Heinemann offers both thermal circuit breakers for low-current applications and hydraulic-magnetic circuit breakers for high-performance high-current applications.
 KD Series - Thermal Circuit Protectors
Heinemann thermal circuit protectors are available in both AC and DC ratings in accordance with UL and CSA standards. Heinemann offers a range of ratings from 0.25A through 15A at 250VAC and/or 32VDC. The protectors are installed in a hole similar to a glass fuse holder and can be mounted from front or rear.
Hydraulic Magnetic Circuit Breakers
Heinemann hydraulic-magnetic circuit breakers are available in both AC and DC ratings in accordance with UL, CSA and VDE standards. Heinemann offers a number of equipment, branch and main circuit breaker products that meet American, European and Asian agency listings, ensuring products designed with Heinemann may be designed, built and sold worldwide.The hydraulic-magnetic circuit breakers may be configured with a variety of non-delayed or time-delayed trip characteristics. Heinemann hydraulic-magnetic circuit breakers carry 100% rated current even at elevated temperatures and will trip instantaneously upon short-circuit. The breaker overload-trips according to a time-delay versus overload current trip curve. High in-rush configurations are also available for protecting loads like distribution transformers and power supplies.The Heinemann hydraulic-magnetic circuit breaker is the original hydraulic magnetic circuit and equipment protector that offers three major advantages over thermal device
Advantages
-
Ability to carry 100% of rated current without nuisance tripping at elevated temperatures
Withstand current inrush without overload tripping
-
Unique construction provides precise trip characteristics across a broad temperature range
Heinemann breakers are available in circuit configurations such as the commonly-used Series Trip; Dual Rating for tripping at two discrete current ratings; Relay Trip for remote trip actuation isolated from the line voltage and Shunt Tap for remote tripping using the line voltage. An integrated auxiliary switch is available for remote alarm applications. Also available are a variety of screw, stud, clip and plug-in terminal options. Several handle color, marking and location options are also available.
Applications
Heinemann breakers are often used in telecom, data center, medical, locomotive, marine, lighting and HVAC applications in several different configurations, from .02A up to 1200A, from one to six poles and up to 100kA interruption current. |
