Schneider Acti9 iC60 RCBO in Malaysia: true 2-pole RCBOs, but no 10mA model

Electricians who are careful about water-heater circuits often ask for two things in an RCBO. They want a true 2-pole device, and they want one rated to IEC 61009-2-1, the standard for voltage-independent RCBOs, which keep working if the neutral is lost. Most of Schneider’s Acti9 iC60 RCBOs on its Malaysian list are both of those things. As of 6 October 2026, though, none of them is 10mA, the sensitivity the Energy Commission requires on water-heater circuits.

What Schneider Malaysia lists

Schneider Malaysia’s product list for the Acti9 iC60 RCBO range has nine references:

2P models: Schneider’s Malaysian pages describe both poles as protected, rated 10kA under EN/IEC 61009-2-1 and 15kA under EN/IEC 60947-2 at 220–240V. They’re 36mm wide (four 9mm modules), twice the width of the 18mm Easy9 RCBO. These pages also describe two features:

• a “Visitrip” indicator that “reduces intervention time by showing the faulty circuit”;
• a “Visisafe” green strip confirming the contacts are physically open before downstream work.

A9D17332: Schneider’s page describes three protected poles at 220–240V. It’s not a 4-pole device, so it doesn’t meet the 4-pole requirement for three-phase water-heater circuits described below. Check its intended use with the supplier.

Type A-SI: Schneider doesn’t define “A-SI” on these Malaysian pages. It’s generally described as a Type A variant with extra immunity to nuisance tripping, so confirm with Schneider if that matters for your circuit. Type A detects ordinary AC leakage and pulsating DC leakage from electronics. At 300mA, the Type AC models are far too insensitive to protect people from shock, so they don’t replace a 30mA or 10mA device.

For a water heater?

Not on their own. GP/ST/No.6/2016, the Energy Commission’s water-heater guideline, requires two things:

• leakage protection of 10mA or less;
• a 2-pole RCD on a single-phase heater circuit, and a 4-pole one on three-phase.

The 2P iC60 RCBOs meet the 2-pole requirement and the voltage-independence preference. At 30mA or 300mA, though, they don’t meet the 10mA requirement.

For a Schneider device at 10mA from its Malaysian lists, the options are:

• The Easy9 RCBO, EZ9D16625 or EZ9D16632 (25 or 32A, Type A). It’s 1P+N, so confirm with the supplier how it switches the neutral against the 2-pole requirement. Its datasheet also cites the voltage-dependent RCBO standard.
• A 2-pole 25A 10mA Easy9 RCCB (EZ9R14225, or the Type A EZ9R26225) with a suitable MCB. At 25A it suits heaters up to about 4.46kW.
• A 2-pole 25A 10mA Acti9 iID RCCB (A9R10225 Type AC, A9R20225 Type A, A9R30225 Type A-SI) with a suitable MCB, on the same 25A terms.
• The Acti9 iDPN Vigi 10mA RCBO (A9D02610, A9D02616, A9D08616), which is rated to the voltage-independent standard but only at 10 and 16A, so it suits heaters under about 2.86kW.
• The Vigi iC60 block A9V10225 (2P 25A 10mA, Type AC) fitted to a 2-pole iC60 MCB: Schneider describes it as voltage independent, so with a 2P iC60 it gives the 2-pole, voltage-independent 10mA combination these iC60 RCBOs can’t, at a much higher price.

Our water heater guide explains the choice.

The 30mA models do fit as protection on individual socket or appliance circuits. A per-circuit RCBO there means a fault trips only that circuit, instead of a shared RCCB taking out half the house.

Other Acti9 RCBOs you may see advertised

Malaysian sellers also list Acti9 RCBOs that aren’t on this Schneider Malaysia list:

• Plus Power: an iC60H RCBO 1P+Ns 240V (A9D11820, A9D12820; the description shown is a 20A C-curve, 1-protected-pole, 100mA Type A variant). Also an iC60H2 RCBO 2P 110V (A9D19220, A9D19225, plus A9D11220; 30mA Type A). Both descriptions cite IEC 61009-2-2, the voltage-dependent standard, and the 110V label suggests the iC60H2 isn’t meant for 230V circuits.
• Search listings: RS Components Malaysia shows a 4-pole 16A 30mA iC60 RCBO, element14 Malaysia shows A9D17316, and eezee shows A9D11216, described as “Vd”.
• Shopee: a store lists an “A9D10820” as 10mA 20A, but Schneider Malaysia has no product page for that code.

Treat these as seller listings and confirm the exact code’s specification before buying.

Where to find them

The Malaysian sellers we found for references on Schneider Malaysia’s list are industrial distributors:

• RS Components Malaysia lists A9D27220 (stock no. 341-549).
• KVC lists A9D37210, with prices only for signed-in accounts.
• element14 Malaysia lists the 3-pole A9D17332.

Ask for the exact reference. “iC60 RCBO” covers several sub-ranges with different poles, sensitivities and standards.
