Load switch OT630E03DP 3-pole 630A

The OT630E03DP switch-disconnector is a robust solution for low-voltage applications, engineered to meet stringent performance criteria. It offers a rated operational current of 630 A across AC-21A, AC-22A, and AC-23A categories at voltage levels ranging from 380 V to 690 V. This model supports DC operation with a rated current of 600 A at up to 1000 V. Designed in compliance with IEC/EN 60664-1 and IEC 60947-3 standards, it achieves a rated insulation voltage of 1000 V and an impulse withstand voltage of up to 12 kV.

 

The switch-disconnector features six poles (6P) with lug terminals accommodating tightening torques between 50 and 75 N·m as per IEC requirements. Mechanical durability is rated for up to 10,000 operations under normal use conditions. Power loss is contained at approximately 25 W per pole during standard operating conditions.

 

Suitable for environments up to pollution degree III and offering front-side IP00 protection, this device ensures reliable performance even in challenging industrial settings. Rated short-circuit conditions include making capacities of up to 80 kA at 690 V when paired with an appropriate fuse configuration. Its thermal ratings include conventional free-air currents (Ith) and enclosed thermal currents (Ithe) maintained at the maximum operational value.

 

Physical dimensions are optimized for installation flexibility: net width of the unit is specified as 311 mm, depth as 280 mm, height as approximately 250 mm, and weight as 13.8 kg—all conducive to streamlined integration into electrical panels or machinery systems where space-conscious design matters.

 

This disconnector supports high power transfer capabilities for motor control or power distribution applications including AC loads up to 630 kW (at voltages ≤690 V).
