Schneider Electric ZBE1013 Contact Block 1NO faston

ZBE1013: Harmony contact block with 1NO faston function

The ZBE1013 is a Schneider Electric contact block for 22 mm Harmony XB4 and XB5 operators, carrying one normally open contact with faston terminals. Seven Star LLC supplies the ZBE1013 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.

Terminals and wiring of the ZBE1013

The terminals of ZBE1013 are faston tabs: one 6.35 mm size and two of 2.8 mm. Receptacles with a matched crimp make a fast, vibration-resistant joint, but a poor crimp or an unsupported cable can loosen under vibration, so clip the harness close to the block.

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.

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 ZBE1013, check the planned stack against these codes.

Technical data of the ZBE1013

Typical uses in Oman and the GCC

Contact blocks such as ZBE1013 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.

Information to send with an RFQ for ZBE1013

The points below let us confirm the part number against the datasheet and check stock in one reply.

• Part number ZBE1013 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.

Ratings, durability and environment

For this reference the datasheet gives only an insulation voltage of 250 V (pollution degree 3), with no operational current table, so confirm the load with us before using the block on anything other than low-voltage control. Mechanical durability is 10 million cycles for this unit, 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 BV, UL, CSA, DNV, LROS (Lloyds register of shipping). These apply to this exact reference only, so match any approval needed by the project against that list for this unit.

What the 1NO faston contact does

This version replaces the screw terminals with faston tabs, which suits panels wired with crimped receptacles or looms made up in advance. The contact function is the same plain normally open duty, with positive opening listed as ‘without’.

The contact changes state after 2.6 mm of travel out of 4.3 mm total, at an operating force of 2.3 N. The datasheet for this reference does not give thermal current or operational current tables, only an insulation voltage of 250 V at pollution degree 3, so check the load against the manufacturer before assuming the ratings of the screw-terminal blocks.
