Surge Protective Devices for Electrical Installations

A surge protective device limits transient overvoltages and diverts surge current away from connected equipment. SPDs are used as part of a coordinated electrical protection strategy and may be required depending on the installation type, risk assessment and applicable BS 7671 requirements.

Type 1, Type 2 and Combined Type 1+2 SPDs

Type 1 SPDs are designed for locations where partial lightning current may need to be discharged, typically at the origin of installations where this level of protection is required. Type 2 SPDs are widely used to protect against switching surges and transient overvoltages associated with indirect lightning effects. Combined Type 1+2 devices provide both functions in one unit where appropriate.

Single-Phase, Three-Phase and Solar PV Surge Protection

The range includes surge protection for single-phase and three-phase AC installations, together with dedicated DC SPDs for solar PV systems. Choose a device that matches the system voltage, number of poles, earthing arrangement and application. Dedicated category ranges make it easier to compare suitable options for consumer units, distribution boards and PV installations.

Choosing the Correct Surge Protective Device

  • Check whether Type 1, Type 2 or combined Type 1+2 protection is required.
  • Match the SPD to the supply voltage, AC or DC system and number of poles.
  • Confirm compatibility with the installation’s earthing arrangement.
  • Check discharge ratings, backup protection and coordination requirements.
  • Follow the manufacturer’s installation instructions and applicable BS 7671 requirements.
