HAVELLS 3+1 FP AC SPD

Description

The term Havells 3+1 FP AC SPD refers to a specific type of Surge Protection Device (SPD) made by Havells. Here’s the breakdown:

1. Havells: The brand, known for electrical products and solutions.
2. 3+1: This refers to the number of poles in the surge protection device:
   • 3: Typically refers to three poles (often for three-phase circuits). This means the SPD is designed to protect all three phases of a three-phase electrical system.
   • 1: Refers to one neutral pole. In addition to protecting the three phases (live wires), the device also protects the neutral line.

   This combination makes the device suitable for three-phase power systems, where protection is needed across all three live wires and the neutral line.

3. FP: Stands for Four-Pole, meaning the device has four poles (three for phases and one for neutral). The “four-pole” configuration is commonly used in industrial or large commercial installations where three-phase power is supplied.
4. AC: Indicates that the device is designed for Alternating Current (AC) electrical systems.
5. SPD: Stands for Surge Protection Device. This device is used to protect electrical circuits and equipment from voltage spikes or surges, which can be caused by lightning, switching operations, or other disruptions in the electrical supply.

Summary:

A Havells 3+1 FP AC SPD is a four-pole surge protection device designed for three-phase AC electrical systems, offering protection for all three live (phase) wires and the neutral wire. It helps safeguard electrical equipment from high voltage surges, ensuring the longevity and safety of appliances, machinery, and other sensitive devices.

This kind of SPD is typically used in industrial, commercial, or large residential setups where three-phase power is used.
