Engineered for control panel applications, the Siemens BQ2B025QLD provides dependable thermal-magnetic circuit protection. This two-pole, 25-amp molded case circuit breaker operates at 120/240VAC to defend against overloads and short circuits. It utilizes a convenient DIN rail mounting style, allowing for quick integration into compatible enclosures. The inclusion of Insta-Wire technology significantly reduces installation time. This common-trip breaker features a 10kAIC interrupting rating.
How is the Siemens BQ2B025QLD installed in a panel?
Unlike standard plug-on or bolt-on breakers used in load centers, the BQ2B025QLD snaps directly onto a standard DIN rail. It is designed specifically for control panels and DIN rail enclosures, and it includes factory-installed lugs on both the line and load sides.
What does the QLD suffix indicate on the BQ2B025QLD catalog number?
The QLD suffix designates that this BQ series breaker is built on the BQXD frame for DIN rail mounting. It also confirms that the breaker is supplied with both line and load side lugs for cable-in, cable-out wiring.
What are the acceptable wire gauges for the BQ2B025QLD lugs?
The terminal lugs accommodate 14 to 6 AWG copper wire or 12 to 6 AWG aluminum wire. Ensure proper torque specifications are followed during installation in your control panel.
What type of protection does the BQ2B025QLD provide?
It features a fixed thermal-magnetic trip unit with long-time and instantaneous (LI) functions. The thermal component protects against sustained overloads, while the magnetic component trips immediately during short circuits.
Can I install the BQ2B025QLD in a standard Siemens residential load center?
No. The BQ2B025QLD is a DIN rail mounted breaker intended for industrial control panels and specialized DIN rail enclosures. It will not fit in standard plug-on residential load centers.
