Enhanced protection status indicators

Unlike many SPDs that only have single-color indicators, all

BSPD units include green and red Light Emitting Diodes (LEDs)

that indicate the true protection status for each phase.

If power is removed from any one phase, the unit’s LEDs

continue to indicate the protection status on that phase —

regardless if power is applied to the phase. This feature ensures

proper indication.

Although many SPDs on the market have N-G surge protection,

they do not always have a means of monitoring and indicating

the protection status of that mode. All BSPD units for Wye

systems also contain green and red LED surge protection status

indicators for the Neutral-to-Ground (N-G) connection. Like the

phase protection status LEDs, the N-G protection status LEDs

show the true protection status in the N-G mode.

By specifying the BSPD, users are supplied with accurate

information concerning the surge protection status of their

electrical systems.

Configurations

The BSPD provides users with three configurations. These are:

•

Basic (UL Type 1 - can be installed in UL Type 2 locations)

•

Standard (UL Type 2)

•

Standard with surge counter (UL Type 2)

The proper configuration can be selected based on application

requirements or specification.
