Description
Designed for advanced control, the Siemens QJH23B22500S01 is a 3-pole, 225A MCCB featuring a factory-installed 120VAC shunt trip. This allows users to remotely open the circuit for safety. The thermal-magnetic unit mounts into Siemens P1, P2, and P3 panelboards and motor control centers. It can be replaced by the QRH23B225 when utilizing an S01QR2 shunt trip accessory. Delivering a 22kAIC rating at 240VAC, this QJ-frame breaker includes load lugs and is HACR rated for HVAC equipment.Specifications

Product FAQs
6 answersWhich Siemens panelboards accept the QJH23B22500S01 circuit breaker?
This unit mounts directly into Siemens P1, P2, and P3 panelboards, as well as compatible switchboards and motor control centers. As a bolt-on breaker, it secures directly to the bus to provide a rigid, high-reliability connection for commercial distribution.
What does the 00S01 suffix indicate on this QJH23B225 breaker?
The 00S01 suffix means this breaker features a factory-installed 120V AC shunt trip. This accessory allows the breaker to be tripped remotely for automated control or emergency shutdown.
What is the modern replacement for this legacy QJ frame breaker?
For modern panelboard upgrades, this legacy QJ frame is typically replaced by the QR frame equivalent, such as the QRH23B225. To replicate the shunt trip function, you will need the S01QR2 accessory, and a QR strap kit is required to adapt the new frame to the panelboard bus.
What wire gauge range is supported by the load lugs on this breaker?
The factory-installed load side lugs accept conductors ranging from 6 AWG to 300 kcmil. Always verify the specific torque requirements printed on the breaker label to ensure a secure and code-compliant connection.
Is the QJH23B22500S01 breaker HACR rated for HVAC applications?
Yes, this molded case circuit breaker is HACR rated, making it fully compliant for protecting heating, air conditioning, and refrigeration equipment.
How does the 120V AC shunt trip operate during a fault or emergency?
When a 120V AC control voltage is applied to the shunt trip terminals, it energizes an internal coil that mechanically trips the breaker. This allows fire alarm panels, emergency stop buttons, or control systems to safely disconnect power to the circuit from a remote location.
