GCV-60-385-3+1 AC Power Surge Protective Device, 60kA Imax, 3+1 Configuration

Description

The GCV-60-385-3+1 is a Class II (C-level) surge protective device for AC power systems, intended for the second stage of protection at load equipment. It is a 3+1 configuration device rated for a 385V maximum continuous operating voltage and a 60kA maximum discharge current (8/20μs).

Product Overview

The GCV-60 series surge protective device is used for second-stage (Class C) lightning and surge protection of load equipment in power systems. The GCV-60-385-3+1 variant uses a 3+1 pole configuration. The device is designed to be installed in LPZ1 zones or directly inside distribution cabinets (switch boxes).

Applications

The GCV-60-385-3+1 is used for second-stage (Class C) lightning and surge protection of load equipment in AC power systems. It can be installed in LPZ1 zones or directly in distribution cabinets (switch boxes).

Installation and Use

• The device can be installed in LPZ1 zones or directly in distribution cabinets (switch boxes).
• It can be fixed on a 35mm electrical DIN rail.
• The device is connected in parallel to the power line. “L/+” connects to the phase line or positive line; “N/-” connects to the neutral line or negative line. The copper conductor cross-section at both ends of the device is 10-35mm².
• An overcurrent protection device such as an air switch or fuse must be installed ahead of the SPD in the circuit.
• The grounding connection should use the shortest possible wire. The device uses terminal grounding; the grounding wire must be connected to the lightning protection ground.
• The protected line should maintain sufficient safety distance from the incoming line and ground line to avoid secondary induction.
• Under conditions not exceeding the specified requirements, the device does not require long-term maintenance, only routine system maintenance. If the green indicator window turns red during use, the device is damaged and must be repaired or replaced.
