HEB3B100B | Siemens Molded Case Circuit Breaker

The HEB3B100B is a Siemens molded case circuit breaker belonging to the HEB Series, designed for robust electrical protection in industrial and commercial applications. It features a 3-pole configuration, suitable for three-phase systems, with a rated current capacity of 100 amps and a voltage rating of 600 volts. The breaker is engineered to handle high fault currents, boasting an impressive interrupting capacity of 65,000 amps at 480 volts, ensuring reliable operation in environments prone to electrical faults. 

As a thermal magnetic circuit breaker, the HEB3B100B incorporates both Long-Time (overload) and Instantaneous (short-circuit) trip functions. This dual-trip mechanism enhances its ability to promptly respond to varying levels of electrical anomalies, protecting downstream equipment and circuits from damage. 

Operating within a temperature range of up to 40 degrees Celsius, the breaker is optimized for performance in standard industrial conditions. Its bolt-on connection type facilitates secure installation onto electrical panel boards, providing stability and ease of maintenance.
