Product FAQs

6 answers
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.
