FOR IMMEDIATE RELEASE
Two New Telecom Power Distribution Systems
Provide Unprecedented Power For Their Size
CHICAGO – March 18, 2002 – Today E-T-A Circuit Breakers announced the X8340-S08 and
S07, two compact, high-current, power distribution solutions.
X8340-S08 Power Distribution Solution
Based on E-T-A’s circuit breaker technology, the rack-mounted X8340-S08 accommodates up
to eight circuit breakers and protects expensive and critical equipment from short circuits and
current overloads. No competing solution can match the X8340-S08 for its distribution of up to
800A of DC power in a small 2U, 19-inch chassis.
The X8340-S08 is ideally suited for use in telecom switching stations and cellular sites, but it
also may be used to distribute power to almost any type of rack-based electronics, such as a
process control system.
The X8340-S08 has four 200A DC power inputs, each distributing power to two 100A (50A
parallel-pole) E-T-A 8340 Series circuit breakers. The system may be configured for a nonredundant supply of 800A, or it may be configured for 400A with power redundancy; if power to
the first pair of inputs fails, the system accommodates equipment that will automatically switch
power to the second pair of power inputs.
Its small frame size and high level of protection are the result of E-T-A’s 50 years of
experience in power distribution combined with its circuit breaker technologies. E-T-A’s 8340
circuit breaker is highly compact for its current rating. Its magnetic trip mechanism has a fast
trip profile, providing maximum protection of electronic equipment. Unique among magnetic
circuit breakers with this rating, the 8340 has a reset mechanism with a push-pull actuator.
The actuator's locking mechanism makes the device tolerant of vibration up to 10 g – an
important consideration for use in remote cellular stations located in earthquake zones and
other high risk environments. In addition, the push-pull design resists accidental actuation,
unlike competing circuit breakers having toggle-switch actuators.
In telecom applications, power shutdown can disrupt customer communications and be very
costly for the service provider. To avoid this, the circuit breakers in X8340-S08 system are hot
swappable.
E-T-A has partnered with connector supplier Amphenol to make the connections on X8340S08 unit the safest and most secure in this product category. Input and output connectors
utilize Amphenol’s unique Hi-Lok™ technology: an 8 mm locking pin requiring only 15 pounds
of connection force but requiring 50 pounds of force to disconnect. In addition, the Hi-Lok
female connector completely shields the connection, providing a touch-safe design.
Competing solutions require a Lexan cover or an enclosure, which complicates access to the
connections and increases cost.
Optional LED indicating lights display the status of power input, breaker trip indication, low
voltage, and output current loop sensing. Optional auxiliary contacts in the circuit breakers can
be used to communicate an alarm signal. The system's interruption capacity is 3500A at 80V
DC. Operating voltage is -80 to +80V DC.
X8340-S07 Power Distribution Solution
The X8340-S07 power distribution solution provides up to 175A via seven E-T-A 25A 8340
Series circuit breakers. Like the X8340-S08 system, all circuit breakers are hot swappable in
the X8340-S07. The plug-in circuit breakers feature blade-style quick-connect terminals for
easy installation and removal.
Interrupting capacity is 2000A at 80V DC. Operating voltage is -80 to +80V DC.
The vertically oriented X8340-S07 system (58.2 mm W x 282 mm H x 322 D) is designed to be
rack mounted.
Pricing and Availability
Despite feature advantages, E-T-A's new power distribution solutions are competitively priced.
Prices for the 8340-S08 start at $1500 in production volume, and for the 8340-S07 at $1000 in
production volume.
Standard units are available eight weeks ARO. In most cases, the system will be customized
for the needs of specific applications. For more information, visit the E-T-A web site,
www.etacbe.com, and submit application information. Custom nameplates and molding are
also available.
