Schneider Electric EZ9F51106 Easy9 1P 6A C Circuit Breaker

EZ9F51106: single-pole 6 A C-curve Easy9 breaker

The EZ9F51106 is a Schneider Electric Easy9 miniature circuit breaker, a single-pole 6 A device with a C trip curve and a thermal-magnetic trip unit for 230 V AC networks. The datasheet gives a breaking capacity of 10000 A Icn under IEC 60898-1, a modest fault level that suits final distribution boards rather than boards fed close to a large transformer. Seven Star LLC supplies the EZ9F51106 in Oman and the GCC as an independent supplier based in Muscat.

The datasheet is dated 8 Nov 2026 and carries no discontinuation notice. A 6 A rating is the classic lighting-circuit size. It also covers small control power supplies, indicator feeders and light fan units on thin conductors. This page concentrates on what the datasheet states rather than on options it does not list, such as add-on residual current blocks or auxiliary contacts.

Technical specifications of the EZ9F51106

Where the EZ9F51106 is used in Oman and the GCC

Easy9 breakers appear in residential and commercial buildings, small workshops, camps and the auxiliary circuits of larger plants. The EZ9F51106 suits a 6 A single-phase outgoing way where cost and simplicity matter and the fault level is modest. Gulf sites add heat and dust, so mount the board in a ventilated, enclosed location, keep within the temperature limit in the table above, and consider derating when many breakers sit together in a hot room.

Environmental, packaging and warranty data for the EZ9F51106

The datasheet lists operation from -5–60 °C, storage from -40–85 °C and relative humidity of 95 % at -5–60 °C. Protection degree is IP20 and pollution degree 2, so installation inside a clean, enclosed board is assumed. The contractual warranty is 18 months.

What the 6 A rating and C curve mean for the EZ9F51106

A 6 A rating is the classic lighting-circuit size. It also covers small control power supplies, indicator feeders and light fan units on thin conductors. Within this batch the EZ9F51106 represents the lightest circuit. The datasheet states a magnetic tripping limit of 5–10 x In, so for 6 A the instantaneous region lies roughly between 30 A and 60 A. Anything above that band should clear within the magnetic element; slower overloads are handled by the thermal element, which is why a motor starting current of moderate duration does not normally trip it.

Short-circuit performance follows the same logic. With 10000 A Icn at 230 V AC and 400 V AC and a service capacity of 7500 A (75 % of Icn), the breaker fits boards fed from the public-network-size supplies it was designed for. If the transformer behind the board can deliver more prospective current than that, a different range is needed.

Single-pole layout and terminals of the EZ9F51106

A single-pole breaker interrupts only the phase conductor, so the neutral stays connected and the load must be wired accordingly. The body is 18 mm wide, 81 mm high and 66.5 mm deep, using 2 pitches of 9 mm, which allows many devices to be mounted side by side on one DIN rail row.

Tunnel terminals at top and bottom accept 25 mm² rigid and 16 mm² flexible conductors. Strip 14 mm and tighten to 2 N.m. Terminal range and torque can differ between siblings, so confirm the numbers on the family table rather than assuming one standard value.

Installation and maintenance of the EZ9F51106

The this unit clips onto DIN rail. Isolate the supply, strip the conductor to the stated length, insert it fully into the tunnel terminal and tighten with a calibrated screwdriver. Keep the conductor cross-section within the range for the terminal; a flexible conductor should be dressed neatly, and a ferrule is good practice even though the datasheet gives only the cross-section range.

Mechanical life is 20000 cycles and electrical life 4000 cycles, so frequent switching under load is not what this device is for. At service, check that the handle moves freely, that terminals are not discoloured and that the contact position indicator matches the handle. Replace a breaker that has cleared a heavy fault.

The EZ9F51106 among Easy9 single-pole C-curve references

The nearest siblings by rating are EZ9F51110 (10 A) and EZ9F51116 (16 A). They share the 18 mm housing and the 10000 A breaking capacity; what changes is the thermal setting, the terminal capacity and the weight. The table lists the six single-pole references in this batch.
