About The BNSD

Electrical safety in homes and buildings is often taken for granted—until something goes wrong. One of the most dangerous and overlooked electrical faults is a broken or missing neutral connection, which can happen due to cable theft, incorrect wiring, or connections that loosen over time. 

When this occurs, the risk of electric shock, electrocution, fire, and serious damage to appliances increases dramatically.

The BNSD Type 3.0 (Broken Neutral Safety Device) is a simple yet powerful solution designed to keep people and property safe. In the absence of a neutral, the BNSD automatically causes the earth leakage device to trip, cutting power before harm can occur. This fast response helps prevent dangerous situations and protects valuable household and commercial equipment.

Designed to be easy to install and affordable, the BNSD fits into both single-phase and three-phase distribution boards, making it suitable for homes, offices, and a wide range of electrical installations. It’s a small addition that delivers big peace of mind—because every installation deserves an extra layer of protection.

The BNSD Type 3.0 helps you:

• Protect lives from electric shock and electrocution
• Reduce the risk of electrical fires
• Safeguard appliances and sensitive equipment
• Add essential protection against neutral failure

Every home and installation should have one. 

Get your BNSD Type 3.0 today and protect what matters most.
