Schneider Electric ZBE101 Contact Block 1NO
Description
ZBE101: Harmony contact block with 1NO function
The ZBE101 is a Schneider Electric contact block for 22 mm Harmony XB4 and XB5 operators, carrying one normally open contact with screw clamp terminals. Seven Star LLC supplies the ZBE101 in Oman and the GCC as an independent supplier in Muscat, mainly to panel shops and maintenance stores that restock the contact side of push-button and selector stations.
The datasheet lists it as a contact block of the ZBE type, sold in packs of 5. Unlike the ZB5AZ bodies, a ZBE block carries no fixing collar of its own, so it is clipped behind the head together with a collar or on a body, and one pack is meant to cover several stations.
ZBE blocks in this lane and where ZBE101 sits
The eight blocks below share the Harmony XB4 and XB5 mounting but differ in contacts, terminals and ratings.
| Part | Contacts | Terminals | Remark from the datasheet |
|---|---|---|---|
| ZBE101 | 1 NO | Screw clamp | Standard, silver alloy |
| ZBE102 | 1 NC | Screw clamp | Positive opening |
| ZBE1013 | 1 NO | Faston | Ui 250 V |
| ZBE1015 | 1 NO | Push-in | Compact, Ui 300 V |
| ZBE1016 | 1 NO | Screw clamp | Gold flashed, low power |
| ZBE203 | 2 NO | Screw clamp | Double block |
| ZBE204 | 2 NC | Screw clamp | Double block, positive opening |
| ZBE205 | 1 NO + 1 NC | Screw clamp | Double block, positive opening |
Terminals and wiring of the ZBE101
Screw clamp terminals take up to two 1.5 mm² conductors with cable ends, or one conductor from 0.22 mm² without ends. The datasheet gives a tightening torque of 0.8 to 1.2 N.m for ZBE101 and screw heads that accept Philips or pozidriv No 1 drivers and flat 4 mm or 5.5 mm blades. Use ferrules on stranded wire so that no strand escapes the clamp.
The IP20 rating in the datasheet applies to the block itself, which sits behind the panel, so the sealing of the station against water and dust is provided by the head and the gasket. Keep insulation clearances in mind between neighbouring blocks, and label each block so that the terminal numbers in the drawing match the wiring.
Ratings, durability and environment
The datasheet lists operational currents of 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, with a thermal current of 10 A and a 10 A gG cartridge fuse for short-circuit protection. The insulation voltage is 600 V (pollution degree 3). The datasheet also states an electrical durability of 1,000,000 cycles at the quoted AC-15 and DC-13 conditions, for instance 2 A at 230 V AC. Mechanical durability is 10 million cycles for ZBE101, and the operating and storage range runs from -40 to 70 °C.
Vibration resistance is 5 gn (f= 2–500 Hz) and shock resistance reaches 30 gn for 18 ms and 50 gn for 11 ms. The certifications on the datasheet are CCC, UL, DNV, GOST, LROS (Lloyds register of shipping), BV, CSA. These apply to this exact reference only, so match any approval needed by the project against that list for this unit.
Stacking and combination with heads and bodies
A single block occupies one position behind the head. Several blocks can be clipped side by side on the same collar to build a multi-contact station, for example a 1NO block beside a 1NC block, and each contact then operates from the same push-button stroke. The single construction also makes it easy to replace one failed contact without touching the others.
The datasheet records the electrical composition codes C1 (quantity ≤ 9), C2 (≤ 7), C3 (≤ 6) up to C13, plus M1 (≤ 6), M2 (≤ 4), SF1 and MF1, which state how many blocks of this kind fit with each type of head or light block. For this unit, check the planned stack against these codes.
Typical uses in Oman and the GCC
Contact blocks such as this unit are held as maintenance spares by plants that run many Harmony stations: motor control centres, pump and fan starters, gate controls and packaged skids in oil and gas, power, water and desalination sites. In hot and dusty conditions the contact side is the part most likely to be worn first, so a stocked pack lets an electrician restore a station in minutes.

What the 1NO contact does
This is the basic make-on-press element. Typical duties are start, jog, acknowledge, test and raise commands, and it also serves as the signal contact of a selector or an emergency-stop head. The datasheet lists positive opening as ‘without’, so it is not the contact for a safety stop chain; use a normally closed block with the appendix K feature for that.
The contact changes state after 2.6 mm of travel out of 4.3 mm total, at an operating force of 2.3 N.
Information to send with an RFQ for ZBE101
The points below let us confirm the part number against the datasheet and check stock in one reply.
- Part number this unit and the number of packs.
- Contact arrangement required and whether a positive-opening contact is needed.
- Terminal style: screw clamp, faston or push-in.
- The control voltage and current to be switched.
- The head and collar the block will be used with.
- Delivery location and lead time.
A photo of the old block with its label visible helps us to confirm a like-for-like match.

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.
