Frequently Asked Questions

What cable sizes can I connect to the OT100G2-3BS isolator?

The OT100G2-3BS accepts flexible copper cables ranging from 1.5mm² to 35mm² and solid copper cables from 1.5mm² to 6mm². The screw terminals should be tightened to 2Nm torque for optimal electrical connection and to prevent damage from over-tightening.

Can this isolator be mounted on both DIN rail and base mounting?

Yes, the OT100G2-3BS features dual mounting capability, supporting both base mounting and DIN rail installation. This flexibility allows integration into various panel configurations and existing installations. The compact G2 frame dimensions of 91.5 x 52.5 x 73mm ensure efficient use of panel space regardless of mounting method.

What is the difference between the OT Plus range and previous ABB isolator ranges?

The OT Plus range offers enhanced compatibility with existing OT accessories, including full compatibility with existing OT shafts and external handles. The padlockable direct mounted handle provides improved safety features for lockout/tagout procedures while maintaining the compact design philosophy of previous generations.

What loads can the OT100G2-3BS handle in three-phase applications?

With a 100A current rating and 45kW rated power (AC-23A category), this three-pole isolator can handle substantial three-phase loads including motor circuits, heating systems, and distribution applications. The AC-23A rating specifically indicates its suitability for other loads including resistive and mixed load applications in three-phase systems.

Is the OT100G2-3BS suitable for outdoor installations?

The IP20 protection rating makes this isolator suitable for indoor installations and electrical enclosures but not for direct outdoor exposure. For outdoor applications, the isolator should be housed within an appropriately rated electrical enclosure that provides adequate weather protection and maintains the required ingress protection standards.
