Product Attributes

Introduction

The BSPD Series of surge protective devices are tested by Underwriters Laboratory and Listed to UL 1449, 4th Edition to help ensure equipment is protected with highly reliable surge protection technology. Delta and Wye system units are available in three configurations to increase application flexibility. The BSPD Series is for installation external to an electrical enclosure or panelboard. Application of BSPD Series units throughout a facility will help ensure that equipment is protected.

Features

• BSPD uses Bussmann series SurgePOD thermally protected Metal Oxide Varistor (MOV) technology to safely shunt overvoltages to ground while its thermal disconnect capability eliminates the need for additional fusing
• 200kA SCCR meets the highest NEC requirements
• Models available to meet the overvoltage protection needs of Wye and Delta electrical systems from 208 to 600 volts, 3 - phase
• BSPD has the highest nominal discharge current (In) of 20kA per UL 1449 4th Edition. This rating indicates the SPD’s ability to handle a number of large - magnitude surges over a short period of time and remain operational.
• 120kA to 400kA surge current capacity (Imax) ratings meet the needs of larger switchgear and power distribution panel applications
• Optional Form C contact relay, EMI/RFI filtering and surge counter available to meet additional system requirements.
• 200kA Short - Circuit Current Rating (SCCR)
• NEMA 1 or NEMA 4X enclosures
• RoHS compliant

Applications

• service entrances
• distribution switchboards
• panelboards
• point - of - use
