Schneider Electric A9S60332 Acti9 iSW 3P 32 A Switch

A9S60332: Acti9 iSW 3P, 32 A switch-disconnector

The A9S60332 is a Schneider Electric Acti9 iSW modular switch, listed by the manufacturer as: switch Acti9 iSW – 3 poles – 32 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 A9S60332 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, 3P gives the number of poles and the 32 A figure is the rated operational current at 415 V. The category is AC-22A. The three-pole 32 A switch is the typical isolator for a small three-phase load: a pump, a compressor, a fan or a small machine fed by 415 V without a neutral. It is also used as the isolation point of an incoming sub-board of modest size.

Technical specifications of the A9S60332

Size, terminals and wiring of the A9S60332

The A9S60332 measures 77 mm high, 36 mm wide and 70 mm deep, which is 4 modules of 9 mm on the DIN rail and weighs 117 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.

How to read the ratings of the A9S60332

Utilisation category AC-22A means the switch is built for resistive and mixed inductive loads including moderate overloads, so the 32 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 A9S60332 is a means of switching and isolating, not of protecting. It has no neutral pole, so it is not for loads that need the neutral switched. At 36 mm wide it takes four 9 mm modules, which is more than the two-pole version even though only three poles are active.

Acti9 iSW references compared with the A9S60332

It shares the rating of A9S60232 but has three poles and a 36 mm width, and the datasheet lists a weight of 117 g against about 65 g for the two-pole device.

Selection checklist for the A9S60332

Before ordering the A9S60332, confirm the following.

• Load current at the supply voltage: 32 A at 415 V.
• Number of poles: 3P, 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: 4 modules of 9 mm, 36 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 A9S60332 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 A9S60332 should be treated as a switching and isolating device and combined with suitable protection.

Installation and maintenance of the A9S60332

Snap the A9S60332 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.
