Switch Disconnectors |
The range from 16 to 160 Amp are either base plate or door mounted by snap-on or screw fitting. Front operated 3-, 4-, 6-, 8-pole and change over types are available as standard.
From 200 up to 3150 Amp the switch-disconnectors, also called load break switches, are designed as pole modules and they are available as 1- to 4-pole versions, front or side operated. |

Motorized Switch-Disconnectors |
| The switches can be operated either electrically by using the motor operator or manually by using the handle. The operation, either electrical or manual, can be chosen by the selector switch “Motor/Manual” on the motor operator. Motorized switch-disconnectors consist of the switch-disconnector (type OT) and the motor operator. The OTM range is for 160...2500 Amperes. |

Switch Fuses |
From 16 to 1250 Amp, up to 690V.
The switch fuse is used as the main switch in low voltage switchgears in the industry for distributing power and protecting motors, cables and other devices against short circuits and overloads.
The standard switch fuses withstand 100 kA fault current and they are available for all types of fuse links, DIN, BS, NFC, UL, CSA.
The range includes single pole to four pole versions, front- or side-operated. The pole module design enables location of the operating mechanism in any position together with the direction of the terminals giving flexibility to installation in different types of cubicle designs. |

Change-over and Transfer Switches |
| ABB’s change-over and transfer switches are tested according to IEC 60947-6-1 and IEC 60947-3 standards. The switches have ratings in AC31 and AC33 utilization categories, up to 415 V. In motorized switches, the motor operators have a wide voltage operation range |
