EV Chargers — Power Your Electric Vehicle with Confidence

Electric vehicles are transforming the way the UK travels — and having a reliable, fast home or commercial EV charger is essential. Terelec Technologies now offers a range of smart EV charging solutions designed for homeowners, businesses, and commercial property operators.

Why Choose a Terelec EV Charger?

• Fast Charging: Our EV chargers support up to 7.4kW single-phase and 22kW three-phase charging speeds, cutting charge times dramatically compared to a standard 3-pin socket.
• Smart Connectivity: Wi-Fi and app-enabled models allow you to schedule charging during off-peak hours, monitor energy usage, and manage multiple charge points remotely.
• Universal Compatibility: Our chargers are compatible with all major EV brands including Tesla, Nissan Leaf, BMW i-series, Volkswagen ID range, Hyundai Ioniq, and more.
• OZEV/OLEV Grant Ready: Our residential EV chargers are eligible for the UK Government’s Electric Vehicle Homecharge Scheme (EVHS) grant — saving homeowners up to £350 on installation.
• Weather-Resistant Build: Rated to IP65 and above, all Terelec EV chargers are designed for outdoor UK conditions — rain, frost, and everything in between.
• Professional Installation: All units must be installed by a qualified electrician to BS 7671 standards. Our team can recommend certified installers across the UK.

Our EV Charger Range Includes:

• 7.4kW Smart Home EV Charger — Ideal for residential driveways and garages. App-controlled, compact design, with Type 2 socket for universal compatibility.
• 22kW Three-Phase Commercial EV Charger — Perfect for office car parks, retail sites, and hospitality venues. Supports simultaneous dual-vehicle charging.
• Tethered EV Charger Units — Pre-fitted cable for convenient plug-and-charge without needing a separate Type 2 cable.
• Untethered (Socket) EV Charger Units — Flexible socket-based units compatible with a wide range of EVs and PHEVs.

RCBs / RCDs — Residual Current Breakers That Save Lives

A Residual Current Breaker (RCB), also known as a Residual Current Device (RCD), is one of the most important safety devices in any electrical installation. It monitors current flow and trips the circuit within milliseconds if a fault is detected — protecting people from electric shock and preventing electrical fires.

Terelec supplies a comprehensive range of RCBs and RCDs for all installation types, from domestic consumer units to commercial distribution boards.

Types of RCBs Available at Terelec:

• RCCB (Residual Current Circuit Breaker): Provides residual current protection without overcurrent protection. Ideal when used alongside MCBs in a split-load consumer unit.
• RCBO (Residual Current Breaker with Overcurrent): Combines RCD and MCB functionality in a single device — providing both fault current and overcurrent protection in one unit. Space-saving and highly efficient.
• RCD Socket Outlets: Built-in RCD protection at the socket level — ideal for kitchens, bathrooms, outdoor sockets, and anywhere additional protection is required.
• Portable RCDs: Plug-in RCD adapters for use with extension leads and power tools on site.

Key Specifications:

• Trip Sensitivity: Available in 10mA (high sensitivity), 30mA (standard), and 100mA (selective) ratings.
• Operating Voltage: 230V AC single phase, 400V three phase options available.
• Compliance: All RCBs meet BS EN 61008 / BS EN 61009 standards and are 18th Edition Wiring Regulations (BS 7671) compliant.

MCBs — Miniature Circuit Breakers for Reliable Overcurrent Protection

Miniature Circuit Breakers (MCBs) are the cornerstone of any modern electrical distribution system. They protect wiring and equipment from overloads and short-circuit faults — automatically disconnecting the circuit when current exceeds safe limits, and resetting easily once the fault is resolved.

Unlike traditional fuses, MCBs can be reset instantly without the need to replace components — making them faster, safer, and more economical for both residential and commercial installations.

Our MCB Range:

• Type B MCBs: Designed for resistive and some inductive loads. Ideal for lighting circuits, socket outlets, and general household wiring. Trips at 3–5 times rated current.
• Type C MCBs: Suitable for higher inductive loads including motors, air conditioning units, and commercial equipment. Trips at 5–10 times rated current.
• Type D MCBs: For heavy industrial loads with very high inrush currents such as transformers, welding equipment, and large motors. Trips at 10–20 times rated current.
• AFDD (Arc Fault Detection Device) MCBs: Advanced next-generation MCBs that detect dangerous arc faults — significantly reducing the risk of electrical fires. Required in certain installations under the 18th Amendment to BS 7671.

Available Ratings:

• Current ratings: 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A
• Single pole, double pole, and three-pole configurations
• Compatible with all major consumer unit brands including Hager, Schneider Electric, ABB, Legrand, and Wylex
• Fully compliant with BS EN 60898-1 and BS 7671 18th Edition
