Selection Guides for Low Voltage Buyers
Practical guides on choosing between MCB, RCBO and AFDD devices, picking a smart breaker connection, protecting DC circuits and specifying enclosures.
MCB RCBO and AFDD What Each Device Actually Protects
Three DIN devices that look alike protect against three different faults. Getting the selection wrong leaves a real risk uncovered.
WiFi Zigbee or 4G Choosing a Smart Breaker Connection
The protection is the same. The difference between the three smart ranges is how the device reaches the person who wants to switch it.
Why a DC Circuit Needs a DC Rated Breaker
An AC breaker fitted to a solar string is one of the most common sourcing mistakes on the DC side and the reason the DZ47Z-63 series exists.
How to Read a Breaker Trip Curve
A Type C device is the default across most of this range. Knowing what the curve means stops nuisance tripping and undersized protection.
Specifying a Distribution Box for the Installation Site
Metal or plastic, indoor or outdoor, surface or flush. The enclosure decision is usually made last and causes the most site problems.
