Description

Designed for commercial facilities, the Siemens B210000S01 provides robust 100A overcurrent protection alongside remote tripping functionality. The factory-installed 120VAC shunt trip allows facility managers to disconnect power from a secondary control location. This BL series component installs into Siemens P1, P2, P3, P4, and P5 panelboards using a secure bolt-on connection. It accepts up to 1/0 AWG wire. The 2-pole MCCB features a 10kAIC interrupting capacity at 120/240VAC.

Product FAQs

6 answers
Which panelboards are compatible with the Siemens B210000S01?

This bolt-on circuit breaker is designed specifically for installation in Siemens P1, P2, P3, P4, and P5 commercial panelboards. Because it uses a bolt-on connection, it cannot be installed in standard plug-on residential load centers.

What does the 00S01 suffix indicate on this circuit breaker?

The 00S01 suffix designates a factory-installed 120VAC shunt trip. This allows the breaker to be tripped remotely by applying a 120V control signal to the shunt trip coil, which is commonly used for emergency shutdowns or automated control systems.

Does the shunt trip require a separate control power source?

Yes, the factory-installed 120VAC shunt trip requires an external 120V control circuit to operate the remote tripping function. When voltage is applied to the coil, it mechanically forces the breaker contacts open to disconnect the load.

What wire sizes and materials are accepted by the B210000S01 terminals?

The terminal lugs are designed for 4 AWG to 1/0 AWG copper conductors or 2 AWG to 1/0 AWG aluminum conductors. Always apply an approved oxide inhibitor when terminating aluminum wire and torque to the manufacturer specifications printed on the breaker.

Can this breaker replace older ITE models?

Yes, because Siemens acquired ITE, the B210000S01 serves as a direct replacement for older ITE B210000S01 or ITE BL frame breakers equipped with a 120VAC shunt trip.

How does the thermal-magnetic trip mechanism operate in this breaker?

The fixed thermal-magnetic trip unit provides dual protection. The thermal element offers a delayed response to sustained overcurrent conditions, preventing nuisance tripping from temporary motor inrush currents. The magnetic element provides an instantaneous trip to rapidly clear severe short circuits.
