More Than One Relay. 6 Reasons to Upgrade Your Go-To.
Stay ahead of compliance, avoid costly downtime, and maximise operational efficiency.
At NewElec, we often find that clients rely on one or two “go-to” relays they know and trust. But the truth is, NewElec offers a broad, high-performance range of protection relays, each engineered for specific environments, applications, and industries.
To help you get more out of your protection strategy, we’ve highlighted our top six bestsellers, including their key functions, ideal use cases, and why they continue to deliver value across South Africa’s most demanding industries.
LA Series Relay
Function: Thermal overload and locked rotor protection.
Industry Use: Mining, water treatment plants, HVAC systems, and pump stations.
Why You Should Choose It: Rugged and reliable, the LA Series is designed for tough loads and unpredictable grid conditions. It’s a favourite in sectors that require durable protection against overheating and motor burnout, delivering peace of mind and long service life.
GA Series Relay
Function: Earth leakage protection with adjustable sensitivity.
Industry Use: MCC panels, utilities, public sector infrastructure.
Why You Should Choose It: GA Relays are essential for environments where personnel safety and electrical integrity are non-negotiable. Combined with CBCTs, they offer fast, accurate detection of earth leakage faults, ensuring compliance and minimising downtime risk.
NewCode Relay
Function: Smart relay with dual Ethernet, digital logging, and SCADA integration.
Industry Use: Smart factories, infrastructure projects, high-performance plants.
Why You Should Choose It: NewCode enables real-time diagnostics, remote configuration, and full industrial protocol support (Modbus TCP, Profibus, Profinet, and Ethernet/IP). It’s the relay of choice for OEMs and plants adopting Industry 4.0 strategies.
KB Series Relay
Function: Compact digital motor protection with overload, unbalance, and phase loss protection.
Industry Use: OEM panels, MCC boards, utilities, and general industry.
Why You Should Choose It: If you’re tight on panel space but high on expectations, the KB Series delivers reliable protection without sacrificing performance. It’s ideal for panel builders and engineers looking to maximise space and safety simultaneously.
KD Series Relay
Function: Thermal, earth fault, and phase protection in hazardous zones.
Industry Use: Petrochemical plants, chemical storage, mining operations.
Why You Should Choose It: With high surge resistance, vibration durability, and flameproof compatibility, KD relays are purpose-built for high-risk environments. When failure isn’t an option, KD provides resilient protection for both people and equipment.
KG Series Relay
Function: Feeder protection relay with wireless Bluetooth configuration, thermal overload protection, and motor monitoring.
Industry Use: Low-voltage feeder systems in substations, control panels, and energy distribution — ideal for utilities, municipalities, and industrial automation.
Why You Should Choose It: Offers safe, wireless configuration and diagnostics, perfect for engineers needing quick setup and reliable protection in high-voltage or hard-to-access environments, without the complexity of SCADA integration.
