The Siemens SHND69100A is a 3 Pole solid state molded case circuit breaker with a current rating of 1000 Amps and a voltage rating of 600VAC. It has an interrupting rating of 65kAIC at 480V. The SHND69100A has a bolt-on connection type and includes long time and instantaneous trip functions.
Which panelboards and switchboards are compatible with the SHND69100A circuit breaker?
This unit-mount ND-frame breaker is designed for use in Siemens P5 Panelboards, S5 Power Panels, and Sentron Switchboards.
What are the standard lug requirements for this 1000A breaker?
To accommodate the rated four 250-500 kcmil copper or aluminum conductors per phase, this breaker typically utilizes a 4-barrel mechanical lug kit, such as the Siemens 3TA4N8500.
What does the LI trip function indicate on this electronic trip unit?
The LI designation means the solid-state trip unit provides adjustable Long-Time (overload) and Instantaneous (short-circuit) protection. It does not include Short-Time or Ground Fault functions.
Is the SHND69100A a plug-in or bolt-on breaker?
This is a bolt-on, unit-mount circuit breaker. It is not designed for plug-in panelboard configurations.
Can the SHND69100A physically replace older thermal-magnetic ND-frame breakers?
Yes. Because it belongs to the standard ND frame group, it shares the same 16-inch by 9-inch by 6-inch footprint as older thermal-magnetic variants, allowing for direct physical retrofitting.
