Schneider Electric XB7ND33 3-position Selector Switch

Product Description

The SCHNEIDER ELECTRIC XB7ND33 is a 3-position maintained selector switch designed for industrial control panel applications. It features a black knob operator with a 22 mm panel mount hole diameter and a 2NO contact configuration rated at 0.6 amps. The maintained action holds its selected position until the operator is physically moved, making it well-suited for mode selection and equipment control circuits. Installation is handled by licensed electricians and qualified control panel technicians. The XB7ND33 meets multiple international standards including UL 508, CSA C22.2 No. 14, and EN/IEC 60947-5-1, confirming suitability for demanding industrial environments.

This selector switch is used in industrial and commercial control panel builds and retrofits where a non-illuminated, panel-mount operator is required. Typical applications include machine tool controls, motor starters, HVAC equipment control panels, and process automation enclosures. Its shock-resistant and vibration-resistant construction makes it appropriate for installations subject to mechanical stress. The screw clamp terminal type allows for secure wiring connections in panel environments. NEMA 12 and NEMA 3 ratings indicate suitability for indoor dust-tight and outdoor use cases where drip protection is needed.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC and applicable local codes. De-energize and lock out the control panel before removing or installing any operator switch. The 22 mm panel hole must be cut to specification before mounting. Confirm terminal torque and wiring requirements against the panel schematic before energizing.
