Schneider Electric EZC100F3020 Easypact EZC100F 20 A 3P Breaker

EZC100F3020: Easypact EZC100F 20 A thermal-magnetic breaker

The EZC100F3020 is an Easypact EZC100F molded case circuit breaker, three poles, with a TM-D thermal-magnetic trip unit rated 20 A at 50 °C. The datasheet gives 20 A at 40 °C as the rated current and lists both AC and DC networks. Seven Star LLC supplies the EZC100F3020 in Oman and the GCC as an independent supplier based in Muscat.

In this group of datasheets the EZC100F frame is offered at 20, 30, 40 and 50 A; the EZC100F3020 is the 20 A step. The reference is made of the family name EZC100F, the pole count 3 and the current in amperes, as the neighbouring titles show: EZC100F3020, EZC100F3030, EZC100F3040, EZC100F3050.

Size, mounting and connection of the EZC100F3020

The breaker is 130 mm high, 75 mm wide and 60 mm deep, mounted fixed on a backplate with front connections at top and bottom on a 25 mm pitch. The control is a toggle with positive contact indication, so the position of the contacts can be read from the handle.

The datasheet lists a mechanical durability of 13000 cycles and a protection degree of IP20 with IK07. IP20 is a finger-safe degree, so the breaker belongs inside an enclosure and not exposed in a hall.

Selection and RFQ checklist for the EZC100F3020

• Current: 20 A, checked against the load and the cable size.
• Network: AC or DC, and for DC the number of poles in series against the datasheet values.
• Fault level: 10 kA Icu at 400/415 V AC against the prospective current.
• Space: 130 mm high, 75 mm wide, 60 mm deep, in an enclosure suited to IP20.
• Accessories such as handles, locks and releases are separate references.

Breaking capacity and voltage limits of the EZC100F3020

The breaking capacity code is F. Ultimate Icu is 25 kA at 220 to 240 V AC and 10 kA at 400 to 415 V AC, with 7.5 kA at 440 V AC and 5 kA at 550 V AC. On DC the datasheet gives 5 kA at 125 V DC for one pole and 5 kA at 250 V DC for two poles.

Service capacity Ics is lower: 5 kA at 400/415 V AC and 12.5 kA at 220/230/240 V AC. Insulation voltage is 690 V AC 50/60 Hz and the impulse withstand is 6 kV, with the maximum operational voltage 550 V AC or 250 V DC.

Thermal-magnetic protection in the EZC100F3020

The TM-D trip unit gives overload protection through its thermal element and short-circuit protection through its magnetic element; the datasheet lists both under protection type. Adjustment values are not given on this datasheet, so any statement about threshold settings must come from the ordering documents.

The trip unit rating is 20 A at 50 °C, while the rated current is 20 A at 40 °C. As a worked example, a 20 A three-phase circuit at 400 V carries about 13.9 kVA, and a single-phase 20 A circuit at 230 V about 4.6 kVA. These are illustrative arithmetic, not datasheet values, but they help to judge if the breaker is sized close to the load.

EZC100F ratings around the EZC100F3020

The four references below share the frame, the trip unit type, the breaking capacity code and the dimensions; they differ in the rated current. Neighbours of the EZC100F3020 are EZC100F3030.

Where the EZC100F3020 fits in Oman and the GCC

A 20 A thermal-magnetic breaker of this type is typically found in small distribution boards, auxiliary supplies, pump and fan feeders, lighting and small-power circuits in commercial and industrial buildings, workshops and utility rooms. The datasheet operating range is -25 to 70 °C with storage at -35 to 85 °C.

In Oman, boards in plant rooms and in unshaded outdoor kiosks reach temperatures well above the reference temperature, so check the load against the temperature inside the enclosure. The datasheet lists pollution degree 3, a relevant point for dusty rooms and coastal humidity.

Choosing the 20 A step: the EZC100F3020 in practice

At 20 A this is the smallest step offered in the group. It suits short feeder circuits for lighting groups, small fans, socket circuits and control-panel supplies, where the cable is thin and tripping should happen early on overload. A lower rating also keeps the use-phase footprint in the datasheet the lowest of the four.

Pick it only if the continuous load, after allowing for the board temperature, is clearly under 20 A; for loads near the limit, the 30 A step is the next in the group.

The datasheet lists the single pack as 805 g, measuring 9.5 cm high, 8.5 cm wide and 14 cm long. Pack weights differ slightly between the four ratings in this group, which gives a quick way to check that a delivered box matches the reference.

The total lifecycle carbon footprint is given as 121 kg CO2 eq., of which 113 kg CO2 eq. is the use phase; the manufacturing phase is 7 kg CO2 eq. for all four references. The footprint grows with the current rating, and the use phase accounts for most of it.
