TEMPEARL B-33E Circuit Breaker

Description:

The TEMPEARL B-33E 20A Circuit Breaker is used in industrial and commercial electrical distribution systems to provide overcurrent and short-circuit protection for branch circuits and equipment operating at up to 220 VAC. Commonly installed in control panels, motor control centers, distribution boards, and industrial machinery where reliable circuit protection is essential for safe operation. Maintenance electricians and automation technicians use this circuit breaker for repair, retrofit, expansion, or replacement of worn or obsolete molded case circuit breakers.

Applications:

The TEMPEARL B-33E 20A Circuit Breaker is commonly used in manufacturing facilities, machine tools, HVAC equipment, conveyor systems, pumps, and general-purpose industrial power distribution. Its thermal-magnetic trip mechanism protects electrical circuits from overloads and short circuits while providing dependable operation in demanding industrial environments. As a legacy molded case circuit breaker, the B-33E series has been widely used in electrical control panels and has been superseded by the B-33EC series for many applications.
