What is this selector switch head used for?

This component is the operator head for a 22 mm Harmony XB5 selector switch assembly. It provides the front-panel handle that an operator turns to change the switch position, while the switching function is handled by the compatible selector switch body and contact blocks mounted behind the panel.

Is the operator momentary or maintained?

It is a maintained (stay-put) operator, meaning it remains in the selected position until it is intentionally turned to the other position.

How many positions does it have and what is the switching angle?

It is a 2-position operator with a 90° indexing between positions.

What panel mounting size does it fit?

It is designed for standard 22 mm panel mounting (22 mm mounting diameter). For finished panel holes, a Ø22.5 mm cut-out is commonly recommended, with typical tolerance guidance of Ø22.3 mm (0/+0.4) depending on the installation standard used.

What does “long handle” mean for installation and operation?

The long handle provides greater leverage and a more prominent operator profile on the panel, which can be helpful when the selector needs to be easily gripped or clearly distinguished from nearby devices.

What colour and materials are used on the front of the operator?

The operator handle is black, and the bezel is plastic (dark grey plastic bezel material is specified for the assembly).

Can the operator be padlocked in position?

No. This operator is specified as non-padlockable.

What environmental protection ratings does it offer when correctly installed?

When assembled and installed correctly as part of the Harmony XB5 system, it supports high ingress and impact protection ratings including IP67, IP69 and IP69K, plus NEMA 13 and NEMA 4X, and an IK06 impact rating.

What operating and storage temperature range is specified?

Typical specified ambient temperature range is -40°C to +70°C for both storage and operation.

How durable is the mechanism for frequent use?

Mechanical durability is specified at up to 1,000,000 operating cycles for the operator head as part of the intended assembly.

Which operator head shape and style does it have?

It uses a round head style with a standard head type and a maintained selector handle operator profile.

Is it compatible with Harmony control stations for multiple cut-outs?

Yes. It is referenced for use with Harmony control stations such as XALD (1 to 5 cut-outs) and XALK (2 to 5 cut-outs), subject to using the correct selector switch body and contact block configuration behind the panel.

Are there any common installation accessories recommended for selector switches?

For selector switches, an anti-rotation plate is commonly recommended to help prevent the operator from turning in the panel cut-out under repeated use (for example, Schneider accessory type ZB5AZ902).

Which key standards is it designed to meet as part of the Harmony XB5 range?

Typical listed standards for this type of Harmony XB5 selector switch head include IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, UL 508, CSA C22.2 No 14, and relevant JIS standards, depending on the overall assembled device and installation.

What else is required to make it a functioning selector switch?

This item is the operator head only. To create a complete, working selector switch, you will also need the compatible Harmony XB5 selector switch body and the required contact block(s) for your circuit.
