Product Description

Thermal magnetic circuit breakers, like the BQ2B100 are found in many light industrial and light commercial panels across the United States. In addition to Siemens, ITE and Gould both manufactured this bolt-in style breaker for industrial applications and they are mechanically and electrically interchangeable. The electromagnet characteristics of this breaker allow it to trip instantaneously under large surges in current (e.g., short circuits). A bimetallic strip within the breaker will respond to less extreme but longer-term over-current conditions. So designed, Wadsworth / Connecticut circuit breakers protect conductors against overloads and conductors and connected apparatus, such as motors and motor starters, against short circuits.

Typical applications for the BQ2B100 include small pumps, some bathroom heaters and small electric motors, as well as lights, electrical outlets. Prior to installation, get familiar with local code to insure proper installation of the BQ2B100 and to ensure compliance with all local rules.

Siemens Molded Case Circuit Breakers, like the BQ2B100, are designed to provide circuit protection for low voltage distribution protection for low voltage distribution systems. They are described by NEMA as, "a device for closing and interrupting a circuit between separable contacts under both normal and abnormal conditions," and furthermore as, ". . . a breaker assembled as an integral unit in a supporting and enclosing housing of insulating material." The NEC describes them as, "A device designed to open and close a circuit by non-automatic means, and to open the circuit automatically on a predetermined overload of current, without injury to itself when properly applied within its rating."
