Product Overview
The Lorain® BD 800 provides disconnection and overcurrent protection for +24 VDC
or -48VDC battery strings. Disconnects are available in single and dual positions. Overcurrent protection is provided by a user-specified fuse or breaker rated from 300 to 800
amps per position. A shunt, included with the over-current protection device, measures
charge and discharge current and can be monitored by a Lorain
Emerson Monitoring Equipment, or any monitoring system using a 25mV shunt input.
The disconnect can be wall-mounted or 23" rack mounted as required. Breakers equipped
with voltage trip coils can be used to satisfy code requirements for EPO circuits.
The built-in shunt measures charge and discharge current for the batteries. Battery damage is prevented and battery life is increased with the use of a built-in PS shunt card and
an optional VPS or LVS MCA set up to limit battery recharge current. Voltage trip breakers
permit remote operation. An EPO switch may be used to comply with local and national
fire codes (NEC).

VPS or LVS MCA,
Safety and security features include a cover that can be locked in place during maintenance operations to prevent access to the battery breakers or fuses. A door alarm switch
provides a set of contacts that will change state whenever the door is opened. Any access
or operation of the door can be monitored using this feature. The door latch can also be
tool-secured for restricted access.
