ABB Disconnector OT25G1-3BS: control and safety for industrial and tertiary panels

The ABB disconnector OT25G1-3BS is designed for manual disconnection and securing of electrical circuits in distribution and automation panels. In practice, it allows for visible and reliable isolation of a line, load, or branch of a system, making maintenance operations and technical interventions safer. It is a typical solution in service panels, small machine panels, auxiliary lines, and sections of a system that need to be quickly de-energized.

The OT Plus family is appreciated for its robust construction and modularity, ideal when you want to keep the panel tidy and easily expandable.

3 poles and 25A: perfect for three-phase lines and dedicated loads

With a 3P configuration and conventional thermal current of 25A, the OT25G1-3BS is suitable for controlling and disconnecting three-phase lines and typical loads in the tertiary and light industrial sectors. It is a balanced choice when a compact but reliable disconnector is needed, capable of handling common nominal currents in secondary panels and sub-distributions.

DIN rail or plate mounting: versatile installation

The disconnector can be installed on a back plate or DIN rail, facilitating integration in both new panels and retrofits. This also simplifies standardization in stock: the same device can be used in different layouts, adapting to the panel's needs and available spaces.

Front operation and lockable handle: immediate control and safety

The front operation allows for immediate maneuvering from the front of the panel, useful in environments where quick and clear control is needed. The knob handle is lockable, an important element for safety procedures (lockout/tagout) and to prevent unauthorized reactivations during maintenance interventions. Practical note: external handle and operating shaft are not included, so they must be provided if using external control.

Data for panel use: operating mode and connections

The disconnector operates with front operation mode and provides line terminals with an arrangement that allows wiring from top to bottom (or vice versa, depending on the layout), facilitating conductor order in the duct. Pollution degree 3 places it in typical industrial/tertiary contexts where dust or more challenging environmental conditions than residential may be present.
