ODM HD13BX Single Throw Rotary Knife Switch Factory, Company

The HD13BX Single Throw Rotary Knife Switch provides reliable circuit isolation for industrial power systems, supporting 100A-2000A loads at AC380V with 1000V insulation. This single-throw rotary switch features a smooth rotating mechanism for precise operation, alongside high making/breaking capacity (up to 1500A) and short-time withstand currents up to 30kA. With 10,000 mechanical cycles and low operating force (≤400N), the HD13BX switch ensures durable performance in 50Hz applications. Its compact design and central handle operation make it ideal for distribution panels requiring safe, manual isolation and maintenance-free reliability.

Frequently Asked Questions

QWhat does the "BX" designation mean in HD13BX?

The "BX" marking indicates that the switch uses a rotary operation mechanism, whereas models without "BX" employ a standard lever operation mechanism.

QWhat are the standard operational voltages and insulation ratings?

The HD13BX knife switch series operates at a rated voltage of AC 380V, with a high insulation voltage rated up to 1000V.

QHow are arc extinguishing devices identified in the product code?

The arc suppression capability is noted in the code: "0" indicates that the unit comes without an arc extinguishing device, while "1" confirms the presence of an arc extinguishing device.

QWhat pole configurations are supported by the HD13 series?

The series is designed to accommodate various installation configurations and is available in 1-pole, 2-pole, 3-pole, and 4-pole versions.

QWhat is the mechanical endurance life cycle of these switches?

Depending on current capacity specifications, the mechanical life ranges from 3,000 operations for larger units (2000A) up to 10,000 operations for units rated between 100A and 400A.

QWhat is the difference between front and rear terminal connections?

For central handle configurations, a "8" in the designation specifies front terminal wiring, while "9" specifies rear terminal connection. If neither is listed, standard front terminal wiring is standard.
