Schneider Electric A9S60220 Acti9 iSW 2P 20 A Switch

A9S60220: Acti9 iSW 2P, 20 A switch-disconnector

The A9S60220 is a Schneider Electric Acti9 iSW modular switch, listed by the manufacturer as: switch Acti9 iSW – 2 poles – 20 A – 415V. It is a manual on/off device for DIN rail panels. It switches and isolates a circuit by hand and carries no overload or short-circuit element, so it always works together with a miniature circuit breaker or fuse upstream. Seven Star LLC supplies the A9S60220 in Oman and the GCC as an independent supplier in Muscat.

The reference reads as follows: Acti9 is the modular device range, iSW is the switch-disconnector line, 2P gives the number of poles and the 20 A figure is the rated operational current at 415 V. The category is AC-22A. The two-pole 20 A version occupies only two 9 mm modules, 18 mm in total, which makes it the natural local isolator for a single-phase final circuit: a lighting group, a small extractor fan, a water heater or a split air-conditioner outdoor unit fed from a distribution board.

Technical specifications of the A9S60220

How to read the ratings of the A9S60220

Utilisation category AC-22A means the switch is built for resistive and mixed inductive loads including moderate overloads, so the 20 A rating at 415 V applies to circuits of that kind. The insulation voltage of 500 V AC conforming to EN/IEC 60669-2-4 and the impulse withstand of 4 kV describe how the switch behaves with respect to the supply and overvoltages, and they are different from the operating voltage.

A switch-disconnector has no tripping element. If the load is a motor, remember that the starting current is several times the running current, so the switch must be backed by a proper starter or a motor-rated device; the A9S60220 is a means of switching and isolating, not of protecting. Two poles mean line and neutral are both opened, which is what you want on a single-phase circuit. On a three-phase load it is the wrong choice, and 20 A at 415 V in AC-22A is the limit, so motors with a high starting current need a dedicated starter and not just this switch.

Acti9 iSW references compared with the A9S60220

Its 32 A two-pole sibling A9S60232 has the same body and terminals, so the choice between the two is purely about the load current and the upstream protection.

Size, terminals and wiring of the A9S60220

The A9S60220 measures 77 mm high, 18 mm wide and 70 mm deep, which is 2 modules of 9 mm on the DIN rail and weighs 66 g. It is fixed-mounted on a DIN rail and finished in white. The toggle gives a clear ON/OFF indication, and the contact position is signalled.

Terminals are specified as tunnel type terminals: 10 mm² rigid; 10 mm² flexible; 10 mm² flexible with ferrule. The stripping length is 9 mm and the tightening torque 1.2 N.m, so use a torque screwdriver for repeatable connections. Keep conductor cross-sections within the stated 10 mm² limit.

Installation and maintenance of the A9S60220

Snap the A9S60220 onto the DIN rail, connect supply and load as shown by the markings on the device and the wiring diagram, and tighten to 1.2 N.m. Switch it on and off a few times without load to confirm the toggle movement and the position indication. Label the circuit clearly, because the whole purpose of the switch is to give a maintenance person a known point of isolation.

In service, look for heat marks near the terminals and re-check torque after the first weeks. The listed electrical durability of 30000 cycles refers to switching under load, so a switch that is operated frequently under load wears sooner than one that is only used for isolation.

Selection checklist for the A9S60220

Before ordering the A9S60220, confirm the following.

• Load current at the supply voltage: 20 A at 415 V.
• Number of poles: 2P, and whether the neutral must be switched.
• Upstream protection: the switch needs a breaker or fuse sized for the cable and the fault level.
• Space: 2 modules of 9 mm, 18 mm wide.
• Terminal cross-section and number of conductors per terminal: tunnel type terminals: 10 mm² rigid; 10 mm² flexible; 10 mm² flexible with ferrule.
• Ambient temperature: -20 to 50 °C in operation.

Where the A9S60220 is used in Oman and the GCC

In Oman and the GCC, modular switch-disconnectors of this kind appear in building services boards, small industrial panels, utility rooms of water and desalination plants, camp accommodation, and equipment skids in the oil and gas sector. They give electricians a local isolation point without opening the whole panel.

Panel temperature is the practical concern in the region: compare the operating range of -20 to 50 °C with the temperature inside the enclosure on a summer afternoon, and add shading or ventilation if the margin is small. The A9S60220 should be treated as a switching and isolating device and combined with suitable protection.
