Schneider Electric XA2EVF4LC Red 110 V AC/DC LED Pilot Light

XA2EVF4LC: red 110 V AC/DC Harmony XA2 LED pilot light

The XA2EVF4LC is a Schneider Electric Harmony XA2 monolithic pilot light for a 22 mm panel hole, with a red round cap, a built-in clustered LED and a rated supply of 110 V AC or DC, 50/60 Hz. Seven Star LLC supplies the XA2EVF4LC in Oman and the GCC as an independent supplier based in Muscat, usually to panel builders, maintenance stores and EPC contractors who need indicators that match an existing control scheme.

Unlike a lamp-holder design, this unit is monolithic: the LED and its supply electronics are sealed inside the body, and the datasheet lists the bulb base as none. There is no lamp to change, which is the main practical difference from older incandescent indicators. A reading of the reference that fits the datasheet titles of its siblings is XA2EV for the family, F for the supply group, 4 for the red cap and LC for the anti-interference electronics version; this is our interpretation, not a published ordering table.

Technical specifications of the XA2EVF4LC

Supply voltage and LED behaviour

The 110 V AC/DC rating is the flexible member of the range. One lamp runs from a 110 V AC control transformer secondary or from a 110 V DC battery or rectified supply, so a panel that mixes both supplies, or a plant that is migrating from one to the other, can keep a single part number for these indicators. The datasheet lists the supply as 50/60 Hz.

The datasheet gives the supply limits as 0.8 to 1.2 times the rated value, which for XA2EVF4LC works out to roughly 88 to 132 V. Within that window XA2EVF4LC gives a signalling type that is steady, and its current consumption is stated as not more than 20 mA. The light source is a clustered chip-on-board LED, and the quoted service life is 40000 h at rated voltage and 25 °C, so continuous duty of XA2EVF4LC in a normally ventilated panel is the intended use. Driving the lamp at the top of its voltage window or in a hot enclosure will shorten that figure, as with any LED.

The XA2EV LC family and how XA2EVF4LC differs

The lamps in this lane share the same 29 mm head, the same IP65 rating and the same 40000 h LED life, and are separated by supply and colour. That makes selection a two-step choice: first the supply that matches your control circuit, then the colour that matches your panel legend. XA2EVF4LC sits in the 110 V AC/DC group with a red cap.

Selection checklist and RFQ information for XA2EVF4LC

For a clean enquiry, send the information below. It lets us confirm the part number against the datasheet and check availability without a second round of questions.

• Part number XA2EVF4LC and the required quantity.
• The control supply: confirm 110 V AC or DC, 50/60 Hz and whether it is AC or DC.
• The lamp colour and its meaning in your panel legend.
• Panel thickness and material at the fixing hole, to match the 1 to 6 mm or 2 to 6 mm window.
• Rear clearance behind the panel, against the 53 mm body depth.
• Required markings or approvals for the project, so that we can compare them with the datasheet listing.
• Delivery location in Oman or the GCC and any required lead time.

If you are replacing an existing indicator, a photo of the old lamp and its rating label is the fastest way to confirm a like-for-like match.

Mounting, cut-out and wiring of the XA2EVF4LC

The XA2EVF4LC mounts in a round fixing hole of 22.5 mm with a tolerance of 0.2 mm in either direction, in line with IEC 60947-5-1. The datasheet recommends a fixing centre of at least 30 × 40 mm and quotes a panel thickness of 1 to 6 mm for metal and 2 to 6 mm for plastic. A single nut beneath the head clamps the unit, and the recommended tightening torque is 2.2 N.m with a tolerance of 0.2 N.m. Over-tightening can distort a thin panel and spoil the seal, so use a torque tool on the first panel of a batch.

Connection of XA2EVF4LC is by screw clamp terminals. The datasheet allows up to two conductors of 1.5 mm² with cable ends, or a single conductor from 0.5 to 2.5 mm² without ends, and the screw heads accept a Philips No 2 driver or a flat 4 mm or 5.5 mm blade. The terminals are marked X1 and X2, and the overall body is 29 mm wide and 29 mm high with a depth of 53 mm behind the panel, so check the space behind the door before stacking a row of lamps close to a busbar or a terminal rail.

Installation, commissioning and maintenance notes

Before energising XA2EVF4LC, confirm that the supply on its terminals is the rated value and not a higher panel voltage, and that no neighbouring wiring is pinching the rear terminals. Switch on and check that this unit lights at the right moment in the sequence, then check that it is fully dark when the circuit is de-energised, which also confirms that the anti-interference design is doing its job on your cable length.

Where a red lamp belongs on the panel

Red is the colour operators watch for first, and standards-minded panel builders reserve it for faults, trips, danger and emergency conditions, or for a stopped state when the plant specification says so. Using red for a harmless indication dilutes its meaning, so check the project colour table before assigning this lamp to a duty. The this unit follows this red convention.

Typical uses in Oman and the GCC

Indicators of this class, including this unit, turn up on motor control centres, pump and fan starters, water treatment skids, switchgear doors and packaged equipment panels throughout the region. In oil and gas and petrochemical sites they appear on auxiliary panels and local control stations; in power and desalination plants they mark pump status, valve position and supply healthy. Municipal buildings, cold stores and workshops use them on distribution boards and machine panels.
