描述
浪涌保护设备（SPD）可针对持续若干微秒的瞬态过压为设备提供保护。通过限制设备在这些事件发生时的过电压，成本高昂的损坏和停工可以得到减少。采用4+0配置的浪涌保护器件可用于120 V至480 V标称电压的子配电板应用。

Surge Protection Devices

SPD2 4+0 SERIES

Class II/Type 2/Type 1 CA Pluggable Multi-Pole

Description

Surge protection devices (SPDs) provide equipment protection

from transient overvoltage events lasting micro-seconds. By

limiting the overvoltage to the equipment during these events,

costly damage and downtime can be mitigated.

Visual Life

Indicator

The surge protection devices for the 4+0 conﬁguration are

available for 120 V to 480 V nominal voltage sub-distribution

board applications.

Pluggable RC

Connector

Features & Beneﬁts

FEATURES

BENEFITS

Internal Conﬁguration

Ensures low-residual voltage during high-energy

surge events and higher nominal discharge current

to prevent disruption, downtime, and degradation or

damage to equipment

Capability to clamp and

withstand high-energy

transients

UL Recognized and

VDE-IEC compliant in

single part number

One component can be utilized globally, reducing

inventory needs and simplifying allocation of parts

Interlocking tab

mechanism

Secures module to withstand vibration

No additional

overcurrent protection

devices required in

UL applications

Reduces the number of components and costs

required for protection

Compact footprint

Increases panel design ﬂexibility
