrouds reduce the

risk of touching live parts.

Padlockable mechanisms & handles

Handles can be padlocked in the OFF position with up to

three padlocks. Additionally, the switch mechanism can

be directly padlocked in the OFF position when the door is

open.

Welded contact protection

Positive opening operation safeguards users in case of

welded contacts due to an extreme overcurrent situation.

The ABB switch design cannot reach the OFF position

unless the contacts are truly open. This safeguards the user

by alerting them of the problem, maintains door interlock

safety and does not allow a padlock to be inserted.

Track resistant material

Excellent track resistant material reduces the risk of flashover

between phases even in the most severe circumstances.

Door Interlock

The handle and shaft provide door interlock so that the door

cannot be opened when the switch is in the ON position.

Clear position indication

All ABB disconnect switches and handles are clearly marked

with ON and OFF designations, which allow for quick position

identification whether the door is open or closed.
