Built for commercial applications, this 25-amp miniature circuit breaker delivers reliable thermal-magnetic overcurrent protection. The two-pole unit operates at 120/240VAC. The bolt-on design ensures a secure connection within Siemens P1 through P5 panelboards. It includes load side lugs that accept 10-8 AWG copper or 10-6 AWG aluminum wire. With a 22kAIC interrupting rating, this BLH type breaker handles higher fault currents. It is fully HACR rated for safe use with HVAC equipment.
Which panelboards accept the Siemens B225H circuit breaker?
This bolt-on breaker is designed specifically for installation in Siemens P1, P2, P3, P4, and P5 commercial panelboards.
What does the H in the B225H catalog number signify?
The H indicates that this is a Type BLH breaker. It provides a high interrupting rating of 22kAIC at 120/240VAC, which is required for systems with higher available fault currents compared to standard 10kAIC BL series breakers.
Is the B225H circuit breaker HACR rated?
Yes, it carries a full HACR rating, meaning it is tested and approved for safely protecting heating, air conditioning, and refrigeration equipment circuits.
Can I use the Siemens B225H to replace a legacy ITE B225H?
Yes. Siemens acquired ITE, and the current Siemens B225H serves as the direct, manufacturer-approved replacement for older ITE B225H models.
How does the B225H mount to the panelboard?
It utilizes a bolt-on connection that fastens directly to the panelboard bus. This provides a highly secure, vibration-resistant mechanical and electrical connection required in commercial distribution equipment.
What type of trip mechanism does the B225H use?
It features a fixed thermal-magnetic trip unit. The thermal component provides long-time delay protection against overloads, while the magnetic component offers instantaneous protection against short circuits.
