Schneider Electric XB5AD33 3-Position Selector Switch

XB5AD33: three-position maintained standard handle selector switch, 2 NO

The XB5AD33 is a Schneider Electric Harmony XB5 selector switch for a 22 mm panel hole. It has a black standard handle, three positions at ±45° spacing, a stay put action and two normally open (NO) contacts on a screw-clamp contact block. Seven Star LLC supplies the XB5AD33 in Oman and the GCC as an independent supplier based in Muscat, usually to panel builders, maintenance stores and EPC contractors who need a plain mode or command selector for a control desk or motor starter door.

The datasheet gives a descriptive title rather than an ordering table, so our reading of the code is an interpretation and not a manufacturer table: XB5 is the range, the letters after it identify a selector with a standard handle, and the digits stand for the number of positions, the return behaviour and the contacts fitted. Compare it with the siblings in the table below before you order.

XB5AD33 among the Harmony XB5 selector family

This unit belongs to a group of black selector switches that differ in positions, return action, contact count, handle length and, for the N-series, in range and ratings. Related references include XB5AD21N, XB5AD25, XB5AD33N, XB5AD41. The N-series references (XB5AD21N, XB5AD33N) belong to the XB5N/XB7N range, are packed 20 per unit and are rated IP65 and -25 °C.

Sealing, temperature and approvals of the XB5AD33

The datasheet lists IP67, IP69, IP69K protection with IK04 impact resistance, UL type 4X/13 enclosure type. Operation is rated from -40 to 70 °C and storage from -40 to 70 °C. Shock resistance is given as 30 gn for 18 ms and 50 gn for 11 ms, and vibration as 5 gn over 2 to 500 Hz.

Certifications listed for this reference: BV, UL, CSA, DNV, Lloyd’s Register (LROS). Marine classification marks appear in the datasheet for this reference, but accept them only against the current document supplied with the goods.

Technical specifications of the XB5AD33

Where XB5AD33 is used in Oman and the GCC

Selector switches of this type sit on motor control centre doors, pump and fan starter panels, water-treatment skids, crane and hoist pendants and packaged-equipment cabinets across the region. A maintained selector is the standard way to fix a mode such as local or remote. In oil and gas, power and desalination plants the sealed plastic head copes with dust, heat and humidity, and the ability to hose down the panel helps on coastal sites.

It is also a convenient spare to hold in a store, because one reference covers many identical starter panels.

Selection checklist and RFQ information for XB5AD33

Send the points below so that the part number can be confirmed against the datasheet and checked for availability in one reply.

• Part number XB5AD33 and the required quantity.
• Positions, return action and contacts you need: three positions, stay put, 2 NO.
• Handle length for your operators and operating environment.
• Panel thickness and hole size, against the 1 to 6 mm clamping range.
• Whether the project needs approvals beyond those in the datasheet.
• Delivery location in Oman or the GCC and the lead time you need.

How the XB5AD33 operates

Three maintained positions at ±45° give the this unit a left, centre and right state that all remain until the handle is moved. The classic uses are hand-off-auto on a motor starter, forward-off-reverse on a hoist or gate, and a three-way source or mode choice. The centre position is a true rest state, which is convenient when the middle setting means off.

The standard handle suits normal desk and door mounting and keeps the knob low enough that it is not caught by a passing sleeve. If the machine is operated in gloves, compare the long-handle references in the family table below.

Contact ratings and switching data of the XB5AD33

This unit carries two normally open (NO) contacts. With two NO contacts the three positions can drive two separate inputs, so left, centre and right can be told apart by a controller, or two circuits can be made independently.

The datasheet lists a conventional thermal current of 10 A, a rated insulation voltage of 600 V at pollution degree 3 and an impulse withstand of 6 kV, with short-circuit protection by a 10 A gG cartridge fuse. Operational currents are given by utilisation category:

• 3 A at 240 V, AC-15, A600
• 6 A at 120 V, AC-15, A600
• 0.1 A at 600 V, DC-13, Q600
• 0.27 A at 250 V, DC-13, Q600
• 0.55 A at 125 V, DC-13, Q600

The silver alloy (Ag/Ni) contacts have a rated electrical life of 1 million cycles at 2 A, 230 V, AC-15, and the mechanical life stated for the actuator is 1,000,000 cycles. Reliability at low signal levels is quoted at 5 V and 1 mA in a clean environment, which is useful when the contact feeds a PLC input rather than a coil.

Mounting and wiring the XB5AD33

This unit fits a 22.5 mm round hole (22.3 mm with +0.4/0 tolerance) with a clamping thickness of 1 to 6 mm per the datasheet drawing. The head measures 30 mm wide by 42 mm high and 70 mm deep behind the panel, and weighs 0.052 kg. The datasheet recommends an anti-rotation plate of type ZB5AZ902 for selector switches, so the handle torque does not turn the body in the hole.

Terminals are screw clamps for up to two conductors of 1.5 mm² with cable ends, or at least 0.22 mm² without ends; the recommended tightening torque is 0.8 to 1.2 N.m, and the screw heads accept Philips 1, Pozidriv 1 and 4 or 5.5 mm flat drivers. Allow wire bending space behind the panel before choosing a shallow enclosure.
