Class B Non-Pluggable SPD

Class B Surge Protectors are an essential component of any AC power electrical installation, as they provide protection against direct lightning surges and over-voltage for low-voltage systems. According to NBC 2016, it is mandatory to install Class B Surge Protectors in the Main Distribution Panel of the structure, building, or application to mitigate direct lightning surges at 10/350-microsecond waveform.

Technical Specifications
Surge Handling Capacity : 50 kA (L-N); 100 kA (N-PE)
Response Time : ≤ 100 ns
Voltage Protection Level : ≤1.5 kV

Class B Pluggable SPD

Class B Pluggable SPDs are designed to withstand direct lightning strikes and other high-energy transients, and typically use a combination of surge suppression components, such as metal oxide varistors (MOVs), gas discharge tubes, and silicon avalanche diodes (SADs), to divert the excess voltage and current away from the protected equipment and into a ground wire or other path to the earth.

Technical Specification
Surge Handling Capacity : 50 kA (L-N); 100 kA (N-PE)
Response Time : ≤ 100 ns
Voltage Protection Level : ≤1.5 kV

Class C Pluggable SPD

Class C Pluggable Single Phase and Three Phase SPDs are typically installed at the point of use or distribution boards within a building or facility to protect against transients that are generated within the electrical system itself. They are often used in conjunction with Class B SPDs, which are designed to protect against direct lightning strikes and other high-energy transients at the service entrance of the building.

Technical Specification
Nominal Discharge Surge Current, In (8/20) μs : 20kA
Max. Discharge Current, Imax : 40kA
Response Time : ≤25ns
Voltage Protection Level : ≤1.5 kV

Class B+C Pluggable SPD

Class B+C Single Phase and Three Phase Pluggable Surge protection device designed to protect low voltage distribution system against transient overvoltage by a direct and indirect lightning strike and switching operations.  Class B+C SPDs offer comprehensive surge protection against a wide range of transient events, making them an important component of any surge protection strategy by providing reliable surge protection.

Technical Specification
Surge Handling Capacity : 20 kA (L-N); 40 kA (N-PE)
Response Time : ≤25 ns (L-N), ≤100 ns (N-PE)
Voltage Protection Level : ≤1.5 kV

Class B+C Non Pluggable

The Class B+C Surge Protective Device (SPD) is a surge protection system that provides protection against both direct and indirect lightning strikes. It combines technologies from both Class B and Class C surge protection systems, which makes it well-suited for applications that demand a high level of protection against electrical surges.

Technical Specification
Surge Handling Capacity : 50 kA (L-N); 100 kA (N-PE)
Response Time : ≤ 100 ns
Voltage Protection Level : ≤1.5 kV

Class B+C Progressive SPD

A progressive SPD (Surge Protective Device) is a type of surge protector that uses multiple stages of protection to protect electrical and electronic equipment from transient overvoltage. The device typically consists of two or more stages of protection, each designed to handle a specific type of surge. 
Technical Specification
Surge Handling Capacity : 60 kA (L-N), 100 kA (N-PE)
Response Time : ≤ 25 ns
Voltage Protection Level : ≤1.5 kV
