B29000S01 - 90Amp Circuit Breaker

B29000S01 - 90Amp Circuit Breaker

The Siemens B29000S01 circuit breaker combines standard overcurrent protection with built-in remote trip capability for applications that require added control and safety. Designed for 120/240VAC systems, this 90 amp, 2-pole breaker helps protect your electrical circuits from overloads and short circuits while supporting reliable operation in commercial, industrial, and residential distribution equipment.

This model includes a factory-installed 120V shunt trip, allowing the breaker to be remotely opened through an external signal. That makes it a common choice for emergency shutoff systems, fire alarm integration, HVAC equipment, and automated control setups where remote disconnect capability is needed. 

The bolt-on Type BL design provides a secure installation in compatible Siemens panelboards and load centers. Its compact size also helps you during panel upgrades and replacement work where available space may be limited. With a 10 kA interrupting rating and UL 489 listing, the B29000S01 is built for everyday electrical distribution applications that require dependable circuit protection and remote trip functionality.
