Schneider Electric ZENL1111 1NO Contact Block
Description
ZENL1111: single NO contact block for Ø22 stations
The ZENL1111 is a Schneider Electric single contact block with one normally open (1 NO) contact and screw clamp terminals. It is rear mounted behind a 22 mm control or signalling unit, and the datasheet names the Harmony XAL and XAPS ranges as its home. Seven Star LLC supplies the ZENL1111 in Oman and the GCC as an independent supplier in Muscat, usually to maintenance stores that need the exact contact function back in a push-button or control station.
On the datasheet generated on 8 Nov 2026 the ZENL1111 is not marked as discontinued. It is sold in packs of five, so a request for one contact still means a pack, and stock should be confirmed before a repair depends on it.
Contact action of the ZENL1111
This block carries a normally open contact, which closes when the operator is pressed. The datasheet states that positive opening is not provided, which is normal for an NO contact because there is nothing to force open. The contact changes state after 2.6 mm of travel out of a total travel of 4.3 mm, with an operating force of 2.3 N and an operating torque of 0.05 N.m. The action is slow-break.
An NO block is the right choice for start, run and acknowledge functions, where the circuit should only be energised while or after the button is pressed. For stop functions a normally closed block such as ZENL1121 is the usual companion, and the two are often stacked in a single station.
Typical use of NO contacts in Oman and the GCC
Contact blocks like ZENL1111 are replaced during maintenance on control stations, XAPS pendants and push-button panels in oil and gas, power and water plants. Dust, heat and humidity attack contacts over years, and the 10 A thermal rating with silver alloy contacts suits typical 24 V DC and 230 V AC control circuits. Start and acknowledge circuits are a common place for it.
Environment and standards
The ZENL1111 is rated IP20, so it is a component that depends on its station for enclosure protection. Operating and storage temperatures both run from -40 to 70 °C, and the protective treatment code is TH. Vibration resistance is 5 gn from 12 to 500 Hz, and shock resistance is 30 gn for 18 ms and 50 gn for 11 ms. Standards listed are IEC 60947-1, IEC 60947-5-1, IEC 60947-5-4, IEC 60947-5-5, UL 508, CSA C22.2 No 14 and the JIS C8201 parts. Compare them with the project list before ordering ZENL1111.

Switching ratings and life of the ZENL1111
The contact material is a silver alloy (Ag/Ni), and the maximum resistance across the terminals is 25 MΩ as stated on the datasheet. The conventional thermal current is 10 A and short-circuit protection is a 10 A gG cartridge fuse. Rated insulation voltage is 600 V in pollution degree 3, with a 6 kV impulse withstand. Mechanical durability is 10 million cycles.
| Voltage | Current | Utilisation category |
|---|---|---|
| 240 V | 3 A | AC-15, A600 |
| 120 V | 6 A | AC-15, A600 |
| 600 V | 0.1 A | DC-13, Q600 |
| 250 V | 0.27 A | DC-13, Q600 |
| 125 V | 0.55 A | DC-13, Q600 |
| 600 V | 1.2 A | AC-15, A600 |
The electrical durability entries are stated at one million cycles, for example AC-15 at 2 A and 230 V and DC-13 at 0.5 A and 24 V, at an operating rate below 3600 cycles per hour. The contact is also rated for dry-circuit duty, with a failure rate below 10-6 at 5 V and 1 mA in a clean environment.
Mounting the ZENL1111 in a station
The block is rear mounted and is assembled by the customer. The datasheet notes mounting on the integrated plate in the box, and the electrical composition codes SR1 (up to three blocks), SR2 (up to two blocks) and MR1 (up to two blocks) describe how many can be stacked. Terminals take up to two 1.5 mm² conductors with cable ends, or one 0.22 mm² or larger conductor without a ferrule, tightened to 0.8 to 1.2 N.m with a Philips or Pozidriv no 1 or a flat 4 or 5.5 mm blade.
Each block weighs 0.015 kg. After wiring, operate the head several times and check the contact with a meter before closing the station, because a block not fully latched on the plate gives intermittent contact. Replace this unit with a block of the same function, since swapping NO for NC reverses the logic of the circuit.
NO and NC blocks compared
ZENL1111 and ZENL1121 share the same body and terminals, and they differ in contact function and actuation figures.
| Item | ZENL1111 | ZENL1121 |
|---|---|---|
| Contact | 1 NO | 1 NC |
| Positive opening | Without | With, IEC 60947-5-1 appendix K |
| Travel at change of state | 2.6 mm | 1.5 mm |
| Operating force | 2.3 N | 2 N |
| Typical use | Start, run, acknowledge | Stop, interlock, fail-safe |
Information to send with an RFQ for ZENL1111
The points below let us confirm the part number against the datasheet and check stock in one reply.
- Part number this unit and quantity, noting the pack size of five.
- The station or head type it goes into (XB5 head, XAL or XAPS).
- Whether NO or NC is needed, and how many contacts are stacked.
- Control voltage and current of the circuit it switches.

About brand
Schneider Electric is the French group for energy management and industrial automation: low and medium voltage switchgear and circuit breakers, motor control, drives, PLCs, power monitoring, UPS systems and building management. Its history goes back to 1836, when the brothers Adolphe and Eugène Schneider took over the iron and steel works at Le Creusot in Burgundy. Over the 20th century the company left steel and heavy engineering and became an electrical group through acquisitions such as Merlin Gerin, Télémécanique, Square D and Modicon. Its head office is in Rueil-Malmaison near Paris, and its shares are listed on Euronext Paris.

Choosing Schneider Electric breakers and motor control
Circuit breakers are chosen by current and breaking capacity. Acti9 miniature circuit breakers (iC60, C120) protect final circuits up to 125 A. ComPacT NSX molded case breakers cover about 16 to 630 A, and the letter after the frame size sets the breaking capacity: B, F, N, H, S, L from lowest to highest. MasterPacT air circuit breakers are used as main incomers on large switchboards. For motors, a TeSys contactor with an LRD overload relay or a GV2 motor circuit breaker suits direct starting, an Altistart soft starter reduces starting current, and an Altivar drive controls speed. The breaking capacity must always be at least the prospective short-circuit current at the point of installation.
Where Schneider Electric products are used
In Oman and the GCC, Schneider Electric equipment is found in main and sub-main switchboards of commercial and residential buildings, motor control centres in water, oil and gas and industrial plants, substations protected by Sepam and Easergy relays, data centres powered by Galaxy and APC UPS systems, and buildings controlled by EcoStruxure Building Operation.
APC by Schneider Electric: UPS and critical power
Since 2007, APC has been part of Schneider Electric and is now its product brand for uninterruptible power supplies, replacement batteries, battery packs, network management cards and rack power distribution. Our APC catalogue covers Smart-UPS line-interactive and on-line models, Easy UPS On-Line, the modular Symmetra LX, RM and PX ranges, Silcon three-phase systems and their spare part kits, and the RBC cartridges that keep them running. Schneider Electric breakers, drives and PLCs can be quoted together with APC UPS systems in one request.
