Remote Signaling Contact
• Option to remotely monitor the status of the surge protector.
• Simplified cabling thanks to a single terminal for monitoring all poles.
SURGE PROTECTION DEVICES
Today’s residential, commercial and industrial set-ups are heavily reliant on the continuous and efficient running of electrical and electronic systems. Over-voltage surges are a major cause of failure of these equipment. Such transient over-voltage surges are often generated due to direct/indirect effects of lightning strikes, switching of utility grid or capacitor banks, electrical accidents, turning on/off of nearby heavy load machines, AC chillers, motors, pumps, circuit-breaker tripping etc. Surges can cause destruction of electronic circuitry components, logic failures and breakdowns. Loss of operation, loss of service, loss of data, and loss of production can be huge and by far higher than the cost of damaged equipment. Long term exposure to lower level transient over-voltages can also lead to premature ageing of equipment. Havells offers a comprehensive range of Surge Protection Devices designed to protect your installation by limiting transient over-voltages and diverting surge currents to ground.

End of Life Indicator
Green shows the satisfactory operation and Red indicates that Cartridge must be replaced.
Pluggable Cartridges
• Faulty cartridges can be replaced without changing the entire SPD.
• Cartridges can be replaced with mains voltage ON.
• All cartridges are marked with characteristics for ease of maintenance.
Dedicated Protection of the Neutral
The 1 P+N and 3 P+N SPDs with dedicated protection of the neutral pole discharge the common and differential mode overvoltages that may occur in installations with TT and TNS systems, when there is a voltage surge.
