Rated continuous current Iu is 63 A, with a rated insulation voltage Ui of 800 V and a maximum rated operational voltage of 690 V AC (50/60 Hz) or 500 V DC. It carries no overload or short-circuit protection — this is a disconnect-only device, not a circuit breaker, intended for isolation and switching duty where protection is handled upstream or by a separate release.
The 63 A continuous rating (Iu) sets the maximum load current the disconnector can carry without exceeding its thermal limits — sized for a 63 A feeder or motor branch. The 800 V insulation voltage (Ui) and 690 V AC / 500 V DC operational voltage cover standard 400 V three-phase panels and DC bus applications up to 500 V. The 2 kA limited short-time withstand (1 s and 0.5 s) means it can hold off fault current for that duration while an upstream breaker clears; it is not rated for making or breaking fault current on its own. The UVR does not have a leading contact, so it cannot signal an impending trip to a controller before the disconnector opens. The HQ designation means high-quantity switching — rated for frequent operation in control circuits.
The disconnector measures 130 mm high, 76.2 mm wide, and 70 mm deep — a compact footprint for a 63 A MCCB-style device. Main circuit connections are front-terminal busbar connections (nut keeper kit included), which simplifies busbar stacking in a panel. An optional motor drive is available as a field-installable accessory, enabling remote switching via a PLC or building management system.
