General Information NOTE: For more information on other standard and optional trip unit features, see Siemens Electronic Trip Units for SB Encased Systems Breakers Information and Instruction Guide Bulletin IPIM-2203B and the Sentron Systems Breaker Energy Communicating Trip Unit Information and Instruction Guide Bulletin IPIM-2208A. This patented construction provides a higher interrupting capacity within a smaller housing than can be achieved by more conventional construction.
PAGE 4
General Information Compact Size For space-limited installations, the 1200A and 2000A frames offer a common width of 15 1/2 inches, a common depth of only 12 1/8 inches, a common mounting footprint, and common bus center lines. This compact, shallow depth (even with drawout breakers) permits stacking of six 800A or 1200A breakers or four 2000A breakers in a standard switchboard. This packaging is made possible by the insulated-encased construction and thermal performance of the SB breaker.
PAGE 5
Description Stationary and Moveable Drawout Elements Simplified Minimum Depth Drawout Mechanism The two elements of a drawout constructed SB Encased Systems Breaker are the stationary drawout element and the moveable drawout element. The stationary drawout element mounts from the front or bottom into a standard switchboard. Bottom mounting flanges are provided for optional mounting arrangements. The moveable drawout element mounts onto the stationary drawout element’s two extension rails.

Type“TL”Trip Unit Accessories Plug-in Display Module The Plug-in Display Module can be added to the type “TL” electronic trip unit only to provide digital current readout of each phase in amperes. The module also provides load monitor set points at 60, 70, 80, 90 and 100% of the continuous ampere setting. Also provided are two ampere demand functions. May be used in conjunction with the Alarm Relay on page 16 or the Bell Alarm and Alarm Relay Combination Module on page 15 for remote alarming.

Internal and External Accessories Table N: Electrical Operators Electric Operators function to automatically charge the SB breaker’s stored energy mechanism. Each operator includes a Remote Closing Solenoid for closing the breaker from a remote location and an electronic controller which provides anti-pump protection and remote charging capability and indication.
PAGE 16
Internal and External Accessories Shunt Trips Allows the breaker to be opened from a remote location. Included is an auxiliary switch for remote indication of breaker “open” or “closed” status. UL listed for field installation.
PAGE 17
Internal and External Accessories Alarm Relays The Alarm Relay provides 1 NO and NC (Form C) contact. When used with the “TL” Trip Unit Display Module or Ground Fault Monitor, the relay changes state when the current set-point is exceeded. When used with the SB-EC Trip Unit, the relay changes state whenever an alarm is active. If the current falls below the set point or the alarm is no longer active, the contact returns to its normal state.

External Accessories and ACCESS™ Communications Type “TL” Trip Unit Auxiliary Power Module A device used to bring power into the SB breaker type “TL” electronic trip unit only so that the trip unit can be tested via the integral testing functions when the breaker is withdrawn from the Stationery Drawout Element. It is required to trip the breaker’s shunt trip when no primary power is applied to the breaker or when “bench testing” the electronic trip unit.
