Schneider Electric A9F93220 iC60L 2P 20A B Circuit Breaker

A9F93220: two-pole 20 A B-curve miniature circuit breaker

The A9F93220 is a Schneider Electric Acti9 iC60L miniature circuit-breaker, listed in the datasheet as iC60L – miniature circuit breaker – 2P – 20A – B curve. The datasheet lists the application as Distribution, a thermal-magnetic trip unit and network type DC / AC. The datasheet gives a breaking capacity of 50 kA Icu at 220–240 V AC under EN/IEC 60947-2 and also lists 380–415 V AC and 440 V AC bands. Seven Star LLC supplies the A9F93220 in Oman and the GCC as an independent supplier based in Muscat.

The datasheet for this reference carries the date 8 Nov 2026 and does not state a lifecycle status, so confirm availability before ordering. A 20 A rating fits heavier appliance and equipment circuits, small compressors and groups of fan-coil or pump loads. The datasheet also lists compatibility with add-on residual current devices: Vigi iC60 single terminal add-on residual current device 25/40/63 A; Quick Vigi iC60 single terminal add-on residual current device 25/40 A.

Technical specifications of the A9F93220

2P construction of the A9F93220

As a two-pole device, it opens two conductors together, typically phase and neutral of a single-phase circuit or two phases of a line-to-line load, and occupies four 9 mm pitches (36 mm) of rail. Both poles are tied by the common handle, so a fault on either one opens both. Compared with two single-pole units it also gives a cleaner, shorter busbar arrangement in the board.

Net weight is 0.25 kg and the body is 36 mm wide, 85 mm high and 78.5 mm deep, so a panel layout should reserve 36 mm of rail per device plus a small gap for heat when several breakers sit side by side.

Breaking capacity of the A9F93220 by voltage band

Breaking capacity is the figure that decides whether a breaker can be installed at a given point of the network. Icu is the ultimate capacity; Ics is the service capacity, expressed as a share of Icu, after which the device is still expected to remain serviceable. For the A9F93220 the datasheet lists the following.

The datasheet adds a rated short-circuit capacity Icn of 15000 A at 400 V AC 50/60 Hz under EN/IEC 60898-1, the household-standard rating. The limitation class is 3, which describes how strongly the device limits the let-through energy of a short circuit. Compare these values with the prospective fault current at the installation point; if the supply side can exceed them, the design needs a higher-rated device or upstream back-up protection.

The A9F93220 within the iC60L B-curve listing

No other 2P reference of this curve appears in this listing, so the A9F93220 stands alone at its pole count here. The table lists every reference of this device and curve that appears in our catalogue range.

Where the A9F93220 is used in Oman and the GCC

In Oman and the GCC the iC60 family appears in commercial buildings, industrial distribution boards, utility auxiliary panels and process cabinets. The A9F93220 fits circuits where a 20 A two-pole B-curve breaker with this fault capacity is needed in a compact 9 mm module. Gulf plant rooms combine heat, dust and humidity; the datasheet gives operation from -35–70 °C, relative humidity of 95 % at 55 °C and tropicalisation class 2, so site conditions should be compared against these limits and against the derating practice of the board builder.

Information to send with an RFQ for the A9F93220

• Full reference (this unit) and quantity
• Supply voltage, frequency and AC or DC use at the installation point
• Prospective short-circuit current and the load or cable the breaker protects
• Existing board, rail and neighbouring devices, including any add-on residual current device
• Delivery location, timing, and whether the order is a spare or a new installation

Installation and maintenance of the A9F93220

This unit clips onto a rail; the datasheet lists the mounting mode as clip-on. Strip conductors to 14 mm and tighten terminals to 2 N.m, using a calibrated screwdriver. Terminals accept 25 mm² rigid and 16 mm² flexible conductors at either the top or the bottom. The datasheet lists suitability for isolation, so the open breaker can serve as a disconnection point; follow the site lock-out procedure when working downstream.

Check periodically that the trip indicator is clear, that the handle moves freely and that terminals have not discoloured. Mechanical durability is 20000 cycles and electrical durability is 10000 cycles. A device that has cleared a heavy fault should be inspected and replaced rather than assumed intact.

Using a 20 A rating: what the A9F93220 protects

Mid-range ratings are the everyday workhorse of final distribution. The designer usually chooses them from cable section and from the expected continuous load, then checks that the earth-fault loop impedance allows the instantaneous magnetic trip to operate.

The B curve trips magnetically at 4 × In ± 20 %, the most sensitive of the common curves. It is chosen in general practice for long cable runs, weak supplies or generator-fed circuits where the available fault current is low, and for resistive loads with almost no inrush.
