Are Eco Harmony's modular components compatible with its distribution boards?

Yes. Eco Harmony's RCBOs, MCBs and RCDs are rated to work with its TPN distribution board range, which accepts standard 10kA-rated devices.

Does Eco Harmony sell RCBOs, MCBs, RCDs and SPDs in trade quantities?

Yes, customers can get in touch for trade pricing on bulk orders for panel building or stocking up on a job.

Which brands of RCBOs does Eco Harmony stock?

Eco Harmony's RCBO range spans WCED, CHINT, Garo and Bituo Technik.

Modular Components

RCBOs, MCBs, RCDs & SPDs

Din-rail protective devices for populating distribution boards and control panels — stocked across multiple brands, in the combinations and quantities panel builders and commercial electricians actually need.

Whether you're populating one of our TPN distribution boards, building your own panel, or just topping up stock for a job, we hold a wide range of modular protective devices — RCBOs, MCBs, RCDs and Type 2 surge protection devices — to BS 7671. Everything below is designed to work together, and to pair with our 3-phase distribution boards.

RCBOs

Combined overcurrent and earth-leakage protection in a single module, stocked across WCED, CHINT, Garo and Bituo Technik.

Configuration	Rating	Sensitivity	Curve
1P+N	16A / 32A	30mA, Type A	C-curve
2-pole	32A / 40A	30mA, Type A	C-curve
3P+N	16A / 32A	30mA, Type A	C-curve
4-pole	32A / 40A	30mA, Type A	C-curve

MCBs

Standard C-curve miniature circuit breakers for overcurrent protection, sized to pair with our TPN boards and 10kA-rated distribution equipment.

View the MCB range →

RCDs

Residual current devices for earth-leakage protection across a circuit or a whole board, where you need RCD protection separate from overload protection.

Surge Protection Devices (SPDs)

Type 2 surge protection is fitted as standard on our TPN distribution boards, and standalone SPDs are available where you're retrofitting protection into an existing board or building a bespoke panel.

Frequently Asked Questions

What's the difference between an RCBO and an RCD?

An RCD (residual current device) only protects against earth-leakage faults. An RCBO combines that with overcurrent protection in a single module, so it does the job of an RCD and an MCB together on one circuit.

Are these components compatible with your distribution boards?

Yes — our RCBOs, MCBs and RCDs are rated to work with our TPN distribution board range, which accepts standard 10kA-rated devices.

Do you sell in trade quantities?

Yes, get in touch for trade pricing on bulk orders of RCBOs, MCBs, RCDs or SPDs for panel building or stocking up on a job.

Which brands do you stock?

Our RCBO range spans WCED, CHINT, Garo and Bituo Technik, giving you a choice of brand and price point for the same protection.

What if I need a component you don't list?

We can offer custom builds and have access to an enormous range of components beyond what's listed on the site — it's not possible to list them all, so get in touch with your spec and we'll see what we can source.

Stocking up for a job or a panel build?
