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 Series, users are supplied with accurate

information concerning the surge protection status of their electrical

systems.

Configurations

The BSPD Series 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.
