FAQs
Yes. The unit is designed for base mounting and uses screw terminals with a 50 mm width, allowing straightforward integration into standard switchgear or distribution panels. Tightening torque is specified at 50–75 N·m, ensuring reliable connections and consistent electrical performance.
This switch provides a conventional free-air thermal current of 1250 A (I_th), rated operational currents Ie across 380–415 V, 500 V, and 690 V up to 1250 A, a rated impulse withstand voltage Uimp of 12 kV, and a rated insulation voltage Ui of 1000 V. It supports high short-time current capability (Icw) of 50 kA for 1 s per pole, and a total of 710–1200 kW depending on voltage during AC-23A operation.
Yes. With 3 poles and an open transition (transition type Open), plus a front-operated mechanism and a 12 between-the-poles switching capability, it is well-suited for transfer switching in dual-source configurations, offering predictable operation and quick source changes in MCCs and distribution panels.
The product carries a CE Declaration of Conformity and RoHS compliance. It also has a DNV certificate for added verification in critical installations. Front protection is IP20, and RoHS status aligns with EU directive 2011/65/EU and amendment 2015/863.
The padlockable 0-position handle and door interlocks in I- and II- positions enforce lockout/tagout during maintenance, reducing the risk of accidental energization. This directly lowers safety incidents, minimizes unplanned downtime, and can shorten maintenance cycles, delivering a faster return on investment for panel-equipped facilities.
